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.

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.

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.

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.

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.

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.

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.

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.

Endovenous ablation has become the preferred means to treat superficial venous insufficiency. Ablative technologies have evolved to include a variety of both thermal and non-thermal techniques. The reported thrombotic complications of endovenous heat induced thrombosis (EHIT) and deep venous thrombosis (DVT) associated with thermal techniques are low (<2% overall). However, the limited data on newer non-thermal technologies suggest these modalities may have thrombotic complication rates upwards of 6%. Additionally, the pathophysiology of thrombotic events related to mechanochemical ablative techniques may differ from EHIT, and thus, may have different implications for management. Described is a case report of a stroke after cyanoacrylate ablation of the great saphenous vein, and a review of the current literature reporting the thrombotic complications associated with current thermal and non-thermal techniques. There exists a need for high-volume studies on newer ablative techniques to fully understand their associated thrombotic complications. This review highlights the need for a comprehensive classification system and standard treatment algorithm encompassing of thrombotic complications associated with both thermal and non-thermal ablative techniques.

BACKGROUND: Open pelvic fracture, caused by a blunt mechanism, is an uncommon injury with a high mortality rate. In 2008, evidence-based algorithm for managing pelvic fractures in unstable patients was published by the Western Trauma Association (WTA). The use of massive transfusion protocols has become widespread as has the availability and use of pelvic angiography. The purpose of this study was to evaluate the outcome of open pelvic fractures in association with related advances in trauma care. METHODS: A retrospective review was performed, at an American College of Surgeon verified level I trauma center, of patients with blunt open pelvic fractures from January 2010 to April 2016. The WTA algorithm, including massive transfusion protocol, and pelvic angiography were uniformly used. Data collected included injury severity score, demographic data, transfusion requirements, use of pelvic angiography, length of stay, and disposition. Data were compared with a similar study from 2005. RESULTS: During the study period, 1505 patients with pelvic fractures were analyzed; 87 (6%) patients had open pelvic fractures. Of these, 25 were from blunt mechanisms and made up the study population. Patients in both studies had similar injury severity scores, ages, Glasgow Coma Scale, and gender distributions. Use of angiography was higher (44% vs. 16%; P=0.011) and mortality was lower (16% vs. 45%; P=0.014) than in the 2005 study. CONCLUSIONS: Changes in trauma care for patients with open blunt pelvic fracture include the use of an evidence-based algorithm, massive transfusion protocols and increased use of angioembolization. Mortality for open pelvic fractures has decreased with these advances. LEVEL OF EVIDENCE: Level IV.
RESUMEN
BACKGROUND: Recent studies have suggested higher complication and conversion to open rates for nighttime laparoscopic cholecystectomy (LC) and recommend against the practice. We hypothesize that patients undergoing night LC for acute cholecystitis have decreased hospital length of stay and cost with no difference in complication and conversion rates. METHODS: A retrospective review of patients with acute cholecystitis who underwent LC from October 2011 through June 2015 was performed. Complication rates, length of stay, and cost of hospitalization were compared between patients undergoing day cholecystectomy and night cholecystectomy. RESULTS: Complication rates and costs did not differ between the day and night groups. Length of stay was shorter in the night group (2.4 vs 2.8 days, p = 0.002). CONCLUSIONS: Performing LC for acute cholecystitis during night-time hours does not increase risk of complications and decreases length of stay.

BACKGROUND: A subset of patients explored for abdominal injury have persistent hepatic bleeding on postoperative computed tomography (CT) and/or angiography, either not identified or not manageable at initial laparotomy. To identify patients at risk for ongoing hemorrhage and guide triage to angiography, we investigated the relationship of early postoperative CT scan with outcomes in operative hepatic trauma. METHODS: This is a retrospective review of 528 patients with hepatic injury taken to laparotomy without imaging within 6 hours of arrival to six trauma centers from 2007 to 2013, coordinated through the Western Trauma Association multicenter trials group. RESULTS: A total of 528 patients were identified, with a mean age of 31 years, 82% male, and 37% blunt injury; mean (SD) Injury Severity Score (ISS) was 27 (16) and base deficit was -9 (6); in-hospital mortality was 26%. Seventy-three patients died during initial exploration. Of 455 early survivors, 123 (27%) had a postoperative contrast CT scan within 24 hours of laparotomy. CT patients had more common blunt injury, higher ISS, and lower base deficit than those who did not undergo CT. CT identified hepatic contrast extravasation or pseudoaneurysm in 10 patients (8%). Hepatic bleeding on CT was 83% sensitive and 75% specific (likelihood ratio, 3.3) for later positive angiography; negative CT finding was 96% sensitive and 83% specific (likelihood ratio, 5.7) for later negative or not performed angiography. Despite occurring in a more severely injured cohort, performance of early postoperative CT was associated with reduced mortality (odds ratio, 0.16) in multivariate analysis. Blunt mechanism was also a multivariate predictor of mortality (odds ratio, 3.0). CONCLUSION: Early postoperative CT scan after laparotomy for hepatic trauma identifies clinically relevant ongoing bleeding and is sufficiently sensitive and specific to guide triage to angiography. Contrast CT should be considered in the management algorithm for hepatic trauma, particularly in the setting of blunt injury. Further study should identify optimal patient selection criteria and CT scan timing in this population. LEVEL OF EVIDENCE: Care management/therapeutic study, level IV; epidemiologic/prognostic study, level III.
