RESUMO
OBJECTIVE: Total transfemoral (TF) access has been increasingly used during fenestrated-branched endovascular aortic repair (FB-EVAR). However, it is unclear whether the potential decrease in the risk of cerebrovascular events is offset by increased procedural difficulties and other complications. The aim of this study was to compare outcomes of FB-EVAR using a TF vs upper extremity (UE) approach for target artery incorporation. METHODS: We analyzed the clinical data of consecutive patients enrolled in a prospective, nonrandomized clinical trial in two centers to investigate the use of FB-EVAR for treatment of complex abdominal aortic aneurysms (CAAA) and thoracoabdominal aortic aneurysms (TAAA) between 2013 and 2022. Patients were classified into TF or UE access group with a subset analysis of patients treated using designs with directional branches. End points were technical success, procedural metrics, 30-day cerebrovascular events defined as stroke or transient ischemic attack, and any major adverse events (MAEs). RESULTS: There were 541 patients (70% males; mean age, 74 ± 8 years) treated by FB-EVAR with 2107 renal-mesenteric TAs incorporated. TF was used in175 patients (32%) and UE in 366 patients (68%) including 146 (83%) TF and 314 (86%) UE access patients who had four or more TAs incorporated. The use of a TF approach increased from 8% between 2013 and 2017 to 31% between 2018 and 2020 and 96% between 2021 and 2022. Compared with UE access patients, TF access patients were more likely to have CAAAs (37% vs 24%; P = .002) as opposed to TAAAs. Technical success rate was 96% in both groups (P = .96). The use of the TF approach was associated with reduced fluoroscopy time and procedural time (each P < .05). The 30-day mortality rate was 0.6% for TF and 1.4% for UE (P = .67). There was no early cerebrovascular event in the TF group, but the incidence was 2.7% for UE patients (P = .035). The incidence of MAEs was also lower in the TF group (9% vs 18%; P = .006). Among 237 patients treated using devices with directional branches, there were no significant differences in outcomes except for a reduced procedural time for TF compared with UE access patients (P < .001). CONCLUSIONS: TF access was associated with a decreased incidence of early cerebrovascular events and MAEs compared with UE access for target artery incorporation. Procedural time was decreased in TF access patients irrespective of the type of stent graft design.

OBJECTIVES: To investigate the impact of 1-year changes in aneurysm sac diameter on patient survival after fenestrated-branched endovascular aortic repair (FB-EVAR) of complex abdominal aortic aneurysms or thoracoabdominal aortic aneurysms. METHODS: We reviewed the clinical data of patients enrolled in a prospective nonrandomized study investigating FB-EVAR (2013-2022). Patients with sequential follow up computed tomography scans at baseline and 6 to 18 months after FB-EVAR were included in the analysis. Aneurysm sac diameter change was defined as the difference in maximum aortic diameter from baseline measurements obtained in centerline of flow. Patients were classified as those with sac shrinkage (≥5 mm) or failure to regress (<5 mm or expansion) according to sac diameter change. The primary end point was all-cause mortality. Secondary end points were aortic-related mortality (ARM), aortic aneurysm rupture (AAR), and aorta-related secondary intervention. RESULTS: There were 549 patients treated by FB-EVAR. Of these, 463 patients (71% male, mean age, 74 ± 8 years) with sequential computed tomography imaging were investigated. Aneurysm extent was thoracoabdominal aortic aneurysms in 328 patients (71%) and abdominal aortic aneurysms in 135 (29%). Sac shrinkage occurred in 270 patients (58%) and failure to regress in 193 patients (42%), including 19 patients (4%) with sac expansion at 1 year. Patients from both groups had similar cardiovascular risk factors, except for younger age among patients with sac shrinkage (73 ± 8 years vs 75 ± 8 years; P < .001). The median follow-up was 38 months (interquartile range, 18-51 months). The 5-year survival estimate was 69% ± 4.1% for the sac shrinkage group and 46% ± 6.2% for the failure to regress group. Survival estimates adjusted for confounders (age, chronic pulmonary obstructive disease, chronic kidney disease, congestive heart failure, and aneurysm extent) revealed a higher hazard of late mortality in patients with failure to regress (adjusted hazard ratio, 1.72; 95% confidence interval, 1.18-2.52; P = .005). The 5-year cumulative incidences of ARM (1.1% vs 3.1%; P = .30), AAR (0.6% vs 2.6%; P = .20), and aorta-related secondary intervention (17.0% ± 2.8% vs 19.0% ± 3.8%) were both comparable between the groups. CONCLUSIONS: Aneurysm sac shrinkage at 1 year is common after FB-EVAR and is associated with improved patient survival, whereas sac enlargement affects only a minority of patients. The low incidences of ARM and AAR indicate that failure to regress may serve as a surrogate marker for nonaortic-related death.
RESUMO
OBJECTIVE: To assess the impact of secondary intervention (SI) on health-related quality of life (HR-QOL) after fenestrated-branched endovascular aortic repair (FB-EVAR) for complex abdominal aortic aneurysms and thoracoabdominal aortic aneurysms. BACKGROUND: The effect of SI after FB-EVAR on physical and mental HR-QOL has not been described. METHODS: A cohort of 430 consecutive patients enrolled in a prospective, nonrandomized study to evaluate FB-EVAR (2013-2020) was assessed with 1325 short-form 36 HR-QOL questionnaires preoperatively and during follow-up visits. SIs were classified as major or minor procedures. Endpoints included patient survival, freedom from aortic-related mortality (ARM), freedom from SIs, and changes in HR-QOL physical component score (PCS) and mental component score. RESULTS: There were 302 male with mean age 74±8 years treated by FB-EVAR for 133 complex abdominal aortic aneurysms and 297 thoracoabdominal aortic aneurysms. After a mean follow up of 26±20 months, 97 patients (23%) required 137 SIs. At 5 years, freedom from any SI was 64%±4%, including freedom from minor SIs of 77%±4% and major SIs of 87%±3%. There was no difference in patient survival and freedom from ARM at same interval. On adjusted analysis, minor SIs correlated with improved survival. SIs had a negative correlation with PCS ( r =-0.8). There were no significant changes in mental component score with SIs. Predictors for SIs were fluoroscopy time, graft design, and aneurysm sac change. CONCLUSION: SIs were needed in nearly 1 out of 4 patients treated by FB-EVAR with no effect on patient survival or ARM. SI resulted in decline in PCS.

OBJECTIVE: To define the risks associated with the replacement of dual antiplatelets for alternate medication regimens. BACKGROUND: Patients undergoing transcarotid artery revascularization (TCAR) for atherosclerotic disease in the Vascular Quality Initiative database from September 2016 to June 2022 were included. In all, 29,802 TCAR procedures were captured between 2016 and 2022, consisting of 24,651 (82.7%) maintained on dual antiplatelet therapy (DAPT) and 5151 (17.3%) on alternative regimens. METHODS: Patients maintained on DAPT were compared with those on alternative regimens consisting of any combination of single antiplatelet monotherapy and/or anticoagulation. RESULTS: On univariable analysis, patients on alternative medications were more likely to experience in-hospital death, ipsilateral stroke, any stroke, and transient ischemic attacks compared with patients in the DAPT group. The mortality rate was higher at 1 year in the alternative cohort (4.7% vs 7.0%, P <0.01). The use of alternate medication regimens was associated with increased odds of stroke and the composite outcome of in-hospital stroke/death compared with DAPT. There was also a significant association between alternative medication use and increased odds of in-hospital transient ischemic attack, immediate stent occlusion, and return to the operating room. At 1 year, there was no significant difference in the incidence of stroke between the 2 groups. However, the use of alternate regimens was associated with higher 1-year of mortality after multivariable adjustment. CONCLUSIONS: Patients not maintained on DAPT after TCAR experienced an increased risk of stroke and death in the perioperative and follow-up periods. Increased surgeon vigilance is required to ensure compliance with dual antiplatelets as recommended.

OBJECTIVE: To describe the technical pitfalls and outcomes of iliofemoral conduits during fenestrated-branched endovascular repair (FB-EVAR) of complex abdominal aortic aneurysms (CAAAs) and thoracoabdominal aortic aneurysms (TAAAs). METHODS: We retrospectively reviewed the clinical data of 466 consecutive patients enrolled in a previous prospective nonrandomized study to investigate FB-EVAR for CAAAs/TAAAs (2013-2021). Iliofemoral conduits were performed through open surgical technique (temporary or permanent) in patients with patent internal iliac arteries or endovascular technique among those with occluded internal iliac arteries. End points were assessed in patients who had any iliac conduit or no conduits, and in patients who had conduits performed prior or during the index FB-EVAR, including procedural metrics, technical success, and major adverse events (MAE). RESULTS: There were 138 CAAAs, 141 extent IV, and 187 extent I-III TAAAs treated by FB-EVAR with an average of 3.89 ± 0.52 vessels incorporated per patient. Any iliac conduit was required in 35 patients (7.5%), including 24 patients (10.4%) treated between 2013 and 2017 and 11 (4.7%) who had procedures between 2018 and 2021 (P = .019). Nineteen patients had permanent conduits using iliofemoral bypass, 11 had temporary iliac conduits, and 5 had endoconduits. Iliofemoral conduits were necessary in 12% of patients with extent I to III TAAA, in 6% with extent IV TAAA, and in 3% with CAAA (P = .009). The use of iliofemoral conduit was more frequent among women (74% vs 27%; P < .001) and in patients with chronic obstructive pulmonary disease (49% vs 28%; P = .013), peripheral artery disease (31% vs 15%; P = .009), and American Society of Anesthesiologists classification of III or higher (74% vs 51%; P = .009). There were no inadvertent iliac artery disruptions in the entire study. The 30-day mortality and MAE were 1% and 19%, respectively, for all patients. An iliofemoral conduit using retroperitoneal exposure during the index FB-EVAR was associated with longer operative time (322 ± 97 minutes vs 323 ± 110 minutes vs 215 ± 90 minutes; P < .001), higher estimated blood loss (425 ± 620 mL vs 580 ± 1050 mL vs 250 ± 400 mL; P < .001), and rate of red blood transfusion (92% vs 78% vs 32%; P < .001) and lower technical success (83% vs 87% vs 98%; P < .001), but no difference in intraoperative access complications and MAEs, compared with iliofemoral conduits without retroperitoneal exposure during the index FB-EVAR and control patients who had FB-EVAR without iliofemoral conduits, respectively. There were no differences in mortality or in other specific MAE among the three groups. CONCLUSIONS: FB-EVAR with selective use of iliofemoral conduits was safe with low mortality and no occurrence of inadvertent iliac artery disruption or conversion. A staged approach is associated with shorter operating time, less blood loss, and lower transfusion requirements in the index procedure.

OBJECTIVE: The aim of this study was to compare outcomes of fenestrated-branched endovascular aortic repair (FB-EVAR) of complex abdominal (CAAAs) and thoracoabdominal aortic aneurysms (TAAAs) in patients with or without prior history of abdominal open surgical (OSR) or endovascular aortic repair (EVAR). METHODS: The clinical data of consecutive patients enrolled in a prospective, non-randomized study to evaluate FB-EVAR for treatment of CAAAs and TAAAs was reviewed. Clinical outcomes were analyzed in patients with no previous aortic repair (Controls), prior EVAR (Group 1), and prior abdominal OSR (Group 2), including 30-day mortality and major adverse events (MAEs), patient survival and freedom from aortic-related mortality (ARM), secondary interventions, any type II endoleak, sac enlargement (≥5 mm), and new-onset permanent dialysis. RESULTS: There were 506 patients (69% male; mean age, 72 ± 9 years) treated by FB-EVAR, including 380 controls, 54 patients in Group 1 (EVAR), and 72 patients in Group 2 (abdominal OSR). FB-EVAR was performed on average 7 ± 4 and 12 ± 6 years after the index EVAR and abdominal OSR, respectively (P < .001). All three groups had similar clinical characteristics, except for less coronary artery disease in controls and more TAAAs and branch stent graft designs in Group 2 (P < .05). Aneurysm extent was CAAA in 144 patients (28%) and TAAA in 362 patients (72%). Overall technical success, mortality, and MAE rate were 96%, 1%, and 14%, respectively, with no difference between groups. Mean follow up was 30 ± 21 months. Patient survival was significantly lower in Group 2 (P = .03), but there was no difference in freedom from ARM and secondary interventions at 5 years between groups. Group 1 patients had lower freedom from any type II endoleak (P = .02) and sac enlargement (P < .001), whereas Group 2 patients had lower freedom from new-onset permanent dialysis (P = .03). CONCLUSIONS: FB-EVAR was performed with high technical success, low mortality, and similar risk of MAEs, regardless of prior history of abdominal aortic repair. Patient survival was significantly lower in patients who had previous abdominal OSR, but freedom from ARM and secondary interventions were similar among groups. Patients with prior EVAR had lower freedom from type II endoleak and sac enlargement. Patients with prior OSR had lower freedom from new-onset dialysis.

OBJECTIVE: Dual antiplatelet therapy (DAPT) continues to be the preferred medication regimen after the placement of a carotid stent using the transcarotid revascularization (TCAR) technique despite a dearth of quality data. Therefore, this investigation was performed to define the risks associated with antiplatelet choice. METHODS: We queried all patients who underwent TCAR captured by the Vascular Quality Initiative from September 2016 to June 2022, to determine the association between antiplatelet choice and outcomes. Patients maintained on DAPT were compared with those receiving alternative regimens consisting of single antiplatelet, anticoagulation, or a combination of the two. A 1:1 propensity-score match was performed with respect to baseline comorbidities, functional status, anatomic/physiologic risk, medications, and intraoperative characteristics. In-hospital and 1-year outcomes were compared between the groups. RESULTS: During the study period, 29,802 procedures were included in our study population, with 24,651 (82.7%) receiving DAPT and 5151 (17.3%) receiving an alternative antiplatelet regimen. A propensity-score match with respect to 29 variables generated 4876 unique pairs. Compared with patients on DAPT, in-hospital ipsilateral stroke was significantly higher in patients receiving alternative antiplatelet regimens (1.7% vs 1.1%, odds ratio [95% confidence interval]: 1.54 [1.10-2.16], P = .01), whereas no statistically significant difference was noted with respect to mortality (0.6% vs 0.5%, 1.35 [0.72-2.54], P = .35). A composite of stroke/death was also more likely in patients receiving an alternative regimen (2.4% vs 1.7%, 1.47 [1.12-1.93], P = .01). Immediate stent thrombosis (2.75 [1.16-6.51]) and a nonsignificant trend toward increased return to the operating room were more common in the alternative patients. Conversely, the incidence of perioperative myocardial infarction was lower in the alternative regimen group (0.4% vs 0.7%, 0.53 [0.31-0.90], P = .02). At 1 year after the procedure, we observed an increased risk of mortality (hazard ratio [95% confidence interval]: 1.34 [1.11-1.63], P < .01) but not stroke (0.52 [0.27-0.99], P = .06) in patients treated with an alternative medication regimen. CONCLUSIONS: This propensity-score-matched analysis demonstrates an increased risk of in-hospital stroke and 1-year mortality after TCAR in patients treated with an alternative medication regimen instead of DAPT. Further studies are needed to elucidate the drivers of DAPT failure in patients undergoing TCAR to improve outcomes for carotid stenting patients.

PURPOSE: The Provisional Extension to Induce Complete Attachment Technique (PETTICOAT) uses a bare-metal stent to scaffold the true lumen in patients with acute or subacute aortic dissections. While it is designed to facilitate remodeling, some patients with chronic post-dissection thoracoabdominal aortic aneurysms (TAAAs) require repair. This study describes the technical pitfalls of fenestrated-branched endovascular aortic repair (FB-EVAR) in patients who underwent prior PETTICOAT repair. TECHNIQUE: We report 3 patients with extent II TAAAs who had prior bare-metal dissection stents treated by FB-EVAR. Two patients required maneuvers to reroute the aortic guidewire, which was initially placed in-between stent struts. This was recognized before the deployment of the fenestrated-branched device. A third patient had difficult advancement of the celiac bridging stent due to a conflict of the tip of the stent delivery system into one of the stent struts, requiring to redo catheterization and pre-stenting with a balloon-expandable stent. There were no mortalities and target-related events after a follow-up of 12 to 27 months. CONCLUSION: FB-EVAR following the PETTICOAT is infrequent, but technical difficulties should be recognized to prevent complications from the inadvertent deployment of the fenestrated-branched stent-graft component in-between stent struts. CLINICAL IMPACT: The present study highlights a few maneuvers to prevent or overcome possible complications during endovascular repair of chronic post-dissection thoracoabdominal aortic aneurysm following PETTICOAT. The main problem to be recognized is the placement of the aortic wire beyond one of the struts of the existing bare-metal stent. Moreover, encroachment of catheters or the bridging stent delivery system into the stent struts may potentially cause difficulties.
RESUMO
BACKGROUND: Traumatic brain injury (TBI) and blunt thoracic aortic injury (BTAI) are the top two leading causes of death after blunt force trauma. Patients presenting with concomitant BTAI and TBI pose a specific challenge with respect to management strategy, because the optimal hemodynamic parameters are conflicting between the two pathologies. Early thoracic endovascular aortic repair (TEVAR) is often performed, even for minimal aortic injuries, to allow for the higher blood pressure parameters required for TBI management. However, the optimal timing of TEVAR for the treatment of BTAI in patients with concomitant TBI remains an active matter of controversy. METHODS: The Aortic Trauma Foundation international prospective multicenter registry was used to identify all patients who had undergone TEVAR for BTAI in the setting of TBI from 2015 to 2020. The primary outcomes included delayed ischemic or hemorrhagic stroke, in-hospital mortality, and aortic-related mortality. The outcomes were examined among patients who had undergone TEVAR at emergent (<6 vs ≥6 hours) or urgent (<24 vs ≥24 hours) intervals. RESULTS: A total of 100 patients (median age, 43 years; 79% men; median injury severity score, 41) with BTAI (Society for Vascular Surgery BTAI grade 1, 3%; grade 2, 10%; grade 3, 78%; grade 4, 9%) and concomitant TBI who had undergone TEVAR were identified. Emergent repair was performed for 51 patients (51%). Comparing emergent repair (<6 hours) to urgent repair (≥6 hours), no difference was found in delayed cerebral ischemic events (2.0% vs 4.1%; P = .614), in-hospital mortality (15.7% vs 22.4%; P = .389), or aortic-related mortality (2.0% vs 2.0%; P = .996) and no patient had experienced delayed hemorrhagic stroke. Likewise, repairs conducted in an urgent (<24 hours) setting showed no differences compared with those completed in an emergent (≥24 hours) setting regarding delayed ischemic stroke (2.6% vs 4.3%; P = .548), in-hospital mortality (18.2% vs 21.7%; P = .764), or aortic-related mortality (1.3% vs 4.3%; P = .654), and no patient had experienced delayed hemorrhagic stroke. CONCLUSIONS: In contrast to prior retrospective efforts, results from the Aortic Trauma Foundation international prospective multicenter registry have demonstrated that neither emergent nor urgent TEVAR for patients with concomitant BTAI and TBI was associated with delayed stroke, in-hospital mortality, or aortic-related mortality. In these patients, the timing of TEVAR did not have an effect on the outcomes. Therefore, the decision to intervene should be guided by individual patient factors rather than surgical timing.

OBJECTIVE: Blunt thoracic aortic injury (BTAI) is the second leading cause of death from blunt trauma. In the present study, we aimed to determine the outcomes of medical management (MM) for BTAI. We hypothesized from the results of several previously reported studies, that patients with a minimal aortic injury (BTAI grades 1 and 2) could safely be treated with definitive MM alone. METHODS: The Aortic Trauma Foundation international prospective multicenter registry was used to examine the demographics, injury characteristics, management, and outcomes of patients with BTAI. We analyzed a subset of patients for whom MM was initiated as definitive therapy. RESULTS: From November 2016 to April 2020, 432 patients (median age, 41 years; 76% male; median injury severity score, 34) with BTAI (Society for Vascular Surgery grade 1, 23.6%; grade 2, 14.4%; grade 3, 51.2%; grade 4, 10.9%) were evaluated. Of the 432 patients, 245 (57%) had received MM in the initial period and 114 (26.4%) had received MM as the planned definitive therapy (grade 1, 59.6%; grade 2, 23.7%; grade 3, 15.8%; grade 4, 0.9%). The most common mechanism of BTAI was a motor vehicle collision (60.4%). Hypotension was present on arrival in 74 patients (17.2%). Continuous titratable infusion of antihypertensive medication was used for 49.1%, followed by intermittent bolus administration (29.8%), with beta-blockers (74.6%) the most common agent used. Treatments were targeted to a goal systolic blood pressure for 83.3%, most often to a target goal systolic blood pressure <120 mm Hg (66.3%). The MM goals based on blood pressure control were attained in 64.0% (73 of 114). Twelve patients (10.5%; grade 1, 1; grade 2, 0; grade 3, 10; grade 4, 1) had required subsequent intervention after MM. Eleven patients (9.6%) had undergone thoracic endovascular aortic repair and one (0.9%) had required open repair for a grade 4 injury. The overall in-hospital mortality for patients selected for definitive MM was 7.9%. No aortic-related deaths had occurred in the patients receiving definitive MM. CONCLUSIONS: Approximately one in four patients with BTAI will receive MM as definitive therapy. The variation in the pharmacologic therapies used is considerable. MM for patients with minimal aortic injury (BTAI grades 1 and 2) is safe and effective, with a low overall intervention rate and no aortic-related deaths. These findings support the use of definitive MM for grade 2 BTAI.

BACKGROUND: In the present report, we have detailed the results derived from the adoption of transcarotid artery revascularization (TCAR) at a large health system based in the United States. METHODS: A retrospective review was performed of a prospectively maintained database capturing all carotid stents deployed using the ENROUTE neuroprotection device (Silk Road Medical, Sunnyvale, CA) and cerebral flow reversal. The demographics, intraoperative findings, and postoperative results were tabulated and reported. RESULTS: From September 2017 to December 2021, 429 TCAR procedures were attempted within the Memorial Hermann Health System. Preoperatively, all the patients were either asymptomatic with >70% stenosis (66.9%) or symptomatic with >50% stenosis (33.1%). The degree of stenosis was determined using computed tomography angiography and/or duplex ultrasound. We achieved a technical success rate of 99.1%, with the failures attributed to an inability to cross the lesion, an inability to track the stent, visualization of a flow-limiting dissection, and stent maldeployment for one patient each. During the 30-day perioperative period, nine strokes (2.3%) had occurred, three of which had occurred after discharge from the index operation and before the end of the 30-day period. No patient had experienced myocardial infarction. Five patients had died in the perioperative period. Three of the deaths were related to stroke, and two were attributed to cardiopulmonary events secondary to aspiration and likely pulmonary embolus. The mean follow-up after TCAR was 14.5 ± 12.0 months. During the follow-up period, two patients had required reintervention for in-stent stenosis. Ipsilateral to the implanted carotid stent, the overall (including perioperative) stroke incidence was 2.5%. Contralateral to the stent, the stroke incidence was 0.8%. The myocardial infarction rate was 0.8% during follow-up. Mortality in our study population was 5.1% during the follow-up period. CONCLUSIONS: After adoption of TCAR across the Memorial Hermann Health System, we found this procedure to be safe and efficacious with minimal perioperative risks comparable to the historically reported results associated with alternative carotid interventions.

OBJECTIVE: We compared the outcomes of fenestrated-branched (FB) endovascular abdominal aortic aneurysm repair (EVAR) using low-profile (LP) and standard-profile (SP) stent grafts for the treatment of complex abdominal aortic aneurysms (CAAAs) and thoracoabdominal aortic aneurysms (TAAAs). METHODS: We reviewed the clinical data of 466 consecutive patients (70% male; mean age, 74 ± 8 years) enrolled in a prospective nonrandomized study to investigate FB-EVAR for the treatment of CAAAs and TAAAs (2013-2021). The endpoints compared between the patients treated with LP (18F-20F) and SP (20F-22F) devices included procedural metrics, access-related complications, major adverse events (MAE), patient survival, freedom from secondary intervention, thromboembolic events, stent graft integrity issues, aneurysm sac enlargement, and the rate of sac shrinkage. RESULTS: Of the 466 aneurysms treated by FB-EVAR, 138 were CAAAs and 141 were extent IV and 187 extent I to III TAAAs, with a mean number of 3.9 ± 0.5 vessels stented per patient. LP devices had been used in 239 patients (51%) and SP devices in 227 patients (49%). LP devices had been used more frequently for chronic dissections (12% vs 7%; P = .041) and with preloaded systems (77% vs 65%; P = .005) and bilateral percutaneous femoral access (83% vs 74%; P = .020) and less frequently with upper extremity access (67% vs 88%; P < .001) and iliac conduits (2% vs 6%; P = .020). The patients treated using LP devices had experienced similar technical success (96% vs 97%; P = .527), with a shorter total operating time (225 ± 81 minutes vs 243 ± 78 minutes; P = .018), lower radiation exposure (median, 0.93 Gy; interquartile range [IQR], 0.94; vs median, 1.01 Gy; IQR, 0.91 Gy; P < .001), and less use of contrast (median, 135 mL; IQR, 68 mL; vs median, 144 mL; IQR, 80 mL; P = .008). No differences were found in the rates of iliofemoral access complications between the LP and SP device groups (1.3% vs 3.5%; P = .107). At 30 days, 5 patients had died (1%) and MAEs had occurred in 89 patients (19%), with no differences between the two groups. The mean follow-up was 28 months (95% confidence interval, 25-30 months). At 4 years, the patients treated with LP devices had had similar freedom from all-cause mortality (69% ± 6% vs 68% ± 4%; P = .199), freedom from aortic-related mortality (97% ± 1% vs 98% ± 1%; P = .488), freedom from any secondary intervention (65% ± 6% vs 70% ± 4%; P = .433), freedom from thromboembolic events (98% ± 1% vs 99% ± 1%; P = .364) and aneurysm sac enlargement (93% ± 3% vs 91% ± 3%; P = .293). However, the LP group had had less freedom from any integrity-related issues (92% ± 5% vs 100%; P < .001). The cumulative risk of sac shrinkage was greater for patients treated with LP devices (adjusted hazard ratio, 2.040; 95% confidence interval, 1.516-2.744; P < .001). CONCLUSIONS: FB-EVAR was performed with low rates of mortality and MAEs, irrespective of the device profile. However, the procedures performed with LP devices had had less need for iliac conduits and had had better procedural metrics. The use of LP devices resulted in higher rates of sac shrinkage. However, the results on stent graft integrity require future investigation.

BACKGROUND: Transcarotid revascularization (TCAR) is a carotid stenting technique in which an external shunt between the common carotid artery and femoral vein is created to induce cerebral flow reversal as protection against procedure-related plaque embolism. We completed this analysis to determine if prolonged cerebral flow reversal was associated with adverse perioperative outcomes. METHODS: A retrospective review of a combined carotid revascularization database separately maintained at 2 high-volume TCAR health systems was completed. Procedures with captured intraoperative reverse flow duration was included, stratified into two cohorts at a cut-off of 8 mi, and examined with univariate analysis. RESULTS: Within the predesignated study period, 800 patients received a carotid stent via the TCAR technique at Indiana University Health (n = 350) and Memorial Hermann Health Systems (n = 450). In 132 of these procedures, the duration of reverse flow time was not captured and, therefore, excluded from further analysis. Using our prespecified cutoff for extended reverse flow duration (ERFD), we generated 256 cases, leaving an additional 412 procedures completed with a short reverse flow duration. Baseline comorbidities were comparable with respect to individual diagnoses but the overall disease burden in ERFD patients was slightly higher by Charlson Comorbidity Index (5.3 ± 0.1 vs. 5.7 ± 0.1, P = 0.02). With respect to indications and high anatomic risk criteria, both groups were similar, with exception of the presence of a surgically inaccessible carotid bifurcation, which was more frequent in the ERFD procedures (5.3% vs. 10.2%, P = 0.02). Intraoperatively, more blood loss (40.9 ± 2.2 vs. 48.9 ± 2.9 mLs, P = 0.03), operative time (55.2 ± 0.8 vs. 76.3 ± 1.6 min, P < 0.01), radiation (126.3 ± 17.5 vs. 281.9 ± 28.5 mGys, P < 0.01), contrast volume (19.9 ± 0.4 vs. 26.9 ± 0.9 mLs, P < 0.01), and fluoroscopy time (3.3 ± 0.8 vs. 6.3 ± 0.3 min, P < 0.01) were noted in the patients with extended flow reversal. However, this did not increase the risk of stroke (2.7% vs. 2.0%, P = 0.61), myocardial infarction (0.5% vs. 0%, P = 0.53), or death (1.2% vs. 0.4%, P = 0.41) in the 30-day perioperative period. CONCLUSIONS: Extended cerebral flow reversal, defined here as greater than 8 min, was not associated with increased risk of stroke, myocardial infarction, or death in this institutionally derived series.

OBJECTIVE: To determine whether a vascular surgery trainee's participation in transcarotid revascularization (TCAR), a new technology, affects patient safety and outcomes. DESIGN: Retrospective, institutional review of our carotid database was performed. Patients who underwent TCAR were stratified based on whether a vascular trainee was present during the procedure. Relevant demographics, comorbidities, anatomical indication, perioperative courses, and adverse events in the postoperative period were captured for statistical analysis. SETTING: Data were obtained from affiliated Memorial Hermann Hospitals in Houston, Texas. PARTICIPANTS: All patients who underwent TCAR from September 2017 to January 2022 were included. RESULTS: Of 486 patients who underwent TCAR, 173 (35.6%) were performed in the presence of a trainee, and 313 (64.4%) were performed without a trainee. Subjects in the trainee cohort had more challenging anatomy, defined as a higher rate of carotid bifurcation above C2, restenotic disease, previous ipsilateral neck dissection, and neck radiation. The trainee cohort had higher rates of estimated blood loss (61.1 ± 66 vs. 35.5 ± 39 mL, p < 0.01), longer operative time (64.8 ± 30.3 vs. 57.9 ± 20.4 min, p < .01), longer cerebral blood flow reversal time (8.9 ± 6.1 vs. 7.9 ± 6.6 min, p = .01), and higher contrast administration (25.7 ± 12.0 vs. 21.1 ± 9.4 mL, p < .01). The ability to achieve technical success was similar between the two cohorts. There was no difference in the rates of cranial nerve palsy, ipsilateral stroke, hematoma, and stent thrombosis. Hospital length of stay, death (0% vs. 1.6%, p = .10), and stroke (1.1% vs. 2.8%, p = .22) were also similar between the two cohorts. CONCLUSION: Vascular surgery trainee's involvement during TCAR did not increase adverse outcomes, such as stroke and death, in the perioperative period. The results presented herein should encourage other teaching institutions to provide surgical trainees with supervised, hands-on experience during TCAR.
RESUMO
OBJECTIVE: The aim of this study was to investigate the midterm outcomes of fenestrated and branched endovascular aortic repair (FB-EVAR) of pararenal (PRA) and thoracoabdominal aortic aneurysms (TAAAs). SUMMARY BACKGROUND DATA: FB-EVAR has been associated with decreased morbidity compared to open repair, but there is limited midterm data. METHODS: A total of 430 patients (302 males, mean age 74â±â8âyears) treated by FB-EVAR were enrolled in a prospective, nonrandomized investigational device exemption study. Endpoints included 30-day mortality and major adverse events (MAEs), freedom from all cause and aortic-related mortality, target vessel patency, and freedom from secondary intervention and target vessel instability. RESULTS: There were 133 PRAs and 297 TAAAs with 1673 renal-mesenteric arteries incorporated by fenestrations or directional branches (3.9â±â0.5âvessels/patient). At 30 days or within the hospital stay if longer than 30 days, there were 4 (0.9%) deaths. MAEs included new-onset dialysis in 8 patients (2%), permanent paraplegia or stroke in 10 patients each (2%), and respiratory failure requiring tracheostomy in 2 patients (0.5%). After a mean follow-up of 26â±â20âmonths, there were 3 (0.7%) aortic-related deaths from SMA stent occlusion, gastrointestinal hemorrhage, or complications of open arch repair. At 5 years, freedom from all-cause and aortic-related mortality were 57%â±â5% and 98%â±â1%, respectively. Freedom from secondary intervention was 64%â±â4%, primary target vessel patency was 94%â±â1%, and freedom from target vessel instability was 89%â±â2% at same interval. One patient (0.2%) had nonfatal aneurysm treated using endovascular repair. CONCLUSION: FB-EVAR is safe and effective for treatment of PRA and TAAAs with low rate of aortic-related mortality and aneurysm rupture on midterm follow-up.

OBJECTIVE: The purpose of the present study was to assess the outcomes of fenestrated-branched endovascular aortic repair (FB-EVAR) using infrarenal aortic vs iliac sealing zones. METHODS: We reviewed the clinical data of 430 consecutive patients enrolled in a prospective nonrandomized study to evaluate FB-EVAR from 2013 to 2020. The outcomes were analyzed for patients with extent I to IV thoracoabdominal aortic aneurysms who had undergone FB-EVAR with distal implantation in the native infrarenal aorta. The minimum anatomic criteria for the use of infrarenal aortic seal was a >3-cm length of parallel aorta with a diameter of 18 to 32 mm without excessive thrombus or calcification. A control group matched for the extent of aortic disease with an iliac artery seal was used to compare the following endpoints: 30-day mortality, major adverse events, freedom from type Ib endoleak (TIbE), freedom from secondary interventions, and changes in the infrarenal aortic diameter. RESULTS: A total of 110 patients (55 men; mean age, 73 ± 8 years) were included in the present study, 55 with an infrarenal aortic distal seal and 55 with the iliac arteries as the sealing zone. Both groups had similar clinical characteristics and aneurysm extent and diameter, except for a greater number of men and higher serum creatinine in the iliac seal group. Technical success was obtained in 106 patients (96%) and was greater for the iliac sealing zone group (100% vs 93%; P = .04). The use of the infrarenal aortic sealing zone was associated with shorter endovascular (148 ± 56 minutes vs 191 ± 61 minutes; P < .001) and fluoroscopy (76 ± 28 minutes vs 96 ± 32 minutes; P < .001) times and lower radiation exposure (cumulative air kerma, 1.4 ± 1.4 Gy vs 2.1 ± 2.0 Gy; P = .02; dose area product, 147 ± 75 Gy â cm2 vs 208 ± 102 Gy â cm2; P = .006). One patient had died (1%) within 30 days. No differences were found in the major adverse events among the patients treated with infrarenal aortic vs iliac sealing zones (22% vs 18%; P = .63), including any spinal cord injury (13% vs 9%; P = .54) and grade 3 spinal cord injury (7% vs 7%; P = 1.0). The mean clinical follow-up was 24 ± 18 months. TIbE occurred in one patient in each group (P = 1.0). The 3-year freedom from TIbE and freedom from secondary intervention rate was 98% ± 2% and 67% ± 8% for the infrarenal aortic seal group and 97% ± 3% and 67% ± 8% for the iliac seal group, respectively (P = NS). Among the patients treated with infrarenal aortic sealing zones, the mean enlargement of the infrarenal aortic diameter was 5 ± 3.2 mm at 3 years. No late TIbE due to disease progression had developed in the infrarenal aorta. CONCLUSIONS: Infrarenal aortic and iliac artery seal zones are safe and effective during FB-EVAR, provided the patients have suitable segments. The use of the infrarenal aortic sealing zone had modest procedural advantages such as shorter endovascular and fluoroscopy times and lower radiation exposure. No differences were found in the clinical outcomes or development of TIbEs.

OBJECTIVE: In the present study, we defined the outcomes and effects of pregnancy in a cohort of women of childbearing age with acute aortic dissection (AAD). METHODS: We reviewed our database of AAD to identify all eligible female patients. Women aged <45 years were included. Data on pregnancy timing with respect to the occurrence of dissection, the demographic data, dissection extent, dissection treatment, dissection-related outcomes, overall maternal and fetal mortality, and genetic testing results were analyzed. RESULTS: A total of 62 women aged <45 years had presented to us with AAD from 1999 to 2017. Of the 62 women, 37 (60%) had had a history of pregnancy at AAD. Of these 37 patients, 10 (27%) had had a peripartum aortic dissection, defined as dissection during pregnancy or within 12 months postpartum. Of the 10 AADs, 5 were type A and 5 were type B. Three patients had presented with AAD during pregnancy (one in the second and two in the third trimester). Five patients (50%) had developed AAD in the immediate postpartum period (within 3 months) and two (20%) in the late postpartum period. For the immediate postpartum AADs (<3 months), four of the five patients delivered via cesarean section. Of these 10 peripartum AADs, 3 (30%) had occurred in patients with known Marfan syndrome. In-hospital mortality for those with peripartum AAD was 10% (1 of 10). Fetal mortality was 20% (2 of 10). CONCLUSIONS: The frequency of aortic dissection in women of childbearing age at our institution was low. However, pregnancy might increase the risk of those young women genetically predisposed to dissection events. From these data, this risk appears to be greatest in the immediate postpartum period, even for those who undergo cesarean section. Close clinical and radiographic surveillance is required for all women with suspected aortopathy, especially in the third trimester and early postpartum period.

PURPOSE: Common celiomesenteric trunk (CMT) is a rare anatomical variation that occurs in 0.5% to 3.4% of the general population. Its presence may complicate planning and implantation of fenestrated and branched stent-grafts because the wide diameter and short length of the CMT to its bifurcation does not allow sufficient sealing for placement of bridging stents. CASE REPORT: We report a patient with thoracoabdominal aortic aneurysm (TAAA) and CMT treated by fenestrated-branched endovascular aortic repair (FB-EVAR) using double kissing directional branches to incorporate the celiac axis and superior mesenteric artery. Pitfalls of stent design and implantation are outlined. CONCLUSION: Double kissing directional branches should be considered as an alternative to incorporate vessels with early bifurcation such as a CMT.

Carotid patch infection is a rare complication but one often associated with severe morbidity, including hemorrhage, stroke, cranial nerve injury, and mortality. We present a case of a gram-negative bacterial infection of a bovine pericardial carotid patch. Treatment ultimately required patch explantation and reconstruction with a femoral arterial interposition graft.

BACKGROUND: Thoracic outlet syndrome (TOS) results from compression of the neurovascular structures in the thoracic outlet. Decompression provides relief of TOS symptoms. However, little is known about long-term function and quality of life (QoL) from a patient's perspective. The purpose of this study was to evaluate surgical and QoL outcomes after surgical decompression of the thoracic outlet using a paraclavicular approach. METHODS: A prospectively maintained database was used to conduct a retrospective review of patients who underwent thoracic outlet decompression between August 2004 and August 2018. We excluded patients without complete follow-up data. Functional outcomes were assessed by the Derkash classification (poor, fair, good, excellent) using contingency table methods, and QoL was assessed by the 12-Item Short Form Health Survey (SF-12) using general linear models. SF-12 was scored by published criteria, and scale-specific and aggregate mental and physical health-related QoL scores were computed. Aggregate QoL scores range from 0 (terrible) to 100 (perfect). Secondary outcomes included mortality, complications, and duration of hospital stay. RESULTS: We performed 105 operations for TOS, and 100 patients with complete follow-up data were included in the study. Five patients were lost to follow-up. Median age was 35 (interquartile range, 24-47) years, and 58 (58%) were female. The median duration of hospital stay was 4 (interquartile range, 3-5.5) days. Of these patients, 46 had venous etiology, 8 arterial, 42 neurogenic, and 4 mixed vascular and neurogenic. Good or excellent Derkash results were reported in 77 (77%) patients, 46 of 54 (85%) of those with vascular TOS vs 31 of 46 (67%) of those with neurogenic etiology (P < .036). SF-12 score was obtained in 93 of 100 (93%) with a median duration from surgery of 6.1 (3.3-9.3) years. Patients with neurogenic TOS (NTOS) reported significantly lower aggregate mental health QoL than patients with vascular-only TOS (57 vs 59; P < .016). This effect persisted across the entire duration of follow-up and was unaffected by time from surgery (regression P for time = .509). In contrast, aggregate physical function QoL was unaffected by neurogenic etiology (P = .303), and all patients improved linearly with time (0.5 scale unit/y; P < .009). Three patients with incomplete relief of symptoms after paraclavicular decompression for NTOS underwent pectoralis minor decompression. There were no deaths or injuries to the long thoracic nerve. Complications included pleural effusion or hemothorax requiring evacuation (n = 6), neurapraxia (n = 6), and lymph leak (n = 2) treated with tube thoracostomy. CONCLUSIONS: NTOS is associated with significantly worse functional outcome assessed by the Derkash classification. NTOS also demonstrated worse composite mental health QoL, which did not improve over time. In contrast, composite physical health QoL improved linearly with time from surgery regardless of etiology of TOS.
