Multiple studies have shown improved outcomes and higher utilization of care with the increase of insurance coverage. This study aims to assess whether Medicaid expansion (ME) has changed the utilization and outcomes of abdominal aortic aneurysm (AAA) repair in the United States. Retrospective observational study. Data of patients undergoing AAA repair in the Vascular Quality Initiative (2010-2017). Interrupted time-series (ITS) analysis was utilized to evaluate changes in annual trends of postoperative outcomes after elective AAA repair before and after 2014. We also assessed if these trend changes were significant by comparing the changes in states which adopted ME in 2014 versus nonexpansion states (NME), and conducting a difference-in-difference analysis. Primary outcomes included in-hospital mortality and adverse events (bowel and leg ischemia, cardiac, renal, respiratory, stroke and return to the OR). A total of 19,143 procedures were included (Endovascular: 85.8% and open: 14.2%), of which 40.9% were performed in ME States. Compared to preexpansion trends (P1), there was a 2% annual increase in elective AAA repair in ME states (P1: -1.8% versus P2: +0.2%, P < 0.01) with no significant change in NME (P1: +0.3% versus P2: +0.2%, P = 0.97). Among elective cases, annual trends in the use of EVAR increased by 2% in ME states (95% confidence interval (CI) = -0.1, 4.1, P = 0.06), compared to a 3% decrease in NME States [95%CI = -5.8, -0.6, P = 0.01) (P ME versus NME < 0.01]. There was no association between ME and in-hospital mortality. Nonetheless, it was associated with a decrease in the annual trends of in-hospital complications (ME: -1.4% (-2.1,-0.8) versus NME: +0.2% (-0.2, +0.8), P < 0.01). While no association between ME and increased survival was noted in states which adopted ME, there was a significant increase of elective AAA cases and EVAR utilization and a decrease in in-hospital complications in ME States.

In its normal anatomy, the extracranial internal carotid artery (ICA) does not have branches. The most common cause of an extracranial ICA branch is the ectopic placement of one of the named external carotid artery branches. Other causes of extracranial ICA branches include persistent fetal carotid-vertebrobasilar anastomoses and recannalized intersegmental arteries. In this case, report we describe a 55-year-old male who was found to have an ascending pharyngeal artery (APA) arising from the ICA during neck dissection. The aberrant APA was not identified on pre-operative imaging. The patient underwent a successful carotid endarterectomy (CEA) with preservation of flow through the ascending pharyngeal. We review the literature on the origin of the APA and discuss the clinical implications of extracranial ICA branches. [ABSTRACT FROM AUTHOR]

Aortoesophageal fistula (AEF) as a result of prolonged nasogastric intubation is rare and certainly fatal, without prompt surgical intervention. We report the case of a 41-year-old man with morbid obesity who was admitted after suffering 55% of total body surface area burns. After several skin graft operations over the course of 12 weeks, he was rushed into surgery because of the acute onset of severe upper gastrointestinal bleeding. Exploratory laparotomy and esophagogastroduodenoscopy (EGD) suggested an AEF, which was then quickly confirmed by a diagnostic angiogram. An endovascular aortic stent graft repair was performed that successfully stopped the bleeding. We include a review of the literature pertaining to cases of AEF treated by endovascular surgery, which appears to be a promising alternative to open surgery in the unfit patient.

Carotid artery revascularization has traditionally been performed by either a carotid endarterectomy or carotid artery stent. Large data analysis has suggested there are differences in perioperative outcomes with regards to race, with non-White patients (NWP) having worse outcomes of stroke, restenosis and return to the operating room (RTOR). The introduction of transcarotid artery revascularization (TCAR) has started to shift the paradigm of carotid disease treatment. However, to date, there have been no studies assessing the difference in postoperative outcomes after TCAR between racial groups. All patients from 2016 to 2021 in the Vascular Quality Initiative who underwent TCAR were included in our analysis. Patients were split into two groups based on race: individuals who identified as White and a second group that comprised all other races. Demographic and clinical variables were compared using Student's t-Test and chi-square test of independence. Logistic regression analysis was performed to determine the impact of race on perioperative outcomes of stroke, myocardial infarction (MI), death, restenosis, RTOR, and transient ischemic attack (TIA). The cohort consisted of 22,609 patients: 20,424 (90.3%) White patients and 2185 (9.7%) NWP. After adjusting for sex, diabetes, hypertension, coronary artery disease, history of prior stroke or TIA, symptomatic status, and high-risk criteria at time of TCAR, there was a significant difference in postoperative stroke, with 63% increased risk in NWP (odds ratio = 1.63, 95% confidence interval: 1.11-2.40, P = 0.014). However, we found no significant difference in the odds of MI, death, postoperative TIA, restenosis, or RTOR when comparing NWP to White patients. This study demonstrates that NWP have increased risk of stroke but similar outcomes of death, MI, RTOR and restenosis following TCAR. Future studies are needed to elucidate and address the underlying causes of racial disparity in carotid revascularization. [ABSTRACT FROM AUTHOR]

Prior studies have demonstrated acceptable midterm outcomes with prosthetic conduits for above-knee bypass for occlusive disease in patients with inadequate segment great saphenous vein (GSV). In this study we aimed to investigate whether this holds true for open repair of popliteal artery aneurysms (PAA). We queried the Vascular Quality Initiative data for patients who underwent open PAA repair (OPAR). We divided the cohort into three groups based on the conduit used: GSV, other autologous veins, or prosthetic graft. Study outcomes included primary patency, freedom from major amputation, amputation-free survival, and overall survival at 1 y. Kaplan–Meier survival estimates, log-rank tests and multivariable Cox regression were used to compare outcomes between study groups. A total of 4016 patients underwent bypass for PAA from January 2010 to October 2021. The three cohorts were significantly different in many demographic and clinical characteristics. The adjusted odds of postoperative amputation among symptomatic patients were 3-fold higher for prosthetic conduits compared to the GSV (odds ratio, 3.20; 95% CI, 1.72-5.92; P < 0.001). For the 1-y outcomes, the adjusted risk of major amputation was almost 3-fold higher for patients with symptomatic disease undergoing bypass with prosthetic conduits (hazard ratio [HR], 2.97; 95% CI, 1.35-6.52; P = 0.007). When compared with GSV, prosthetic conduits were associated with 96% increased risk of death when used for repair in symptomatic patients (adjusted hazard ratio (aHR), 1.96; 95% CI, 1.29-2.97; P = 0.002) but no significant association with mortality in asymptomatic patients (aHR, 0.83; 95% CI, 0.37-1.87; P = 0.652). When compared with GSV, prosthetic conduits were associated with a 2-fold increased risk of 1-y major amputation or death when used for repair in symptomatic patients (aHR, 2.03; 95% CI, 1.40-2.94; P < 0.001) but no significant association with mortality in asymptomatic patients (aHR, 0.91; 95% CI, 0.42-1.98; P = 0.816). Comparing bypass with other veins to the GSV among patients with symptomatic disease, there was no statistically significant difference in major amputation risk (HR; 2.44; 95% CI, 0.55-10.82; P = 0.242) and no difference in the adjusted risk of all-cause mortality (aHR, 0.77; 95% CI, 0.26-2.44; P = 0.653). There were no differences in the adjusted risk of loss of primary patency comparing other veins to GSV (HR, 1.53; 95% CI, 0.85-2.76; P = 0.154) and prosthetic conduits to GSV (HR, 0.85; 95% CI, 0.57-1.26; P = 0.422). This large study shows that among patients undergoing OPAR, 1-y primary patency does not differ between conduit types. However, prosthetic conduits are associated with significantly higher risk of amputation and death compared to GSV among symptomatic patients. Though non-GSV autologous veins are less often used for OPAR, they have comparably acceptable outcomes as GSV. • Type of Research : Retrospective review of prospectively collected multicenter Vascular Quality Initiative data. • Key Findings : In this study of 4016 patients who underwent bypass for popliteal artery aneurysms, 1 y primary patency did not differ among the conduit types; however, in symptomatic patients prosthetic conduits were associated with higher odds of death and major amputation compared to great saphenous vein (GSV) conduit. Small vein conduits had comparably acceptable outcomes as GSV. In asymptomatic patients, the conduit type was not associated with significant differences in outcomes of major amputation and all-cause mortality. • Take Home Message : GSV conduits should be preferred to prosthetic conduits in symptomatic patients, and if not available, other small vein conduits offer similar outcomes.

BACKGROUND: Endovascular aneurysm repair (EVAR) is often attempted in patients with marginal anatomy. These patients' midterm outcomes are available in the Vascular Quality Initiative for analysis. STUDY DESIGN: Retrospective analysis of prospectively collected data in the Vascular Quality Initiative from patients who underwent elective infrarenal EVAR between 2011 and 2018. Each EVAR was identified as either on- or off-instructions for use (IFU) based on aortic neck criteria. Multivariate logistic regression models were used to assess associations between aneurysm sac enlargement, reintervention, and type Ia endoleak with IFU status. Kaplan-Meier time-to-event models estimated reintervention, aneurysm sac enlargement, and overall survival. RESULTS: We identified 5,488 patients with at least 1 follow-up recorded. Those treated off-IFU included 1,236 patients ([23%] mean follow-up 401 days) compared with 4,252 (77%) treated on-IFU (mean follow-up 406 days). There was no evidence of significant differences in crude 30-day survival (96% vs 97%; p = 0.28) or estimated 2-year survival (97% vs 97%; log-rank p = 0.28). Crude type Ia endoleak frequency was greater in patients treated off IFU (2% vs 1%; p = 0.03). Off-IFU EVAR was associated with type Ia endoleak on multivariable regression model (odds ratio 1.84 [95% CI 1.23 to 2.76]; p = 0.003). Patients treated off IFU vs on IFU experienced had increased risk of reintervention within 2 years (7% vs 5%; log-rank p = 0.02), a finding consistent with results from the Cox modeling (hazard ratio 1.38 [95% CI 1.06 to 1.81]; p = 0.02). CONCLUSIONS: Patients treated off IFU were at greater risk for type Ia endoleak and reintervention, although they had similar 2-year survival compared with those treated on IFU. Patients with anatomy outside IFU should be considered for open surgery or complex endovascular repair to reduce the probability for revision. [ABSTRACT FROM AUTHOR]

The prevalence and costs of chronic venous ulcer care in the US are increasing. The Johns Hopkins University Evidence- Based Practice Center recently completed a systematic review of the comparative effectiveness of advanced wound dressings, antibiotics, and surgical management of chronic venous ulcers. Of 10,066 citations identified in the literature search, only 66 (0.06%) met our liberal inclusion criteria for providing evidence on the effectiveness of interventions for chronic venous ulcers. Based on review of those studies, members of our team and a panel of informed stakeholders identified important research gaps and methodological deficiencies and prioritized specific future research needs. Based on that review, we provide the results of our assessment of future research needs for chronic venous ulcer care. Advanced wound dressings were considered to have the highest priority for future research, followed by venous surgery and antibiotics. An imperative from our assessment is that future research evaluating interventions for chronic venous ulcers meet quality standards. In a time of increasing cost pressure, the wound care community needs to develop high-quality evidence to justify the use of present and future therapeutic modalities. [ABSTRACT FROM AUTHOR]

Background: Little is known about the best revascularization procedure for patients with contralateral carotid artery occlusion (CCO). We aim to compare the outcomes of transcarotid artery revascularization (TCAR), carotid endarterectomy (CEA), and transfemoral carotid artery stenting (TFCAS) in patients with CCO.Study Design: Patients in the Vascular Quality Initiative dataset who underwent CEA, TFCAS, or TCAR, and had CCO between September 2016 and April 2020, were included. Multivariable logistic analysis was used to evaluate in-hospital outcomes.Results: The final cohort included 1,144 TCARs, 1,182 TFCAS, and 2,527 CEA procedures performed in patients with CCO. Compared with TFCAS, TCAR was associated with a significant reduction in the odds of in-hospital stroke or death (odds ratio [OR] 0.26; 95% CI: 0.12-0.59; p < 0.01). However, no significant difference in stroke was noted (OR 0.71; 95% CI 0.34-1.51; p = 0.38). These results persisted after stratifying with respect to symptomatic status (p values of interaction = 0.92 and 0.74, respectively). There was no significant difference between TCAR and CEA in odds of in-hospital stroke or death on multivariable adjustment (OR 0.57; 95% CI: 0.29-1.10, p = 0.10). The interaction between procedure type and symptomatic status in predicting in-hospital stroke was statistically significant (p = 0.04). In asymptomatic patients, TCAR was associated with a 50% to 60% reduction in the odds of stroke (p = 0.04). Yet, no significant differences were observed in symptomatic patients.Conclusions: TCAR has lower odds of in-hospital stroke or death compared to TFCAS, independent of symptomatic status. Compared to CEA, TCAR seems to be a better option in asymptomatic patients, with lower odds of in-hospital stroke. Yet, no significant difference is observed in symptomatic patients.

Background: Intensive care unit (ICU) admission after endovascular aortic aneurysm repair (EVAR) varies across medical centers. We evaluated the association of postoperative ICU use with perioperative and long-term outcomes after EVAR.Study Design: The Vascular Quality Initiative (2003-2019) was queried for index elective EVARs. Included centers were categorized by percentage of patients with EVARs postoperatively admitted to the ICU; routine ICU (rICU) centers as ≥80% ICU admissions and nonroutine ICU (nrICU) centers as ≤20% ICU admissions. Patients admitted preoperatively or with same day discharge were excluded. Perioperative outcomes and survival were compared between rICU and nrICU centers.Results: Of 45,310 EVARs in the database, 35,617 were performed at rICU or nrICU centers - 5,443 (15.3%) at 71 rICU centers and 30,174 (84.7%) at 200 nrICU centers. Overall, mean age was 73.4 years and 81.6% were male. Postoperative myocardial infarction, pulmonary complications, stroke, leg ischemia, and in-hospital mortality were similar between rICU and nrICU centers (all p > 0.05). Postoperative length of stay (LOS) was prolonged at rICU centers (mean) (2.2 ± 3.6 vs 2 ± 4.2 days, p < 0.001). One-year survival was similar between rICU and nrICU centers, respectively, (94.9% vs 95.4%, p = 0.085). When compared with nrICU centers, rICU centers had similar 1-year mortality risk (hazard ratio [HR] 1.15, 95% CI 0.99-1.34, p = 0.076), but were associated with longer postoperative LOS (means ratio 1.1, 95% CI 1.08-1.13, p < 0.001).Conclusions: Routine ICU use after EVAR was associated with prolonged postoperative LOS, without improved perioperative/long-term morbidity or mortality. Updated care pathways to include postoperative admission to lower acuity care units may reduce costs without compromising care. [ABSTRACT FROM AUTHOR]

Objectives: We sought to develop a prediction score with data from the Vascular Quality Initiative (VQI) EVAR in efforts to assist endovascular specialists in deciding whether or not a patient is appropriate for short-stay discharge. Background: Small series describe short-stay discharge following elective EVAR. Our study aims to quantify characteristics associated with this decision. Methods: The VQI EVAR and NSQIP datasets were queried. Patients who underwent elective EVAR recorded in VQI, between 1/2010-5/2017 were split 2:1 into test and analytic cohorts via random number assignment. Cross-reference with the Medicare claims database confirmed all-cause mortality data. Bootstrap sampling was employed in model. Deep learning algorithms independently evaluated each dataset as a sensitivity test. Results: Univariate outcomes, including 30-day survival, were statistically worse in the DD group when compared to the SD group (all P < 0.05). A prediction score, SD-EVAR, derived from the VQI EVAR dataset including pre- and intra-op variables that discriminate between SD and DD was externally validated in NSQIP (Pearson correlation coefficient = 0.79, P < 0.001); deep learning analysis concurred. This score suggests 66% of EVAR patients may be appropriate for short-stay discharge. A free smart phone app calculating short-stay discharge potential is available through QxMD Calculate https://qxcalc.app.link/vqidis. Conclusions: Selecting patients for short-stay discharge after EVAR is possible without increasing harm. The majority of infrarenal AAA patients treated with EVAR in the United States fit a risk profile consistent with short-stay discharge, representing a significant cost-savings potential to the healthcare system.

The impact of race and gender on surgical outcomes has been studied in infrainguinal revascularization for peripheral arterial disease. The aim of this study is to explore how race and gender affect the outcomes of suprainguinal bypass (SIB) for aortoiliac occlusive disease. Patients who underwent SIB were identified from the procedure-targeted National Surgical Quality Improvement Program data set (2011-2016). Patients were stratified into four groups: nonblack males, black males (BM), nonblack females, and black females (BF). Primary outcomes were 30-d major adverse cardiac events, a composite of myocardial infarction, stroke, or death; postoperative bleeding requiring transfusion or intervention; major amputation and prolonged length of stay (>10 d). Predictors of outcomes were determined by multivariable logistic regression analysis. About 5044 patients were identified. BM were younger, more likely to be smokers, less likely to be on antiplatelet drug or statin, and to receive elective SIB (all P ≤ 0.01). BFs were more likely to be diabetic and functionally dependent (all P ≤ 0.02). Major adverse cardiac events were not significantly different among all groups. BM had a threefold higher risk of amputation (adjusted odds ratio [OR] [95% confidence interval (95% CI)], 3.10 [1.50-6.43]; P < 0.002). Female gender was associated with bleeding in both races, that association was more drastic in BF (OR [95% CI], 2.43 [1.63-3.60]; P < 0.0001), whereas nonblack females (OR [95% CI], 1.46 [1.19-1.80]; P < 0.0001). BF had higher odds of prolonged length of stay (OR [95% CI]: 1.62 [1.08-2.42]; P < 0.019). In this large retrospective study, we demonstrated the racial and gender disparity in SIB outcomes. BM had more than threefold increase in amputation risk as compared with nonblack males. Severe bleeding risk was more than doubled in BF. Race and gender consideration is warranted in risk assessment when patients are selected for aortoiliac disease revascularization, which in turn necessitate preoperative risk modification and optimization in addition to enhancing their access to primary preventive care measures.

Background: Transcarotid artery revascularization (TCAR) with flow reversal was recently introduced as a novel technique for carotid artery stenting (CAS). We examined the learning curve of surgeons adopting TCAR based on data from the Vascular Quality Initiative (VQI-TCAR Surveillance Project; TSP).Study Design: We identified all patients in the TSP who underwent TCAR from September 2016 to December 2018. Cases were numbered in chronological order for each unique surgeon. Patients were then divided into 4 levels based on surgeon case number for comparison: cases 1 to 5 (novice), cases 6 to 20 (intermediate), cases 20 to 30 (advanced), and cases >30 (expert).Results: During the study period, 3,456 TCAR procedures were performed by 417 unique surgeons from 178 centers. Of all procedures, 1,426 (41%) were performed at the novice level, 1,375 (40%) at the intermediate level, 307 (8.9%) at the advanced level, and 348 (10%) at the expert level. Cases performed at more advanced levels had lower operative times (novice 82 vs intermediate 73 vs advanced 62 vs expert 60 minutes, p < 0.001), fluoroscopy time (7 vs 6 vs 5 vs 5 minutes, p < 0.001), and flow reversal time (12 vs 11 vs 10 vs 10 minutes, p < 0.001). Cases done at more advanced levels had decreases in bleeding (3.9% vs 3.4% vs 1.6% vs 1.2%, p = 0.03). No differences in major in-hospital outcomes were found regardless of experience level including stroke (p = 0.99), death (p = 0.39), and composite stroke/death/myocardial infarction (p = 0.84).Conclusions: Transcarotid artery revascularization is being performed with excellent stroke and mortality rates in the TSP, even in the early stages of the surgeons' learning curve. Bleeding complications, operative, fluoroscopy, and flow reversal times all decrease with increasing TCAR experience. [ABSTRACT FROM AUTHOR]

Importance: Several trials have observed higher rates of perioperative stroke following transfemoral carotid artery stenting compared with carotid endarterectomy. Transcarotid artery revascularization with flow reversal was recently introduced for carotid stenting. This technique was developed to decrease stroke risk seen with the transfemoral approach; however, its outcomes, compared with transfemoral carotid artery stenting, are not well characterized.Objective: To compare outcomes associated with transcarotid artery revascularization and transfemoral carotid artery stenting.Design, Setting, and Participants: Exploratory propensity score-matched analysis of prospectively collected data from the Vascular Quality Initiative Transcarotid Artery Surveillance Project and Carotid Stent Registry of asymptomatic and symptomatic patients in the United States and Canada undergoing transcarotid artery revascularization and transfemoral carotid artery stenting for carotid artery stenosis, from September 2016 to April 2019. The final date for follow-up was May 29, 2019.Exposures: Transcarotid artery revascularization vs transfemoral carotid artery stenting.Main Outcomes and Measures: Outcomes included a composite end point of in-hospital stroke or death, stroke, death, myocardial infarction, as well as ipsilateral stroke or death at 1 year. In-hospital stroke was defined as ipsilateral or contralateral, cortical or vertebrobasilar, and ischemic or hemorrhagic stroke. Death was all-cause mortality.Results: During the study period, 5251 patients underwent transcarotid artery revascularization and 6640 patients underwent transfemoral carotid artery stenting. After matching, 3286 pairs of patients who underwent transcarotid artery revascularization or transfemoral carotid artery stenting were identified (transcarotid approach: mean [SD] age, 71.7 [9.8] years; 35.7% women; transfemoral approach: mean [SD] age, 71.6 [9.3] years; 35.1% women). Transcarotid artery revascularization was associated with a lower risk of in-hospital stroke or death (1.6% vs 3.1%; absolute difference, -1.52% [95% CI, -2.29% to -0.75%]; relative risk [RR], 0.51 [95% CI, 0.37 to 0.72]; P < .001), stroke (1.3% vs 2.4%; absolute difference, -1.10% [95% CI, -1.79% to -0.41%]; RR, 0.54 [95% CI, 0.38 to 0.79]; P = .001), and death (0.4% vs 1.0%; absolute difference, -0.55% [95% CI, -0.98% to -0.11%]; RR, 0.44 [95% CI, 0.23 to 0.82]; P = .008). There was no statistically significant difference in the risk of perioperative myocardial infarction between the 2 cohorts (0.2% for transcarotid vs 0.3% for the transfemoral approach; absolute difference, -0.09% [95% CI, -0.37% to 0.19%]; RR, 0.70 [95% CI, 0.27 to 1.84]; P = .47). At 1 year using Kaplan-Meier life-table estimation, the transcarotid approach was associated with a lower risk of ipsilateral stroke or death (5.1% vs 9.6%; hazard ratio, 0.52 [95% CI, 0.41 to 0.66]; P < .001). Transcarotid artery revascularization was associated with higher risk of access site complication resulting in interventional treatment (1.3% vs 0.8%; absolute difference, 0.52% [95% CI, -0.01% to 1.04%]; RR, 1.63 [95% CI, 1.02 to 2.61]; P = .04), whereas transfemoral carotid artery stenting was associated with more radiation (median fluoroscopy time, 5 minutes [interquartile range {IQR}, 3 to 7] vs 16 minutes [IQR, 11 to 23]; P < .001) and more contrast (median contrast used, 30 mL [IQR, 20 to 45] vs 80 mL [IQR, 55 to 122]; P < .001).Conclusions and Relevance: Among patients undergoing treatment for carotid stenosis, transcarotid artery revascularization, compared with transfemoral carotid artery stenting, was significantly associated with a lower risk of stroke or death.

Objective: The purpose of this study is to use a large, nationally representative vascular database to assess differences in patient characteristics, aortic neck anatomy, and outcomes between men and women following open (open aneurysm repair [OAR]) and endovascular (endovascular aneurysm repair [EVAR]) abdominal aortic aneurysm (AAA) repair. Methods: Patients undergoing AAA repair from 2003 to 2018 in Vascular Quality Initiative were identified and stratified by procedure (EVAR vs OAR). Thirty-day mortality and major in-hospital complications were assessed between genders within each operative cohort. An EVAR subset analysis was performed to assess differences in aortic neck anatomy; hostile neck anatomy was defined as length <15 mm (L < 15), angle >60° (A > 60), and/or diameter >28 mm (D > 28). Standard univariate and multivariable analyses were performed. Results: A total of 50 213 patients were identified: 9263 (19%) OAR and 40 950 (82%) EVAR. In both cohorts, majority of patients were men (OAR 73% and EVAR 81%). Women were more likely to have a hostile neck (31.7% vs 24.1%, P <.001), L < 15 (19.8% vs 11.9%, P <.001), and A > 60 (11.5% vs 5.4%, P <.001). Men had larger aneurysm (mean, 57 vs 55 mm, P <.001) and were more likely to have D > 28 (14.0% vs 10.6%, P <.001). Women undergoing EVAR were more likely to undergo aortic extensions (21.9% vs 16.0%) and receive higher contrast volume. After adjusting for potential confounders, female gender was associated with 86% and 50% increased risk of 30-day mortality in OAR and EVAR, respectively. Women were more likely than men to experience renal, cardiac, and pulmonary complications only in the EVAR cohort. Women had a 2-fold increased odds of developing type 1 endoleak. Conclusion: Our study demonstrates unfavorable neck anatomy occurs more frequently in women compared to men. Women were also at an increased risk of developing major complications, particularly following EVAR. Careful patient selection is indicated in all patients to reduce complications, with special attention in women with hostile neck. [ABSTRACT FROM AUTHOR]

Objectives: Carotid artery endarterectomy (CEA) and carotid artery stenting (CAS) are 2 effective treatment options for carotid revascularization and stroke prevention. The long-term outcomes of Carotid Revascularization Endarterectomy versus Stenting Trial (CREST) reported similar stroke and death rate between the 2 procedures. This study presents the short- and long-term outcomes of CEA and CAS of all risk patients performed by a single vascular surgeon in a real-world setting. Methods: We retrospectively reviewed all patients who underwent CEA and CAS from September 2005 to June 2017 at our institute. Student t test, χ2, and Fisher exact tests were used to compare patient's characteristics. Multivariate logistic, cox regression models and survival analysis were used to compare postoperative and long-term outcomes between the 2 groups. Results: Over 2000 patients were evaluated for carotid artery stenosis during the study period, and 313 revascularization procedures were performed (CEA: 47%, CAS: 53%). Patients' age (Mean [95% confidence interval, CI] 68.8 [67.2-70.4] vs 69.7 [68.2-71.3], P = .40) was similar between CEA and CAS. Patients who underwent CAS had significantly higher comorbidities (chronic obstructive pulmonary disease [COPD], chronic heart failure [CHF], hyperlipidemia, and prior ipsilateral intervention, all P < .05). No difference was found in 30-day complications after CEA versus CAS including stroke (2.0% vs 1.2%), myocardial infarction (MI; 0.7% vs 1.2%), death (0% vs 1.2%) as well as combined major adverse events (stroke/death/MI; 2.7% vs 3.0%; all P > .05). Overall 7-year survival, stroke-free survival and restenosis-free survival were similar between the 2 groups (P > .5). Significant predictors of mortality were diabetes (hazard ratio, HR [95% CI]: 2.41 [1.15-5.08]), chronic kidney disease (HR [95% CI]: 4.89 [1.97-12.13]), and COPD (HR [95% CI]: 3.31 [1.43-7.71]; all P values <.05). Statin use was protective with 71% reduction in risk of mortality (HR [95% CI]: 0.29 [0.12-0.67], P = .004). Conclusion: Our experience showed comparable short- and long-term outcomes of CAS and CEA performed for carotid artery stenosis by vascular surgeon. There was no difference between single institutional long-term outcomes and CREST outcomes following CEA and CAS. [ABSTRACT FROM AUTHOR]

Background: Fenestrated endovascular repair (FEVAR) and chimney endovascular repair (ChEVAR) endovascular repair offer a less invasive alternative to open aortic repair (OAR) in managing juxtarenal, pararenal, and suprarenal abdominal aortic aneurysms (AAAs). The aim of this study is to evaluate the 30-day postoperative outcomes following endovascular and open repair of nonruptured AAA involving the renal vessels. Study Design: All patients undergoing endovascular (FEVAR and ChEVAR) and open repair of juxtarenal, pararenal, and suprarenal AAA in National Surgical Quality Improvement Program database from 2012 to 2016 were included. Continuous and categorical covariates were analyzed using medians and χ2/Fisher exact test, respectively. Multivariable logistic regression analyses were performed to evaluate primary (mortality) and secondary (renal and cardiopulmonary failure) outcomes between open versus endovascular approach. Results: A total of 1191 patients underwent AAA repair using open (72%) or endovascular (FEVAR: 14%, ChEVAR: 14%) approach. In univariate analysis, no significant difference in 30-day mortality was seen between the 3 groups (FEVAR: 2.47% vs ChEVAR: 7.32% vs OAR: 6.13%, P = .13). However, 30-day major complications including renal failure (9.36% vs 6.10% vs 1.85%, P = .003) and cardiopulmonary complications (19.77% vs 3.66% vs 4.94%, P < 001) failure were significantly higher in patients undergoing OAR versus ChEVAR versus FEVAR. After adjusting for potential confounders, OAR was associated with 2- to 5-folds increased risk of mortality (odds ratio, OR [95% confidence interval, CI]: 2.14 [1.09-4.21], P = .03), renal (OR [95% CI]: 2.87 [1.48-5.57], P = .002), and cardiopulmonary failure (OR [95% CI]: 4.63 [2.47-8.67], P < .001) compared to any endovascular repair. Conclusion: Using a large national surgical data set, our study found 2- to 5-folds higher mortality and morbidity in patients undergoing open versus endovascular repair of AAA involving the renal vessels. Endovascular repair seems to be a safer approach, especially when managing older patients with AAA. [ABSTRACT FROM AUTHOR]

Background Hemodialysis (HD) has been shown to be an independent predictor of poor outcomes after femoropopliteal revascularization procedures in patients with chronic limb-threatening ischemia. However, HD patients tend to have isolated infrageniculate disease, an anatomic risk factor for inferior patency. We aimed to compare outcomes for HD versus non-HD patients after infrageniculate open lower extremity bypass (LEB) and endovascular peripheral vascular interventions (PVIs). Methods Data from the Society for Vascular Surgery Vascular Quality Initiative database (2008-2014) were analyzed. All patients undergoing infrageniculate LEB or PVI for rest pain or tissue loss were included. One-year primary patency (PP), secondary patency (SP), and major amputation outcomes were analyzed for HD versus non-HD patients stratified by treatment approach using both univariable and multivariable analyses. Results A total of 1688 patients were included, including 348 patients undergoing LEB (HD = 44 versus non-HD = 304) and 1340 patients undergoing PVI (HD = 223 versus non-HD = 1117). Patients on HD more frequently underwent revascularization for tissue loss (89% versus 77%, P < 0.001) and had ≥2 comorbidities (91% versus 76%, P < 0.001). Among patients undergoing LEB, 1-y PP (66% versus 69%) and SP (71% versus 78%) were similar for HD versus non-HD ( P ≥ 0.25) groups, but major amputations occurred more frequently in the HD group (27% versus 14%; P = 0.03). Among patients undergoing PVI, 1-y PP (70% versus 78%) and SP (82% versus 90%) were lower and the frequency of major amputations was higher (27% versus 10%) for HD patients (all, P ≤ 0.02). After correcting for baseline differences between the groups, outcomes were similar for HD versus non-HD patients undergoing LEB ( P ≥ 0.21) but persistently worse for HD patients undergoing PVI (all, P ≤ 0.006). Conclusions HD is an independent predictor of poor patency and higher risk of major amputation after infrageniculate endovascular revascularization procedures for the treatment of chronic limb-threatening ischemia. The use of endovascular interventions in these higher risk patients is not associated with improved limb salvage outcomes and may be an inappropriate use of healthcare resources.

Background We aim to describe trends in failure to rescue (FTR) among elderly patients undergoing elective open aortic aneurysm repair (OAR) and endovascular aortic aneurysm repair (EVAR). Materials and methods All patients aged ≥80 y recorded in the Vascular Quality Initiative database (2002-2014) undergoing nonruptured infrarenal AAA repair were included. Primary outcome was FTR, defined as percentage of deaths in patients who had a complication within 30 d of surgery. Univariable and multivariable statistics were used to identify risk factors for FTR following OAR and EVAR procedures. Results 975 elderly patients underwent AAA repair during the study period (EVAR = 667, OAR = 308). Overall FTR was 10%, most commonly related to acute kidney injury (62%) and respiratory failure (53%). Independent predictors of FTR included female gender (odds ratio [OR] 1.95), multiple comorbidities (OR 1.98), renal insufficiency (OR 1.97), peripheral vascular disease (OR 2.42), and perioperative vasopressor use (OR 4.49) (all, P < 0.02). Obesity was protective (OR 0.58, P = 0.02). FTR was higher following OAR versus EVAR (14% versus 9%; P = 0.02) on univariable analysis, but there was no significant difference between operative approaches after risk adjustment (OR 1.15, P = 0.60). Comparing elderly versus younger patients ( n = 2854), FTR was significantly higher for the elderly for both OAR (OR 2.0, 95% CI 1.36-3.01) and EVAR (OR 1.60, 95% CI 1.07-2.40). Conclusions FTR after AAA repair is not uncommon among elderly patients and could explain the higher mortality observed in this group compared to the general population. Overall health status should be carefully considered when weighing the risks versus benefits of performing AAA repair in patients aged ≥80 y. [ABSTRACT FROM AUTHOR]

We evaluated the occurrence of thoracic outlet syndrome (TOS) and 30-day postoperative outcomes. Patients undergoing cervical/first rib resection surgery were identified in the American College of Surgeons National Surgical Quality Improvement Program database (2005-2013). Thoracic outlet syndrome types were then examined. Propensity score matching was performed to account for potential confounders; 1180 patients were explored during the study period, 1007 (85.3%) were of the neurogenic TOS (NTOS), 32 (2.7%) patients had arterial TOS (ATOS), and 141 (12.0%) patients had venous TOS (VTOS). Patients with ATOS were significantly older (median age [interquartile range, IQR]--NTOS: 34 [25-44], ATOS: 49.5 [42.5-57], VTOS: 34 [23-43]; P < .001). Median operating time was significantly longer for patients with ATOS. Median in-hospital stay was also longer for patients with ATOS (median length of in-hospital stay [LOS; IQR]--NTOS: 2 [1-4]; ATOS: 6 [3-7]; and VTOS: 5 [2-7] days; P < .001). Patients with VTOS showed twice longer LOS when compared to NTOS after matching. Presentation and treatment of TOS have been studied extensively at highly experienced centers. [ABSTRACT FROM AUTHOR]

Background Age is a well-known risk factor for postoperative death in patients with abdominal aortic aneurysms (AAA), and the efficacy of open aneurysm repair (OAR) and endovascular aneurysm repair (EVAR) remains controversial in the elderly population. The aim of this study was to determine the predictors of 30-d mortality after AAA repair in elderly population. Methods Using the National Surgical Quality Improvement Program vascular-targeted database (2011-2014), we identified all patients aged >70 y who underwent OAR and EVAR for nonruptured AAA. Univariate and multivariable logistic regression analyses were implemented to examine postoperative mortality adjusting for patient demographics and characteristics. Results A total of 4229 nonruptured AAA repairs were performed (OAR: 360 [8.5%] versus EVAR: 3869 [91.5%]). Most patients were males (79 %) and White (81%) with a mean age of 78 ± 6 y. Obesity was more prevalent in EVAR group (31% versus 24%, P = 0.008). Whereas, smoking was more likely to be seen in patients undergoing an OAR (35% versus 22%, P < 0.001). The 30-d mortality was significantly higher after OAR versus EVAR (8% versus 2%, P < 0.001). After adjusting, OAR was associated with almost five times higher mortality than EVAR (adjusted odds ratio: 4.88; 2.85-8.34, P < 0.001). Conclusions This study reflects contemporary real world outcomes of nonruptured AAA repair in the elderly. Open repair was associated with almost fivefold increase in mortality compared with endovascular repair. Elderly patients who are functionally dependent are less likely to benefit from AAA repair, whether OAR or EVAR. Further prospective studies are required to better understand the predictors of mortality after AAA repair in the geriatric population which could guide decision-making and improve outcomes in this population.

Both open surgery and endovascular peripheral interventions have been shown to effectively improve outcomes in patients with peripheral artery disease, but minimal data exist comparing outcomes performed at and below the knee. The purpose of this study was to compare outcomes following infrageniculate lower extremity open bypass (LEB) versus peripheral vascular intervention (PVI) in patients with critical limb ischemia. Using data from the 2008–2014 Vascular Quality Initiative, 1-year primary patency, major amputation, and mortality were compared among all patients undergoing LEB versus PVI at or below the knee for rest pain or tissue loss. Overall, 2566 patients were included (LEB=500, PVI=2066). One-year primary patency was significantly worse following LEB (73% vs 81%; p<0.001). One-year major amputation (14% vs 12%; p=0.18) and mortality (4% vs 6%; p=0.15) were similar regardless of revascularization approach. Multivariable analysis adjusting for baseline differences between groups confirmed inferior primary patency following LEB versus PVI (HR 0.74; 95% CI, 0.60–0.90; p=0.004), but no significant differences in 1-year major amputation (HR 1.06; 95% CI, 0.80–1.40; p=0.67) or mortality (HR 0.71; 95% CI, 0.44–1.14; p=0.16). Based on these data, we conclude that endovascular revascularization is a viable treatment approach for critical limb ischemia resulting from infrageniculate arterial occlusive disease.

A type B dissection involves the aorta distal to the subclavian artery, and accounts for 25–40% of aortic dissections. Approximately 75% of these are uncomplicated with no malperfusion or ischemia. Multiple consensus statements recommend thoracic endovascular aortic repair (TEVAR) as the treatment of choice for acute complicated type B aortic dissections, while uncomplicated type B dissections are traditionally treated with medical management alone, including strict blood pressure control, as open repairs have a prohibitively high morbidity of up to 31%. However, with medical treatment alone, the morbidity, including aneurysm degeneration of the affected segment, is 30%, and mortality is 10% over 5 years. For both chronic and acute uncomplicated type B aortic dissections, emerging evidence supports the use of both best medical therapy and TEVAR. This paper reviews the current diagnosis and treatment of uncomplicated type B aortic dissections. [ABSTRACT FROM AUTHOR]

Background Open repair of thoracoabdominal and descending thoracic aneurysm (TAA) carries significant operative morbidity and mortality. Despite evolving operative techniques patient-level risk factors affecting mortality after open TAA repair, including patient functional status, remain to be fully understood. Materials and methods We identified all open TAA repair cases in the National Surgical Quality Improvement Program database between 2005 and 2013. Multivariable logistic regression was used to evaluate the effect of patients' age, gender, race, body mass index (BMI), comorbid conditions, functional status, ASA class, smoking, rupture, descending thoracic aneurysm versus Crawford types, dissection, and preoperative: transfusion, creatinine levels, on perioperative (30-d) mortality after open TAA repair. Results A total of 1048 patients underwent open TAA repair during the 9-y study period. Mean patient age was (mean ± SEM) 67 ± 0.4 y, mean BMI was 27 ± 6 kg m 2 , and most patients (60%) were male. Perioperative mortality was 14.0% (nonruptured 11.4% versus ruptured 34.2%, P < 0.01) and patients with postoperative renal failure requiring dialysis comprised 12.6%. On multivariable analysis, dependent status had the highest effect on operative mortality, tripling the risk of death (odds ratio [OR] = 3.18, 95% confidence interval [CI] = 1.49-6.81, P < 0.01). Ruptured aneurysms had more than double the operative mortality risk (OR = 2.49, 95% CI = 1.42-4.38, P < 0.01). Preoperative renal insufficiency added 23% mortality risk per unit increase in creatinine (OR = 1.23, 95% CI = 1.01-1.50, P = 0.04), whereas each year in patient age or unit increase in BMI increased the risk of death by 4% (OR = 1.04, 95% CI = 1.02-1.07, P < 0.01, OR = 1.04, 95% CI = 1.00-1.07, P = 0.04, respectively). Conclusions Patients' functional status is the strongest independent predictor of perioperative death. Other patient-level factors, including increasing age, BMI, and renal dysfunction, also play a role. Appropriate patient selection for open TAA repair is essential for achieving good outcomes.

Background The aim of our study was to compare and identify possible predictors of perioperative outcomes of carotid endarterectomy (CEA) with carotid artery stenting (CAS) using the procedure-targeted American College of Surgeons National Surgical Quality Improvement Program database. Methods Patients who underwent CEA or CAS were identified in American College of Surgeons National Surgical Quality Improvement Program (2011-2013). Univariate and multivariable logistic regression analyses were performed to evaluate the predictors of perioperative outcomes (any stroke or death, myocardial infarction [MI], 30-d readmission and reoperation). Final models were constructed based on the lowest Akaike Information Criterion. Results A total of 10,169 patients underwent carotid revascularization (CEA: 9817 [96.5%] versus CAS: 352 [3.5%]). Most patients were male (61%). Patients who had CAS were younger (mean age [±standard deviation]: 69.1 [±9.7] versus 71.3 [±9.4] y, P < 0.001); however, they showed a greater prevalence of diabetes (38.4% versus 29.2%), congestive heart failure (4.8% versus 1.4%), and chronic obstructive pulmonary disease (17.3% versus 10.2%) (all P < 0.001). The risk of postoperative stroke and/or death was nearly doubled with CAS (adjusted Odds Ratio = 1.84; 95% confidence interval: 1.07-3.18, P = 0.028). The odds of reoperation were higher in nonwhite patients compared with white patients (adjusted Odds Ratio: 1.34, 95% confidence interval: 0.97-1.84, P = 0.078). Perioperative MI and readmission were mostly related to patient's age and comorbidities. Conclusions In a national data set representing real-world outcome, CAS is associated with higher odds of postoperative mortality and stroke in comparison to CEA. Carotid revascularization procedure type is not a predictor of postoperative MI or readmission, suggesting that these outcomes are a function of other patient factors. Nonwhite race is a predictor of reoperation. [ABSTRACT FROM AUTHOR]

Background Lower extremity bypass (LEB) for peripheral vascular disease is a common procedure in diabetics and is associated with readmission. Thus, we hypothesized that diabetes might be a predictor of 30-d unplanned readmission after LEB. Methods Patients undergoing infrainguinal LEB in the 2011–12 American College of Surgeons National Surgery Quality Improvement Program database were divided into nondiabetics mellitus (NDM), non–insulin-dependent diabetics mellitus (NIDDM), and insulin-dependent diabetic mellitus (IDDM). Univariate and multivariate analyses were used to evaluate the influence of diabetes on 30-d readmission. Results A total of 9207 patients (5155 [56%] NDM, 1690 (18%) NIDDM, and 2362 (26%) IDDM) underwent LEB. Unplanned readmission was observed in 1448 patients (16%). IDDM had significantly higher crude postoperative complication (43% versus 30% NDM, 36% NIDDM; P < 0.001) and unplanned readmission rates (20% versus 14% NDM, 16% NIDDM; P < 0.001). Concomitant cardiac disease significantly modified the association between diabetes and unplanned readmission. On multivariable analysis, IDDM was an independent predictor of unplanned readmission in the absence of cardiac disease (odds ratio [OR] = 1.23; 95% confidence interval [CI], 1.03–1.47; P = 0.01). However, this association did not remain significant in the presence of cardiac disease (OR = 0.70; 95% CI, 0.48–1.01; P = 0.56). On subgroup analysis of those without cardiac disease, cardiac complications were a significant risk factor for readmission in IDDM (OR = 2.00; 95% CI, 1.12–3.57; P = 0.02) but not NDM ( P = 0.31) or NIDDM ( P = 0.10). Conclusions Although post-LEB unplanned readmission was more common among diabetics, IDDM was independently associated with unplanned readmission only in those without cardiac disease. This was driven, in part, by increased cardiac complications. Therefore, a more stringent preoperative cardiac workup in this group should be considered before LEB. [ABSTRACT FROM AUTHOR]

The purpose of this study was to systematically review the literature on the benefits and harms of advanced wound dressings on wound healing, mortality, quality of life, pain, condition of the wound bed, and adverse events for patients with chronic venous leg ulcers as compared with treatment with compression alone. We searched for primary studies in the databases of MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, and the Cumulative Index to Nursing and Allied Health Literature® from January 1980 through July 2012. Each study title, abstract, and full article was evaluated by two independent reviewers. Thirty-seven studies met our specific search criteria, although most evidence was of low or insufficient quality. Cellular dressings, collagen, and some antimicrobial dressings may improve healing rates of chronic venous leg ulcers vs. compression alone or other dressings. Limited data were available on other outcomes. The poor quality of the literature limits conclusions and necessitates future, well-conducted studies to evaluate the effectiveness of advanced wound dressings on chronic venous ulcers.

Objective: We have previously demonstrated an adverse impact of black race and Hispanic ethnicity on the outcomes of carotid endarterectomy (CEA) and carotid artery stenting (CAS). The current study was undertaken to examine the influence of race and ethnicity on the cost of CEA and CAS. Methods: The Nationwide Inpatient Sample (2005–2009) was queried using ICD-9 codes for CEA and CAS in patients with carotid artery stenosis. The primary outcome was total hospital charges. Multivariate analysis was performed using a generalized linear model adjusting for age, sex, race, comorbidities (Charlson index), high-risk status, procedure type, symptomatic status, year, insurance type, and surgeon and hospital operative volumes and characteristics. Results: Hispanic and black patients were more likely to have a symptomatic presentation, and were more likely to undergo either CEA or CAS by low-volume surgeons at low-volume hospitals (P < 0.05, all). They were also less likely to have private insurance or Medicare (P < 0.001). Overall, CEA was less expensive than CAS over the 4-y study period ($29,502 ± $104 versus $46,713 ± $409, P < 0.001). Total hospital charges after CEA were increased in both blacks ($39,562 ± $843) and Hispanics ($45,325 ± $735) compared with whites on univariate analysis ($28,403 ± $101, P < 0.001). After CAS, total hospital charges were similarly increased in both blacks ($51,770 ± $2085) and Hispanics ($63,637 ± $2766) compared with whites on univariate analysis ($45,550 ± $412, P < 0.001). On multivariable analysis, however, only Hispanic ethnicity remained independently associated with increased charges after both CEA (exponentiated coefficient 1.18; 95% CI [1.15–1.20]; P < 0.001) and CAS (exponentiated coefficient 1.17; 95% CI [1.09–1.24]; P < 0.001). Conclusion: Hispanic ethnicity was independently associated with increased hospital charges after both CEA and CAS. The increased charges seen in black patients were explained, in part, by decreased surgeon operative volume and increased postoperative complications. Further efforts are warranted to contain costs in minorities undergoing carotid revascularization. [ABSTRACT FROM AUTHOR]

Background: In the Carotid Revascularization Endarterectomy versus Stenting Trial (CREST), the composite primary endpoint of stroke, myocardial infarction, or death during the periprocedural period or ipsilateral stroke thereafter did not differ between carotid artery stenting and carotid endarterectomy for symptomatic or asymptomatic carotid stenosis. A secondary aim of this randomised trial was to compare the composite endpoint of restenosis or occlusion.Methods: Patients with stenosis of the carotid artery who were asymptomatic or had had a transient ischaemic attack, amaurosis fugax, or a minor stroke were eligible for CREST and were enrolled at 117 clinical centres in the USA and Canada between Dec 21, 2000, and July 18, 2008. In this secondary analysis, the main endpoint was a composite of restenosis or occlusion at 2 years. Restenosis and occlusion were assessed by duplex ultrasonography at 1, 6, 12, 24, and 48 months and were defined as a reduction in diameter of the target artery of at least 70%, diagnosed by a peak systolic velocity of at least 3·0 m/s. Studies were done in CREST-certified laboratories and interpreted at the Ultrasound Core Laboratory (University of Washington). The frequency of restenosis was calculated by Kaplan-Meier survival estimates and was compared during a 2-year follow-up period. We used proportional hazards models to assess the association between baseline characteristics and risk of restenosis. Analyses were per protocol. CREST is registered with ClinicalTrials.gov, number NCT00004732.Findings: 2191 patients received their assigned treatment within 30 days of randomisation and had eligible ultrasonography (1086 who had carotid artery stenting, 1105 who had carotid endarterectomy). In 2 years, 58 patients who underwent carotid artery stenting (Kaplan-Meier rate 6·0%) and 62 who had carotid endarterectomy (6·3%) had restenosis or occlusion (hazard ratio [HR] 0·90, 95% CI 0·63-1·29; p=0·58). Female sex (1·79, 1·25-2·56), diabetes (2·31, 1·61-3·31), and dyslipidaemia (2·07, 1·01-4·26) were independent predictors of restenosis or occlusion after the two procedures. Smoking predicted an increased rate of restenosis after carotid endarterectomy (2·26, 1·34-3·77) but not after carotid artery stenting (0·77, 0·41-1·42).Interpretation: Restenosis and occlusion were infrequent and rates were similar up to 2 years after carotid endarterectomy and carotid artery stenting. Subsets of patients could benefit from early and frequent monitoring after revascularisation.Funding: National Institute of Neurological Disorders and Stroke and Abbott Vascular Solutions.

Hybrid surgical and endovascular approaches such as open visceral vessel debranching and subsequent endovascular exclusion of thoracic abdominal aortic aneurysms (TAAA) represents a significant development in treatment of TAAAs. As compared to traditional endovascular aneurysm repair, hybrid repairs commonly have a higher rate of endoleak and other endograft-related complications. In this report, we present a 71 year-old man with significant comorbidities including chronic obstructive pulmonary disease, hypertension and prostate cancer. The patient after undergoing debranching of the thoracic arch followed by endograft repair of an arch aneurysm developed a proximal type I and type II endoleak fed by the previously ligated left subclavian artery. Despite coiling of the left subclavian artery and proximal extension of the endograft, a type I endoleak persisted. Severalmonths after the left subclavian arterywas coiled, a catheter was advanced through the coils and beyond the site of ligation directly into the aneurysmal sac. Once in the aneurysmal sac, multiple coils were deployed resulting in successful treatment of the type I endoleak. This report highlights the unique challenges in treating proximal descending thoracic aneurysms and represents the first report of the treatment of a type I endoleak with reaccess through a previously coiled vessel for deployment of embolics directly into the aneurysmal sac.
