RESUMEN

BACKGROUND: Enhanced recovery after surgery pathways lead to improve perioperative outcomes for patients with vascular-related amputations; however, long-term data and functional outcomes are lacking. This study evaluated patients treated by the lower extremity amputation pathway (LEAP) and identified predictors of ambulation. METHODS: A retrospective review of LEAP patients who underwent major amputation from 2016 to 2022 for Wound, Ischemia, and foot Infection stage V disease was performed. LEAP patients were matched 1:1 with retrospective controls (NOLEAP) by hospital, need for guillotine amputation, and final amputation type (above knee vs below knee). The primary end point was the Medicare Functional Classification Level (K level) (functional classification of patients with amputations) at the last follow-up. RESULTS: We included 126 patients with vascular-related amputations (63 LEAP and 63 NOLEAP). Seventy-one percent of the patients were male and 49% were Hispanic with a mean state Area Deprivation Index of 9/10. There were no differences in baseline demographics or comorbidities. All patients had a K level of >0 (ambulatory) before amputation and an average Modified Frailty Index of 4. The median follow-up was 270 days (interquartile range, 84-1234 days) in the NOLEAP group and 369 days (interquartile range, 145-481 days) in the LEAP group. Compared with NOLEAP patients, LEAP patients were more likely to receive a prosthesis (86% vs 44%;P > .001). LEAP patients were more likely to have a K level of >0 (60% vs 25%; P = .003). On multivariable logistic regression, participation in LEAP increased the odds of a K level of >0 at follow-up by 5.8-fold (odds ratio, 5.8; 95% confidence interval, 2.5-13.6). Patients with a K level of >0 had significantly higher survival at 4 years (93% vs 59%; P = .001). In a Cox proportional hazards model, adjusted for demographics, comorbidities and amputation level, a K level of >0 at follow-up was associated with an 88% decrease in the risk of mortality compared with a K level of 0. CONCLUSIONS: LEAP leads to improved ambulation with a prosthesis in a socioeconomically disadvantaged and frail patient population. Patients with a K level of >0 (ambulatory) have significantly improved mortality.

RESUMEN

OBJECTIVE: Clopidogrel resistance testing is not routine prior to Transcarotid Artery Revascularization (TCAR) and resistance rates are not well described in this setting, despite frequent use of periprocedural clopidogrel. We compared two resistance testing modalities to determine the relationship between resistance and stent outcomes. METHODS: Consecutive patients undergoing TCAR at three institutions were retrospectively identified. Clopidogrel-resistance testing results and outcomes were described. RESULTS: A total of 210 patients underwent TCAR from 2018-2022. 154 (73%) were on dual antiplatelet therapy (DAPT) for at least 7 days prior to TCAR. Twenty-nine patients were not on DAPT due to therapeutic anticoagulation and most (38/56, 68%) received a loading dose of a second antiplatelet the day of surgery. Twenty-five patients (11.9%) experienced stent thrombosis within 30 days. Patients not on DAPT for at least 7 days prior to surgery were more prone to stent thrombosis (16.7% vs 10.4%, p=.164). Over half (133/210, 63%) of patients underwent resistance testing, 25 with thromboelastogram with platelet mapping (TEG-PM), 103 with VerifyNow P2Y12 platelet reactivity assay, and 5 with both. Prevalence of Clopidogrel resistance among tested patients was 41%. In patients tested using both TEG-PM and VerifyNow, agreement was poor (Cohen's Kappa -0.05). Among patients with resistance, 12 (22%) experienced stent thrombosis. Comparatively, 8 (10%) patients without resistance developed thrombosis (p=.021). VerifyNow P2Y12 platelet reactivity assay correctly predicted Clopidogrel-resistance more accurately than TEG-PM (70% versus 40%, p=.025) and had sensitivity of 56% and specificity of 73% for stent thrombosis. CONCLUSION: Our multi-institutional cohort confirms a high rate of Clopidogrel resistance in patients undergoing TCAR, with higher acute stent thrombosis rates noted in patients with resistance. VerifyNow P2Y12 platelet reactivity assays more reliably predict Clopidogrel resistance than TEG-PM.

RESUMEN

BACKGROUND: The Lower Extremity Amputation Protocol (LEAP) is a multidisciplinary enhanced recovery after surgery pathway for vascular amputees. The objective of this study was to examine feasibility and outcomes of community-wide implementation of LEAP. METHODS: LEAP was implemented at three safety net hospitals for patients with peripheral artery disease or diabetes requiring major lower extremity amputation. Patients who underwent LEAP (LEAP) were matched 1:1 with retrospective controls (NOLEAP) on hospital location, need for initial guillotine amputation, and final amputation type (above- vs below-knee). Primary endpoint was postoperative hospital length of stay (PO-LOS). RESULTS: A total of 126 amputees (63 LEAP and 63 NOLEAP) were included with no difference between baseline demographics and co-morbidities between the groups. After matching, both groups had the same prevalence of amputation level (76% below-knee vs 24% above-knee). LEAP patients had shorter duration of postamputation bed rest (P = .003) and were more likely to receive limb protectors (100% vs 40%; P ≤ .001), prosthetic counseling (100% vs 14%; P ≤ .001), perioperative nerve blocks (75% vs 25%; P ≤ .001), and postoperative gabapentin (79% vs 50%; P ≤ .001). Compared with NOLEAP, LEAP patients were more likely to be discharged to an acute rehabilitation facility (70% vs 44%; P = .009) and less likely to be discharged to a skilled nursing facility (14% vs 35%; P = .009). The median PO-LOS for the overall cohort was 4 days. LEAP patients had a shorter median PO-LOS (3 [interquartile range, 2-5] vs 5 [interquartile range, 4-9] days; P < .001). On multivariable logistic regression, LEAP decreased the odds of a PO-LOS of ≥4 days by 77% (odds ratio, 0.23; 95% confidence interval, 0.09-0.63). Overall, LEAP patients were significantly less likely to have phantom limb pain (5% vs 21%; P = .02) and were more likely to receive a prosthesis (81% vs 40%; P ≤ .001). In a multivariable Cox proportional hazards model, LEAP was associated with an 84% reduction in time to receipt of prosthesis (hazard ratio, 0.16; 95% confidence interval, 0.085-0.303; P < .001). CONCLUSIONS: Community wide implementation of LEAP significantly improved outcomes for vascular amputees demonstrating that utilization of core ERAS principles in vascular patients leads to decreased PO-LOS and improved pain control. LEAP also affords this socioeconomically disadvantaged population a greater opportunity to receive a prosthesis and return to the community as a functional ambulator.

RESUMEN

BACKGROUND: Carotid endarterectomy (CEA) has demonstrated superior results in stroke risk reduction for patients with symptomatic and asymptomatic high-grade carotid stenosis. However, this benefit has long been questioned for the elderly and high-risk populations. In the present study, we aimed to provide high-volume, single-institution data with long-term follow-up examining the risk factors for postoperative stroke and stroke-free survival stratified by age for asymptomatic and symptomatic patients undergoing CEA. METHODS: A single-institution retrospective review of 840 consecutive patients who had undergone CEA from 2011 to 2018 was performed, inclusive of both symptomatic and asymptomatic operative indications. The primary end point was perioperative stroke within 30 days of surgery. The secondary end points were late stroke, death, and myocardial infarction. Patients aged >80 years were compared with those aged <80 years to examine freedom from stroke and death. Statistically significant differences were defined as those with P < .05. RESULTS: A total of 840 patients were evaluated with a median follow-up of 416 ± 1244 days. Of the 840 patients, 499 (59%) were men, and 604 (72%) were White. The mean age was 72 ± 9 years, with 202 (24%) aged ≥80 years. CEA was performed for symptomatic disease in 305 patients (36%), of whom 143 (47%) had had strokes and 162 (53%) had had transient ischemic attacks. The overall 30-day postoperative stroke rate was 1.0% (eight patients; 0.6% for asymptomatic and 1.6% for symptomatic; P = .147). Compared with younger patients, octogenarians had had a similar stroke rate after CEA (1.5% vs 0.8%; P = .407). Hispanic race was an independent risk factor for postoperative stroke. White race and preoperative statin use both appeared to be protective. Kaplan-Meier survival curves demonstrated decreased a 5-year stroke-free survival in patients aged ≥80 years (P = .031). However, overall, the estimated 5-year survival was similar to the U.S. general population across both age groups. CONCLUSIONS: CEA for octogenarians is safe and effective for both symptomatic and asymptomatic populations with excellent 30-day outcomes and long-term survival mirroring that of the general population.

RESUMEN

OBJECTIVE: Aberrant subclavian artery (ASA) and Kommerell's diverticulum (KD) are rare vascular anomalies that may be associated with lifestyle-limiting and life-threatening complications. The aim of this study is to report contemporary outcomes after invasive treatment of ASA/KD using a large international dataset. METHODS: Patients who underwent treatment for ASA/KD (2000-2020) were identified through the Vascular Low Frequency Disease Consortium, a multi-institutional collaboration to investigate uncommon vascular disorders. We report the early and mid-term clinical outcomes including stroke and mortality, technical success, and other operative outcomes including reintervention rates, patency, and endoleak. RESULTS: Overall, 285 patients were identified during the study period. The mean patient age was 57 years; 47% were female and 68% presented with symptoms. A right-sided arch was present in 23%. The mean KD diameter was 47.4 mm (range, 13.0-108.0 mm). The most common indication for treatment was symptoms (59%), followed by aneurysm size (38%). The most common symptom reported was dysphagia (44%). A ruptured KD was treated in 4.2% of cases, with a mean diameter of 43.9 mm (range, 18.0-100.0 mm). An open procedure was performed in 101 cases (36%); the most common approach was ASA ligation with subclavian transposition. An endovascular or hybrid approach was performed in 184 patients (64%); the most common approach was thoracic endograft and carotid-subclavian bypass. A staged operative strategy was employed more often than single setting repair (55% vs 45%). Compared with endovascular or hybrid approach, those in the open procedure group were more likely to be younger (49 years vs 61 years; P < .0001), female (64% vs 36%; P < .0001), and symptomatic (85% vs 59%; P < .0001). Complete or partial symptomatic relief at 1 year after intervention was 82.6%. There was no association between modality of treatment and symptom relief (open 87.2% vs endovascular or hybrid approach 78.9%; P = .13). After the intervention, 11 subclavian occlusions (4.5%) occurred; 3 were successfully thrombectomized resulting in a primary and secondary patency of 95% and 96%, respectively, at a median follow-up of 39 months. Among the 33 reinterventions (12%), the majority were performed for endoleak (36%), and more reinterventions occurred in the endovascular or hybrid approach than open procedure group (15% vs 6%; P = .02). The overall survival rate was 87.3% at a median follow-up of 41 months. The 30-day stroke and death rates were 4.2% and 4.9%, respectively. Urgent or emergent presentation was independently associated with increased risk of 30-day mortality (odds ratio [OR], 19.8; 95% confidence interval [CI], 3.3-116.6), overall mortality (OR, 3.6; 95% CI, 1.2-11.2) and intraoperative complications (OR, 8.3; 95% CI, 2.8-25.1). Females had a higher risk of reintervention (OR, 2.6; 95% CI, 1.0-6.5). At an aneurysm size of 44.4 mm, receiver operator characteristic curve analysis suggested that 60% of patients would have symptoms. CONCLUSIONS: Treatment of ASA/KD can be performed safely with low rates of mortality, stroke and reintervention and high rates of symptomatic relief, regardless of the repair strategy. Symptomatic and urgent operations were associated with worse outcomes in general, and female gender was associated with a higher likelihood of reintervention. Given the worse overall outcomes when symptomatic and the inherent risk of rupture, consideration of repair at 40 mm is reasonable in most patients. ASA/KD can be repaired in asymptomatic patients with excellent outcomes and young healthy patients may be considered better candidates for open approaches versus endovascular or hybrid modalities, given the lower likelihood of reintervention and lower early mortality rate.

RESUMEN

BACKGROUND: Aberrant subclavian artery (ASA) with or without Kommerell's diverticulum (KD) is a rare anatomic aortic arch anomaly that can cause dysphagia and/or life-threatening rupture. The objective of this study is to compare outcomes of ASA/KD repair in patients with a left versus right aortic arch. METHODS: Using the Vascular Low Frequency Disease Consortium methodology, a retrospective review was performed of patients ≥18 years old with surgical treatment of ASA/KD from 2000 to 2020 at 20 institutions. RESULTS: 288 patients with ASA with or without KD were identified; 222 left-sided aortic arch (LAA), and 66 right-sided aortic arch (RAA). Mean age at repair was younger in LAA 54 vs. 58 years (P = 0.06). Patients in RAA were more likely to undergo repair due to symptoms (72.7% vs. 55.9%, P = 0.01), and more likely to present with dysphagia (57.6% vs. 39.1%, P < 0.01). The hybrid open/endovascular approach was the most common repair type in both groups. Rates of intraoperative complications, death within 30 days, return to the operating room, symptom relief and endoleaks were not significantly different. For patients with symptom status follow-up data, in LAA, 61.7% had complete relief, 34.0% had partial relief and 4.3% had no change. In RAA, 60.7% had complete relief, 34.4% had partial relief and 4.9% had no change. CONCLUSIONS: In patients with ASA/KD, RAA patients were less common than LAA, presented more frequently with dysphagia, had symptoms as an indication for intervention, and underwent treatment at a younger age. Open, endovascular and hybrid repair approaches appear equally effective, regardless of arch laterality.

RESUMEN

OBJECTIVE: Atherectomy has become increasingly used as an endovascular treatment of lower extremity atherosclerotic disease in the United States. However, concerns and controversies about its indications and outcomes exist. The goal of the present systematic review and meta-analysis was to investigate the outcomes and complications related to atherectomy to treat femoropopliteal atherosclerotic disease. METHODS: A systematic review in accordance with the recommendations from the PRISMA (preferred reporting items for systematic reviews and meta-analyses) statement was performed. Four major scientific repositories (MEDLINE, Embase, the Cochrane Library, and Thompson Web of Sciences) were queried from their inception to April 5, 2020. We reviewed and entered the data in a dedicated dataset. The outcomes included the patency rates, clinical and hemodynamic improvement, and morbidity and mortality associated with atherectomy interventions. RESULTS: Twenty-four studies encompassing 1900 patients met the inclusion criteria for the present study. Of the 1900 patients, 74.3% had presented with Rutherford class 1 to 3 and 25.7% presented with Rutherford class 4 to 6; 1445 patients had undergone atherectomy, and 455 patients had been treated without atherectomy. The atherectomy group had undergone directional atherectomy (n = 851), rotational atherectomy (n = 851), laser atherectomy (n = 201), and orbital atherectomy (n = 78). Most of these patients had also received adjunct treatments, which varied across the studies and included a combination of stenting, balloon angioplasty, or drug-coated balloon angioplasty. Technical success was achieved in 92.3% of the cases. Distal embolization, vessel perforation, and dissection occurred in 3.4%, 1.9%, and 4% of the cases, respectively. The initial patency was 95.4%. At the 12-month median follow-up, the primary patency was 72.6%. The ankle brachial index had improved from a preoperative mean of 0.6 to a postoperative mean of 0.84. The incidence of major amputation and mortality during the follow-up period was 2.2% and 3.4%, respectively. CONCLUSIONS: The results from our review of the reported data suggest that femoropopliteal atherectomy can be completed safely, modestly improving the ankle brachial index and maintaining the 1-year patency in nearly three of four patients. However, these findings were based on heterogeneous studies that skewed the generalizable conclusions about atherectomy's efficacy. Atherectomy places a high cost burden on the healthcare system and is used in the United States at a higher rate than in other countries. Our review of the literature did not demonstrate clear atherectomy superiority to alternatives that would warrant the pervasive and increasing use of this costly technology. Future work should focus on developing high-quality randomized controlled trials to determine the specific patient and lesion characteristics for which atherectomy can add value.

RESUMEN

BACKGROUND: We queried the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database to review outcomes of acute limb ischemia (ALI) patients following open surgical intervention for ALI. METHODS: A previously validated tool was used to identify ALI patients in NSQIP undergoing open surgical revascularization from 2012 to 2017. Multivariable analysis was performed for the primary outcome of reoperation and secondary outcome of readmission and infection. RESULTS: A total of 2,878 ALI patients underwent open revascularization; 35.7% were transfers from another acute care hospital. A total of 13.8% required reoperation and 7.9% required readmission within 30 days. A total of 32% of reoperations were recurrent revascularization, representing 4.4% of all ALI patients. A total of 58.7% of patients were female and either overweight or obese. Younger age (odds ratio OR 0.991 [0.984-0.999], P = 0.02), underweight patients (OR 1.159 [0.667-2.01], P = 0.05), pre-operative steroid use (OR 1.61 [1.07-2.41], P = 0.02), and perioperative transfusion (OR 2.02 [1.04-3.95], P = 0.04) predicted reoperations. CONCLUSIONS: This registry series demonstrates all-cause ALI patients are a different population than PAD with different risk factors. Despite being a time-critical condition, ALI has higher interhospital transfer rates than ACS or ruptured aneurysm. Following open revascularization, ALI outcomes are worse than ACS but better than ruptured AAA. These outcomes do not appear related to patient factors in contrast to revascularization for chronic PAD.

RESUMEN

OBJECTIVE: Traumatic popliteal artery injuries are associated with the greatest risk of limb loss of all peripheral vascular injuries, with amputation rates of 10% to 15%. The purpose of the present study was to examine the outcomes of patients who had undergone operative repair for traumatic popliteal arterial injuries and identify the factors independently associated with limb loss. METHODS: A multi-institutional retrospective review of all patients with traumatic popliteal artery injuries from 2007 to 2018 was performed. All the patients who had undergone operative repair of popliteal arterial injuries were included in the present analysis. The patients who had required a major lower extremity amputation (transtibial or transfemoral) were compared with those with successful limb salvage at the last follow-up. The significant predictors (P < .05) for amputation on univariate analysis were included in a multivariable analysis. RESULTS: A total of 302 patients from 11 institutions were included in the present analysis. The median age was 32 years (interquartile range, 21-40 years), and 79% were men. The median follow-up was 72 days (interquartile range, 20-366 days). The overall major amputation rate was 13%. Primary repair had been performed in 17% of patients, patch repair in 2%, and interposition or bypass in 81%. One patient had undergone endovascular repair with stenting. The overall 1-year primary patency was 89%. Of the patients who had lost primary patency, 46% ultimately required major amputation. Early loss (within 30 days postoperatively) of primary patency was five times more frequent for the patients who had subsequently required amputation. On multivariate regression, the significant perioperative factors independently associated with major amputation included the initial POPSAVEIT (popliteal scoring assessment for vascular extremity injury in trauma) score, loss of primary patency, absence of detectable immediate postoperative pedal Doppler signals, and lack of postoperative antiplatelet therapy. Concomitant popliteal vein injury, popliteal injury location (P1, P2, P3), injury severity score, and tibial vs popliteal distal bypass target were not independently associated with amputation. CONCLUSIONS: Traumatic popliteal artery injuries are associated with a significant rate of major amputation. The preoperative POPSAVEIT score remained independently associated with amputation after including the perioperative factors. The lack of postoperative pedal Doppler signals and loss of primary patency were highly associated with major amputation. The use of postoperative antiplatelet therapy was inversely associated with amputation, perhaps indicating a protective effect.

RESUMEN

OBJECTIVE: Traumatic popliteal vascular injuries are associated with the highest risk of limb loss of all peripheral vascular injuries. A method to evaluate the predictors of amputation is needed because previous scores could not be validated. In the present study, we aimed to provide a simplified scoring system (POPSAVEIT [popliteal scoring assessment for vascular extremity injuries in trauma]) that could be used preoperatively to risk stratify patients with traumatic popliteal vascular injuries for amputation. METHODS: A review of patients sustaining traumatic popliteal artery injuries was performed. Patients requiring amputation were compared with those with limb salvage at the last follow-up. Of these patients, 80% were randomly assigned to a training group for score generation and 20% to a testing group for validation. Significant predictors of amputation (P < .1) on univariate analysis were included in a multivariable analysis. Those with P < .05 on multivariable analysis were assigned points according to the relative value of their odds ratios (ORs). Receiver operating characteristic curves were generated to determine low- vs high-risk scores. An area under the curve of >0.65 was considered adequate for validation. RESULTS: A total of 355 patients were included, with an overall amputation rate of 16%. On multivariate regression analysis, the risk factors independently associated with amputation in the final model were as follows: systolic blood pressure <90 mm Hg (OR, 3.2; P = .027; 1 point), associated orthopedic injury (OR, 4.9; P = .014; 2 points), and a lack of preoperative pedal Doppler signals (OR, 5.5; P = .002; 2 points [or 1 point for a lack of palpable pedal pulses if Doppler signal data were unavailable]). A score of ≥3 was found to maximize the sensitivity (85%) and specificity (49%) for a high risk of amputation. The receiver operating characteristic curve for the validation group had an area under the curve of 0.750, meeting the threshold for score validation. CONCLUSIONS: The POPSAVEIT score provides a simple and practical method to effectively stratify patients preoperatively into low- and high-risk major amputation categories.

RESUMEN

PURPOSE: The treatment of thoracoabdominal aortic aneurysm has largely shifted to endovascular techniques. However, severe iliofemoral arterial disease often presents a challenge during these interventions. As a result, iliac conduits have been introduced to facilitate aortic endovascular therapy. The goal of the current study was to gauge utilization and to analyze iliac artery conduit outcomes to facilitate endovascular therapy to treat aortic pathologies. MATERIALS AND METHODS: A meta-analysis of 14 studies was conducted with the use of random effects modeling. The incidence of periprocedural adverse events was gauged based on iliac conduit vs nonconduit cases and planned vs unplanned iliac conduit placement. Outcomes of interest included length of hospital stay, morbidity and mortality associated to conduits, and all-cause mortality. RESULTS: Iliac conduits, either open or endo-conduits, were utilized in 17% (95% CI: 9%-27%) of 16,855 cases, with technical successful rate of 94% (95% CI: 80%-100%). Periprocedural complications occurred in 32% (95% CI: 22%-42%) of the cases, with overall bleeding complication rate being 10% (95% CI: 5%-16%). Female patients, positive history for smoking, pulmonary disease, and peripheral artery disease at baseline were associated with more frequent utilization of iliac conduits. Conduit use was associated with longer hospitalization, higher periprocedural all-cause mortality (OR: 2.85; 95% CI: 1.75-4.64; p<0.001), and bleeding complication rate (OR: 2.38; 95% CI: 1.58-3.58; p<0.001). Sensitivity analysis among conduit cases showed that planned conduits were associated with fewer periprocedural complications compared to unplanned conduits (OR: 0.38; 95% CI: 0.20-0.73; p=0.004). CONCLUSION: Iliac conduit placement is a feasible strategy, associated with high technical success to facilitate complex aortic endovascular repair. However, periprocedural adverse event rate, including bleeding complications is not negligible. All-cause mortality and morbidity rates among cases that require iliac conduits should be strongly considered during clinical decision making. High-quality comparative analyses between iliac conduit vs nonconduit cases and between several types of iliac conduit grafts aiming at facilitating endovascular aortic repair are still needed to determine the best strategy to address challenging iliac artery accesses.

RESUMEN

We report the case of a massive pulmonary embolism with intraoperative cardiac arrest in a 48-year-old male during routine surgical tibial bypass successfully managed by catheter-based interventions. Our experience supports the trending shift in pulmonary embolism therapy guidelines to include endovascular approaches and emphasizes the need for vascular surgeons to adapt their training protocols.

RESUMEN

BACKGROUND: Acute limb ischemia (ALI) carries significant overall morbidity and mortality. Pregnant and postpartum women are physiologically hypercoagulable, but little is known about the impact of ALI in this cohort of patients. The goal of this systematic review was to gather available data on diagnosis and treatment of ALI during pregnancy and the postpartum period. METHODS: A systematic review of studies on patients with ALI during pregnancy and the puerperium was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Three databases including PubMed MEDLINE, Embase, and Cochrane Library were queried. Manuscripts that provided data on diagnosis and treatment of ALI in pregnant and postpartum patients were included regardless of language or study design. Outcomes of interest included type of treatment for ALI (open and endovascular), morbidity, and mortality. RESULTS: Fourteen manuscripts of 6222 references were included with a total of 14 patients. The median age of patients was 31.5 years. Embolism, present in eight (57%) patients, was slightly more common than thrombosis. All patients had a pregnancy complication or concomitant medical condition that might have predisposed to arterial occlusion either directly or indirectly by leading to iatrogenic arterial injury; peripartum cardiomyopathy, the most common, occurred in six (43%) patients. Open surgery was the preferred treatment option in 11 (79%) patients, followed by anticoagulation alone. No endovascular procedures were described. One patient underwent major amputation on presentation, and an additional patient required major amputation for recurrent ALI. No deaths occurred. Twelve (86%) patients had complete recovery with no other ALI-associated sequelae. CONCLUSIONS: ALI is rare in pregnant and postpartum women despite their transient physiologic hypercoagulability and is almost uniformly associated with pregnancy complications. Open surgical revascularization or anticoagulation alone appears to have acceptable outcomes as most patients present with embolism or thrombosis without underlying systemic arterial disease.

RESUMEN

Ruptured thoracoabdominal aneurysms (rTAAAs) are rare and carry a significant rate of morbidity and mortality. Aortocaval fistula secondary to rTAAA is even more infrequent. We describe an urgent and staged endovascular treatment of a ruptured extent III thoracoabdominal aortic aneurysm with an aortocaval fistula by performing vena cava stenting to treat aortocaval fistula as a damage control maneuver prior to transfer and subsequent TAAA repair with a physician-modified endograft at a quaternary level hospital.

RESUMEN

BACKGROUND: Iliac artery anatomy can have a dramatic impact on the success of endovascular complex aortic aneurysm (CAA) procedures as endograft delivery systems need to be advanced and manipulated through these access vessels. The aim of this study was to evaluate the outcomes of iliac artery conduits with emphasizes on open vs endovascular conduits performed to facilitate CAA endovascular repair. METHODS: All patients who had open or endovascular iliac conduits prior to endovascular CAA repair to treat thoracoabdominal, juxtarenal, or suprarenal aneurysms at the University of Colorado Hospital from January 2009 through January 2019 were included. Patients who presented with symptomatic or ruptured aortic aneurysms were excluded. Outcomes of interest included postoperative complications and mortality in patients undergoing iliac conduits. RESULTS: Twenty-seven patients with a total of 42 conduits were included in the study. The majority of patients (N = 15, 56%) were female and the average age was 72 ± 9 years. The calculated VQI cardiac index was .6% (range, .3%-.8%). Eighteen (43%) endovascular and 24 (57%) open iliac conduits were performed during the study period. Thirty (71%) conduits were performed in a staged fashion, while 12 (29%) were performed at the same time as endovascular CAA repair. The mean time between conduit and definitive aneurysm repair surgery was 130 ± 68 days in the endovascular and 107 ± 79 days in the open groups (P = .87). No aneurysm rupture occurred during the staging period in either group. The median follow-up for the entire cohort was 18 ± 22 months. The median length of hospital stay for patients undergoing endovascular and open ICs was 6 (ranging, 1-28 days) and 7 days (ranging, 3-18 days), respectively. Patients undergoing open conduits had significantly more complications than those undergoing endovascular conduit (endoconduit) creation. A total of 4 (15%) patients died within 30 days after aneurysm repair. Out of 23 survivors, 18 (78%) patients were discharged home, 4 (18%) patients were discharged to a skilled nursing facility, and 1 (4%) patient was discharged to an acute rehabilitation facility. No mortality difference based on type of conduit was found. CONCLUSIONS: Overall complication rate associated with creation of open iliac artery conduits is not negligible. Endoconduits, which carry less morbidity than open conduits, are preferred as a first-line adjunctive access procedure to facilitate complex endovascular aortic aneurysm repair.

RESUMEN

BACKGROUND: Carotid endarterectomy (CEA) remains a safe and durable operation for both symptomatic and asymptomatic carotid stenosis, however conflicting evidence exists on the benefit of patch angioplasty and its effects on post-operative outcomes. METHODS: A retrospective review of all patients undergoing CEA from 2011 to 2018 was performed. RESULTS: Of 851 patients, primary closure was performed in 277 (33%). Patients with primary closure were older (74 vs 72, p = 0.001), symptomatic (39% vs 34%, p = 0.024), and male (69% vs 31% p < 0.001), with a higher incidence of diabetes mellitus (47% vs 39%, p = 0.046) and ESRD (4% vs 2%, p = 0.015). Restenosis rates were similar (7% vs 8%, p = 0.67). Operative time was shorter for primary closure (87 ± 28 vs 102 ± 26 min, p < 0.001). There were no differences in 30-day ipsilateral stroke rates (1% vs 1%, p = 0.51) or stroke-free survival. CONCLUSIONS: Primary arterial closure is safe and expeditious in appropriately selected high-risk patients.

RESUMEN

BACKGROUND: Injuries to the axillosubclavian arteries are rare, comprising 5% of all extremity trauma. This study aims to examine contemporary outcomes of traumatic axillosubclavian injuries. METHODS: A retrospective review was performed on patients admitted with innominate, subclavian, and/or axillary artery injuries to a level 1 trauma center from 2011 to 2021. Patients undergoing endovascular repair were compared to those with open repair. RESULTS: Thirty two patients met inclusion criteria. Injuries were approached open in 22 (59%) cases and endovascular in 10 (27%). There was no difference in 30-day mortality or hospital length of stay between endovascular and open repair. Endovascular repairs had shorter operative times (1.9 vs 3.1 h, p = 0.009) and lower blood loss (72 vs 1662 mL, p < 0.001). CONCLUSIONS: Endovascular repair of axillosubclavian arterial injuries demonstrate similar outcomes to open repair. Significantly shorter operative times and lower blood loss suggest potential decreased morbidity.

RESUMEN

OBJECTIVE: Chronic venous insufficiency (CVI) affects >40% of the U.S. population; thus, intervention for symptomatic venous disease comprises a large portion of many vascular practices. The treatment of superficial CVI has evolved from open surgical treatment to minimally invasive endovenous closure, including both thermal and nonthermal techniques. Thrombotic complications of thermal ablation have been well reported, with an overall complication rate of <2%. However, a paucity of high-powered, real-world data is available on the thrombotic outcomes of nonthermal techniques. In the present study, we compared the incidence of endovenous heat-induced thrombosis (EHIT) and endovenous glue-induced thrombosis (EGIT) in a large cohort of patients with CVI. METHODS: A retrospective review was conducted at two tertiary-level institutions of patients who had undergone superficial endovenous ablation from 2018 to 2021. The patient demographics, comorbidities, and periprocedural outcomes were collected through medical record review. A Caprini risk assessment model score was assigned using the information available from the electronic medical records. The patients were categorized by procedure type (ClosureFast [Medtronic Inc, Minneapolis, MN] radiofrequency ablation [RFA] vs VenaSeal [Medtronic Inc] cyanoacrylate glue closure [CAG]). The primary end point was the incidence of EHIT or EGIT. The secondary end point was the incidence of deep vein thrombosis and/or pulmonary embolism. RESULTS: A total of 803 patients had undergone 1096 procedures during the study period. Their mean age was 62 ± 15 years, and 67% were women. Of the 1096 procedures, 700 were RFA and 396 were CAG procedures, with a combined closure rate of 98% by postprocedure duplex ultrasound at 7 days. The average Caprini score was 5.2 ± 1.8 (RFA, 5.0; vs CAG, 5.4; P < .001). The incidence of EHIT and EGIT was 1.9% and 1.3%, respectively (P = .57). The deep vein thrombosis rate was 0.1% in the RFA cohort and 0.3% in the CAG cohort (P = .81). A comparative analysis of thermal vs nonthermal techniques was performed. A univariate analysis of the risk factors for EHIT and EGIT revealed no significant factors predisposing to thrombotic events. CONCLUSIONS: The results from the present study have demonstrated the safety of RFA and CAG closure techniques for CVI, with lower thrombotic rates than previously reported. Further work might help to identify how these results can be achieved across all venous ablative techniques for CVI, even for patient populations with advanced venous disease and possibly a greater than average risk of thrombotic events.

RESUMEN

Vascular patients, an inherently older, frail population, account for >80% of major lower extremity amputations (transtibial or transfemoral) in the United States. Retrospective data have shown that early physical therapy and discharge to an acute rehabilitation facility decreases the postoperative length of stay (LOS) and expedites ambulation. In the present study, we sought to determine whether patients treated with the lower extremity amputation protocol (LEAP) will have improved outcomes. We performed a nonrandomized prospective study of vascular patients undergoing an amputation from January 2019 to February 2020. Patients who were nonambulatory or had undergone a previous contralateral major amputation were excluded. LEAP is a multidisciplinary team approach to the perioperative care of amputees using an outlined protocol. The prospective patients were compared with historic controls treated before the initiation of LEAP (January 2016 to December 2018). The primary outcomes included the postoperative LOS, time to receipt of a prosthesis, and time to ambulation. Of the 141 included patients, 130 were in the retrospective group and 11 in the LEAP group. The demographics and comorbidities were similar. All 11 LEAP patients had undergone a below-the-knee amputation, with 1 requiring revision to an above-the-knee amputation. Of the 130 retrospective patients, 122 (94%) had undergone a below-the-knee amputation, with 1 requiring revision to an above-the-knee amputation. The LEAP patients were more likely to be discharged to acute rehabilitation (100% vs 27%; P < .001), receive a prosthesis (100% vs 45%; P < .001), and ambulate with the prosthesis (100% vs 43%; P < .001). The LEAP patients had received physical therapy 2 days sooner than had the retrospective controls (P = .006) with a shorter postoperative LOS (3 days vs 6 days; P < .001). Of the patients who had received their prosthesis, the LEAP patients had received their prosthesis, on average, 2 months sooner than had the retrospective cohort (81 ± 39 days vs 137 ± 97 days, respectively; P = .002) and had ambulated with their prosthesis sooner (86 ± 53 days vs 146 ± 104 days, respectively; P = .002). No differences were found in the incidence of surgical site complications or unplanned readmissions between the two groups. The results from the present pilot study have demonstrated that the use of LEAP can significantly decrease postoperative LOS and expedite the time to independent ambulation with a prosthesis for vascular patients undergoing a major lower extremity amputation. These findings suggest a powerful ability to bridge the healthcare gap for this high-risk, underserved, and ethnically diverse population using a disease-specific standardized protocol.

RESUMEN

BACKGROUND: Penetrating carotid injuries are associated with an up to 20% risk of stroke. This study evaluated patients in the American Association for Surgery of Trauma PROspective Observational Vascular Injury Trial, with the aim of determining factors associated with stroke and stroke or death. METHODS: Penetrating extracranial carotid injuries in the American Association for Surgery of Trauma PROspective Observational Vascular Injury Trial registry from 2012 to 2020 were queried. Isolated external carotid injuries were excluded. Patients with documented postinjury in-hospital stroke were compared with those without. Significant predictors (p < 0.1) for stroke and stroke or death on univariate analysis were included in multivariate analyses. RESULTS: One hundred two patients from 17 institutions were included. Mean age was 35 ± 18 years, and 80% were male. Average Glasgow Coma Scale (GCS) score on presentation was 9 ± 5, with an Injury Severity Score [ISS] of 22 ± 13. Operative management occurred in 51% of patients who were significantly more hypotensive (systolic blood pressure: 109 vs. 131 mm Hg; p = 0.015) with a lower initial pH (7.17 vs. 7.31; p = 0.001) and presented with hard signs of vascular injury (74% vs. 26%; p < 0.001). Overall stroke rate was 17% (23% operative vs. 10% nonoperative, p = 0.076). Rate of stroke or death was 27% (64% operative and 36% nonoperative). On multivariate analysis, lower GCS (p = 0.05) and completion angiography (p = 0.04) were associated with stroke. Likewise lower GCS (p = 0.015) and ISS (p = 0.04) were associated with stroke or death. CONCLUSION: Penetrating carotid trauma undergoing operative management had a stroke rate of 23%. Low GCS on arrival and need for completion angiography are independently associated with postinjury in-hospital stroke, whereas low GCS on arrival and ISS were associated with stroke or death. The ideal treatment strategy remains elusive, thus a dedicated multicenter study may help to achieve higher fidelity data on this rare but devastating injury. LEVEL OF EVIDENCE: Prognostic and Epidemiological, Level III.
