RESUMEN
Endovascular stents are predominantly utilized for intra-arterial interventions; however, their application in managing venous injuries, especially traumatic ones, lacks comprehensive guidelines and long-term outcome studies. This case report discusses the innovative deployment of an infrarenal inferior vena cava stent for a traumatic inferior vena cava injury after a gunshot wound in a polytrauma patient. This case aims to enhance the existing evidence on the feasibility and potential outcomes of endovascular stenting in traumatic venous injuries.

BACKGROUND: Incisional complications of groin after inflow or infrainguinal bypasses with prosthetic conduits can result in major morbidities that require reoperation, infected graft removal, and limb loss. Muscle flaps are typically performed to treat groin wound complications, but they are also done prophylactically at the time of index procedures in certain high-risk-for-poor-healing patients to mitigate anticipated groin wound complications. We used a nationwide multi-institutional database to investigate outcomes of prophylactic muscle flaps in high-risk patients who underwent prosthetic bypasses involving femoral anastomosis. METHODS: We utilized ACS-NSQIP database 2005-2021 to identify all elective inflow and infrainguinal bypasses that involve femoral anastomoses. Only high-risk patients for poor incisional healing who underwent prosthetic conduit bypasses were selected. A 1:3 propensity-matching was performed to obtain two comparable studied groups between those with (FLAP) and without prophylactic muscle flaps (NOFLAP) based on demographics and comorbidities. 30-day postoperative outcomes were compared. RESULTS: Among 35,011 NOFLAP, 990 of them were propensity-matched to 330 FLAP. There was no significant difference in 30-day mortality, MACE, pulmonary, or renal complications. FLAP was associated with higher bleeding requiring transfusion, longer operative time, and longer hospital stay. FLAP also had higher overall wound complications (15.2% vs. 10.6%; p = 0.03), especially deep incisional infection (4.9% vs. 2.4%; p = 0.04). CONCLUSION: Prophylactic muscle flap for prosthetic bypasses involving femoral anastomosis in high-risk-for-poor-healing patients does not appear to mitigate 30-day wound complications. Caution should be exercised with this practice and more long-term data should be obtained to determine whether prophylactic flaps decrease the incidence of graft infection.
RESUMEN
This case report presents the management of a 69-year-old man with an extensive history of peripheral vascular disease including 2 previous failed right femoral to distal bypasses and a left above-the-knee amputation who presented with right lower extremity rest pain and non-healing shin ulcers. A redo bypass was performed for limb salvage via the obturator foramen to avoid his extensively scarred femoral region. The postoperative course was uneventful and the bypass remained patent in the early period. This case demonstrates the usefulness of the obturator bypass to provide revascularization and avoid amputation in a patient with chronic limb-threatening ischemia and multiple failed bypasses.

We report the case of a 66-year-old man who had been emergently transferred to our institution with hemoptysis and hemodynamic instability. His computed tomography findings were consistent with the presence of an aortobronchial fistula. The patient had undergone open repair of coarctation of aorta via thoracotomy 20 years previously, and he was not deemed a suitable candidate for open repair. He was successfully treated with thoracic endovascular aortic repair with successful exclusion of the fistula. The patient was discharged home, and the subsequent follow-up imaging study at 12 months showed the graft in a stable position without evidence of infection, pseudoaneurysm, or endoleak. This case has demonstrated the successful use of thoracic endovascular aortic repair for urgent management of an aortobronchial fistula.
RESUMEN
Thoracic outlet syndrome commonly presents with the neurogenic subtype and can be caused in rare circumstances by an anatomic abnormality such as a cervical rib, for which surgical excision is the mainstay of management. An inadequately excised first or cervical rib can result in recurrent symptoms. We have reported the case of a 30-year-old woman who had presented with symptoms of right recurrent arterial and neurogenic thoracic outlet syndrome. She underwent repeat right-sided first rib and cervical rib resection with brachial plexus neural lysis and right carotid-axillary bypass via a combined supraclavicular and infraclavicular approach. At 12 months of follow-up, improvement in her symptoms was noted.
RESUMEN
BACKGROUND: Numerous angiography-based peripheral arterial disease classification schemes have been developed to stratify severity of preoperative patient disease, but few studies have correlated angiography-based anatomic classification schemes to postoperative outcomes. This study examined whether a proposed pre-operative angiography scoring system was predictive of outcomes after isolated common femoral endarterectomy with profundaplasty (CFEP). METHODS: A retrospective review was conducted of patients treated with isolated CFEP for claudication and/or rest pain at a single institution from 2016-19. Pre-operative angiograms were assessed quantitatively by 4 blinded surgeons across 3 domains: profunda stenosis, profunda disease length, and outflow disease severity. Table I describes the proposed angiography scoring system. Internal consistency reliability of rater scores was calculated using Cronbach alpha. Outcomes included clinical improvement, further interventions, major amputations, mortality, and mean increase in ankle-brachial index (ABI) at 30 days, and 6 months. McNemar tests, between-group t-tests, Pearson correlations, and linear regression were used. RESULTS: Clinical Outcomes 88% of patients (n = 22) had clinical improvement at 30 days; the remaining 12% of patients (n = 3) required further interventions. One patient (4%) required major amputation between 30 days and 6 months for recurrence of rest pain that had initially resolved after isolated CFEP. There was 0% mortality during the study period. Mean ABI increased by 0.15 ± 0.21 at 30 days, and by 0.06 ± 0.21 at 6 months. Angiography Scoring System Profunda stenosis score was associated with clinical improvement at 6 months (P = 0.04). A profunda stenosis score of ≥2.6 was strongly associated with 6-month clinical improvement (64% of those ≥ 2.6 improved, versus 15% of those <2.6, P = 0.15). Profunda stenosis score was associated with ABI improvement at 30 days (r = 0.73, P = 0.01) and 6 months (r = 0.82, P = 0.007). Profunda disease length score was associated with clinical improvement at 30 days (P = 0.002). 100% of patients with a profunda disease length score of ≥1.5 clinically improved at 30 days, versus 67% of those with <1.5 (P = 0.04). Angiography scores were not found to be associated with further intervention, major amputation, or mortality. Cronbach alpha for profunda stenosis, profunda disease length, and outflow severity scores were 0.90, 0.90, and 0.79, respectively, indicating strong internal consistency. CONCLUSIONS: This institutional angiography scoring system successfully predicts clinical improvement following CFEP. Higher profunda stenosis and profunda disease length scores were most predictive of operative success within 6 months. Future validation studies will investigate these outcomes in a larger population, and over a longer period.

BACKGROUND: Recently, open abdominal aortic aneurysm (AAA) repair (OSR) has become less common and will often be reserved for patients with more complex aortic anatomy. Despite improvements in patient management, the reduced surgical volume has raised concerns for potentially worsened outcomes in the contemporary era (2014-2019) compared with an earlier era in which OSR was more widely practiced (2005-2010). In the present study, we compared the 30-day outcomes of open AAA repair between these two eras. METHODS: The American College of Surgeons National Quality Improvement Program general database was queried for open AAA repair using the Current Procedural Terminology and International Classification of Diseases, 9th and 10th, codes. The cases were stratified into two groups by operation year: 2005 to 2010 (early) and 2014 to 2019 (contemporary). In each era, the cases were further divided into elective and ruptured groups. The 30-day outcomes, including mortality, major morbidity, postoperative sepsis, and unplanned reoperation, were compared between the contemporary and early eras in the elective and ruptured groups. Preoperative variables with a P value <.25 were adjusted for in the multivariate analysis. RESULTS: In the contemporary and early eras, 3749 and 3798 patients had undergone elective OSR and 1148 and 907 had undergone ruptured OSR, respectively. These samples were of similar sizes owing to the National Quality Improvement Program sampling process and our relatively strict inclusion criteria. In the contemporary era, fewer patients were elderly and fewer were smokers or had hypertension or dyspnea in the elective and rupture cohorts. More patients had had American Society of Anesthesiologists class >3 in the elective contemporary era (39% vs 24%; P < .0001). The contemporary elective repair group demonstrated increased 30-day mortality (3.7% vs 3.2%; adjusted odds ratio [aOR], 1.36; P = .006), major adverse cardiac events (5.7% vs 3.4%; aOR, 1.87; P < .0001), and bleeding requiring transfusion (58.5% vs 13.7%; aOR, 8.96; P < .0001). The incidence of pulmonary complications (12.1% vs 15.2%; aOR, 0.80; P = .02) and sepsis (3.7% vs 8.4%; aOR, 0.47; P < .0001) had decreased in the contemporary era, with a similar rate of unplanned reoperations (8.4% vs 7.7%; aOR, 1.16; P = .09). The incidence of renal complications in the contemporary era had increased, with a statistically significant difference. However, the absolute increase of <0.5% was likely not clinically relevant (5.5% vs 5.1%; aOR, 1.23; P = .049). In the ruptured cohort, contemporary repair was associated with increased 30-day mortality (41.4% vs 40%; aOR, 1.53; P < .0001), major adverse cardiac events (25.8% vs 12.8%; aOR, 2.49; P < .0001), and bleeding requiring transfusion (88.2% vs 27%; aOR, 23.03; P < .0001). The incidence of pulmonary complications (36.9% vs 48.1%; aOR, 0.67; P < .0001), sepsis (14.6% vs 23%; aOR, 0.75; P = .03), and unplanned reoperations (18.1% vs 22.7%; aOR, 0.74; P = .008) had decreased in the contemporary OSR group. No differences were detected in the incidence of renal complications. CONCLUSIONS: The 30-day mortality has worsened after open AAA repair in the elective and rupture settings despite the improvements in perioperative management over the years. These complications likely stem from increased bleeding events and major cardiac events, which were increased in the contemporary era.

OBJECTIVE: The optimal management of infected abdominal aortic grafts is complete surgical excision plus in situ or extra-anatomic revascularization in patients who can tolerate this morbid operation. In addition to using age and the presence of comorbidities for risk assessment, physicians form a global clinical impression when deciding whether to offer excision or to manage conservatively. Functional status is a distinct objective measure that can inform this decision. This study examines the relative impact of age and functional status on outcomes of infected abdominal aortic graft excision to guide surgical decision-making. METHODS: Current Procedural Terminology code 35907 was used to identify patients undergoing excision of infected abdominal aortic graft in the 2005 to 2017 American College of Surgeons - National Surgical Quality Improvement Program (NSQIP) database. Patients were stratified by the upper age quartile (75 years old) as a cutoff, and then by functional status, independent vs dependent (as defined by NSIQIP). The patients were then stratified into four groups: Younger (<75)/Independent, Younger (<75)/Dependent, Older (≥75)/Independent, and Older (≥75)/Dependent. Outcomes measured included 30-day mortality and major organ-system dysfunction. RESULTS: There were 814 patients who underwent infected abdominal aortic graft excision: 508 patients (62%) were Younger/Independent, 89 patients (11%) were Younger/Dependent, 176 patients (22%) were Older/Independent, and 41 patients (5%) were Older/Dependent. There was no statistically significant difference in 30-day mortality for Younger/Dependent (odds ratio [OR], 1.66; 95% confidence interval [CI], 0.90-3.09; P = .536) or Older/Independent (OR, 1.31; 95% CI, 0.78-2.19; P = .311) patients when compared with Younger/Independent patients, which suggests that neither old age nor dependent functional status by itself adversely affects mortality. However, when both factors were present, Older/Dependent patients had three times higher mortality when compared with Younger/Independent patients (41.5% vs 13.4%, respectively; OR, 3.13; 95% CI, 1.46-6.71; P = .003). Furthermore, as long as patients presented with independent functional status, old age by itself did not adversely affect major organ-system dysfunction (ORs for Older/Independent vs Younger/Independent were 0.76 [P = .454], 1.04 [P = .874], and 0.90 [P = .692] for cardiac, pulmonary, and renal complications, respectively). On the contrary, even in younger patients, dependent functional status was significantly associated with higher pulmonary complications (Younger/Dependent vs Younger/Independent: OR, 2.22; 95% CI, 1.33-3.73; P = .002) and higher rates of unplanned reoperation (OR, 2.67; 95% CI, 1.62-4.41; P < .0001). CONCLUSIONS: Dependent functional status has significant association with adverse outcomes after excision of infected abdominal aortic grafts, whereas old age alone does not. Therefore, this procedure could be considered in appropriately selected elderly patients with otherwise good functional status. However, caution should be applied in dependent patients regardless of age due to the risk of pulmonary complications.

BACKGROUND: Mega-fistulae are generalized aneurysmal dilations of a high flow (1500-4000 mL/min) autogenous arteriovenous (AV) access which may result in hemorrhage and/or high-output cardiac failure. Current treatments include ligation, ligation with prosthetic jump graft, and imbrication; however, these may not be suitable for advanced disease, or may result in loss of functioning access, poor cosmesis, or recurrence. We describe our early experience with a technique of complete mega-fistula resection and replacement with an early use prosthetic graft that both maintains existing AV access and eliminates the need for long-term catheter (LTC) placement; including lessons learned. METHODS: A single-center, retrospective review of medical records was conducted from March 2018-February 2021. Outcomes were technical success, LTC use, time to cannulation, and complications. Mega-fistulae were completely resected from the proximal to distal aneurysmal segment, including all pseudoaneurysms, followed by tunneling a prosthetic graft (Propaten later converted to Acuseal; W.L. Gore Assoc.) with an end-to-end anastomosis to the remaining arterial and venous ends of the previous AV access. RESULTS: We had 100% immediate technical success (n=12). Pre-operative long-term catheters were placed in all eight Propaten patients; one was already placed in an Acuseal patient. Average time to cannulation was six weeks with Propaten and 4.5 days with Acuseal. At 30 days, three Propaten patients developed complications including one instance of skin necrosis, one seroma, and one hematoma. Two Acuseal patients developed complications including one central venous occlusion (CVO) and one graft infection. Of the six patients with long-term follow-up, five continue to use their access, however, two required thrombectomies and central venous angioplasties. One patient required a new contralateral access due to CVO. CONCLUSIONS: Complete mega-fistula resection and replacement with Acuseal graft maintains existing AV access and may eliminate the need for long-term catheter placement. Our early experience with this technique is encouraging, but further follow-up is required to determine the durability of this approach.

OBJECTIVE: Although fenestrated endovascular aneurysm repair (FEVAR) has been associated with lower morbidity and mortality than open surgical repair (OSR) in juxtarenal aneurysms (JAAA), there is a paucity of data in the literature comparing outcomes of the approaches specifically in patients with chronic renal insufficiency (CRI). We hypothesized that benefits of FEVAR over OSR observed in the general patient population may be diminished in CRI patients due to their heightened vulnerability to renal dysfunction stemming from contrast-induced nephropathy. This study compares 30-day outcomes between FEVAR and OSR for JAAA in patients with non-dialysis dependent CRI. METHODS: All adults with estimated glomerular filtration rate (eGFR) < 60 mL/min (but not requiring dialysis) undergoing elective, non-ruptured JAAA repairs were identified in the American College of Surgeons - National Surgical Quality Improvement (ACS-NSQIP) Targeted EVAR and AAA databases from 2012-2018. JAAA were identified by recorded proximal aneurysm extent. FEVAR patients were identified in the Targeted EVAR database as those receiving the "Cook Zenith Fenestrated" endograft. OSR cases were defined as those that required proximal clamp positions "above one renal" or "between SMA & renals." Infra-renal or supra-celiac proximal clamp placement, or cases involving concomitant renal/visceral revascularization were excluded. Thirty-day outcomes including mortality, major adverse cardiovascular events (MACE), pulmonary, and renal complications were compared between FEVAR and OSR groups. RESULTS: There were 284 patients with CRI who underwent elective repair of JAAA (FEVAR: 89; OSR: 195). FEVAR patients were significantly older than those undergoing OSR (77.3±7.2 vs. 74.2±7.7, P=0.001) and less likely to be smokers (25.8% vs 42.1%; Pâ¯=â¯0.009). Other baseline demographic and pre-operative parameters were comparable between the two groups.Multivariable analysis revealed no significant difference between FEVAR and OSR in 30-day mortality (4.5% vs 4.6%; OR=1.22; 95% CI=0.35 - 4.22; P=0.753) or unplanned re-operation (4.5% vs 5.1%; OR=0.78; 95% CI=0.22 - 2.70; P=0.693). Patients undergoing FEVAR had significantly fewer pulmonary complications (3.4% vs 18.5%; OR=0.12; 95% CI=0.03 - 0.42; P<0.001) and renal dysfunction (3.4% vs 11.8%; OR 0.24 95% CI=0.07 - 0.86; P=0.029) compared to OSR. FEVAR was also associated with significantly shorter ICU and hospital lengths of stay (ICU stay: 0 days vs 3 days, P<0.0001; hospital stay: 3 days vs 8 days, P<0.0001). CONCLUSION: For patients with chronic renal insufficiency, FEVAR offered improved perioperative renal morbidity compared to OSR without a corresponding mortality benefit. Future studies will be required to determine long term outcomes of this procedure in this vulnerable population.

OBJECTIVE: Open surgical repair (OSR) of abdominal aortic aneurysms (AAAs) has often been reserved in contemporary practice for complex aneurysms requiring a suprarenal or supraceliac proximal clamp level. The present study investigated the associated 30-day outcomes of different proximal clamp levels in OSR of complex infrarenal/juxtarenal AAA in patients with normal renal function and those with chronic renal insufficiency (CRI). METHODS: All patients undergoing elective OSR of infrarenal and juxtarenal AAA were identified in the American College of Surgeons National Surgical Quality Improvement Program-targeted AAA database from 2012 to 2018. The patients were stratified into two cohorts (normal renal function [estimated glomerular filtration rate, ≥60 mL/min] and CRI [estimated glomerular filtration rate, <60 mL/min and no dialysis]) before further substratification into groups by the proximal clamp level (infrarenal, inter-renal, suprarenal, and supraceliac). The 30-day outcomes, including mortality, renal and pulmonary complications, and major adverse cardiovascular event rates, were compared within each renal function cohort between proximal clamp level groups using the infrarenal clamp group as the reference. Supraceliac clamping was also compared with suprarenal clamping. RESULTS: A total of 1284 patients with normal renal function and 524 with CRI were included in the present study. The proximal clamp levels for the 1808 patients were infrarenal for 1080 (59.7%), inter-renal for 337 (18.6%), suprarenal for 279 (15.4%), and supraceliac for 112 (6.2%). In the normal renal function cohort, no difference was found in 30-day mortality with any clamp level. Increased 30-day acute renal failure was only observed in the supraceliac vs infrarenal clamp level comparison (5.9% vs 1.5%; adjusted odds ratio [aOR], 3.97; 95% confidence interval [CI], 1.04-5.18; P = .044). In the CRI cohort, supraceliac clamping was associated with an increased rate of renal composite complications (22.7% vs 5.6%; aOR, 8.81; 95% CI, 3.17-24.46; P < .001) and ischemic colitis (13.6% vs 3.0%; aOR, 4.78; 95% CI, 1.38-16.62; P = .014) compared with infrarenal clamping and greater 30-day mortality (13.6% vs 2.4%; aOR, 6.00; 95% CI, 1.14-31.55; P = .034) and renal composite complications (22.7% vs 10.8%; aOR, 2.87; 95% CI, 1.02-8.13; P = .047) compared with suprarenal clamping. Suprarenal clamping was associated with greater renal dysfunction (10.8% vs 5.6%; aOR, 2.77; 95% CI, 1.08-7.13; P = .035) compared with infrarenal clamping, with no differences in mortality. No differences were found in 30-day mortality or morbidity for inter-renal clamping compared with infrarenal clamping in either cohort. No differences were found in major adverse cardiovascular events with higher clamp levels in either cohort. CONCLUSIONS: In elective OSR of infrarenal and juxtarenal AAAs for patients with CRI, this study found a heightened mortality risk with supraceliac clamping and increased renal morbidity with suprarenal clamping, though these effects were not present for patients with normal renal function. Every effort should be made to keep the proximal clamp level as low as possible, especially in patients with CRI.

BACKGROUND: It is often hypothesized that failed prior endovascular intervention could adversely affect the outcome of subsequent infrainguinal bypass in the corresponding limb. However, this perception is not well supported in the literature because of conflicting data. The aim of this study is to address this controversial issue via analysis of a multicenter prospectively collected database. METHODS: Patients who underwent infrainguinal bypass for chronic limb threatening ischemia (CLTI) were identified in the targeted American College of Surgeons National Surgical Quality Improvement Program database from 2011 to 2017. These patients were stratified into 4 groups: first time femoral-popliteal bypass, femoral-popliteal bypass after failed prior endovascular revascularization, first time femoral-tibial bypass, and femoral-tibial bypass after failed prior endovascular revascularization. Thirty-day outcomes including mortality, graft patency, major amputations, and major organ dysfunction were measured. RESULTS: We identified 7,044 patients who underwent surgical bypasses for CLTI. Patients were mostly well matched among the 4 groups except for differences in sex, hypertension, and preoperative renal function. In terms of major adverse cardiovascular events and major adverse limb events, femoral-popliteal or femoral-tibial bypasses after failed prior endovascular intervention had comparable 30-day outcomes to first-time bypasses. However, patients with failed prior endovascular intervention had increased rates of postoperative wound infection, required significantly more blood transfusions, and had longer operative time. CONCLUSIONS: Failed prior endovascular intervention does not adversely affect 30-day outcomes of subsequent infrainguinal bypass surgery in mortality, limb salvage, or other major cardiovascular complications.

OBJECTIVES: Widespread adoption of endovascular therapy for the treatment of chronic limb-threatening ischemia has transformed the field of vascular surgery. In this modern era, we aimed to define where open surgical interventions are of greatest benefit for limb salvage. METHODS: Patients who underwent interventions for chronic limb-threatening ischemia were identified in the vascular-targeted lower extremity National Surgical Quality Improvement Program database for open surgical interventions (OPEN) and endovascular surgical interventions (ENDO) from 2011 to 2017. Patients were further stratified based on the criteria of chronic limb-threatening ischemia (rest pain or tissue loss), and the location of the diseased arteries (femoropopliteal or tibioperoneal). The main outcomes measured included 30-day mortality, amputation, and major adverse cardiovascular events. RESULTS: A total of 17,193 patients were revascularized for chronic limb-threatening ischemia: 10,532 were OPEN and 6661 were ENDO. OPEN had higher 30-day mortality, major adverse cardiovascular events, pulmonary, renal dysfunction, and wound complications. However, OPEN resulted in significantly lower 30-day major amputation (3.8% vs. 5.0%, odds ratio (OR): 0.83 [0.72-0.97], P = .018). Subgroup analysis revealed a higher mortality rate in OPEN was observed only in tibioperoneal intervention for tissue loss. Major adverse cardiovascular event was higher in OPEN for most subgroups. OPEN for patients with tissue loss had significantly lower amputation rate than ENDO in both femoropopliteal and tibioperoneal subgroups (3.7% vs. 5.1%, OR: 0.76 [0.59-0.98], P = .036, and 4.7% vs. 6.6%, OR: 0.74 [0.57-0.96], P = .024, respectively). The benefit of open surgery in reducing the amputation rate was not seen in patients with rest pain. CONCLUSIONS: Open surgical intervention is associated with significantly better limb salvage than endovascular intervention in patients with tissue loss. Surgical options should be given more emphasis as the first-line option in this cohort of patients unless the cardiopulmonary risk is prohibitive.

OBJECTIVE: Endovascular repair of juxtarenal abdominal aortic aneurysms (JAAAs) with fenestrated grafts (fenestrated endovascular aneurysm repair [FEVAR]) has been reported to decrease operative mortality and morbidity compared with open surgical repair (OSR). However, previous comparisons of OSR and FEVAR have not necessarily included patients with comparable clinical profiles and aneurysm extent. Although FEVAR has often been chosen as the first-line therapy for high-risk patients such as the elderly, many patients will not have anatomy favorable for FEVAR. At present, a paucity of data has examined the operative outcomes of OSR in elderly patients for JAAAs relative to FEVAR. Therefore, we chose to perform a propensity-matched comparison of OSR and FEVAR for JAAA repair in patients aged ≥70 years. METHODS: Patients aged ≥70 years who had undergone elective nonruptured JAAA repairs from 2012 to 2018 were identified in the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) targeted endovascular aneurysm repair (EVAR) and AAA databases. Patients who had undergone FEVAR were identified in the targeted EVAR database as those who had received the Cook Zenith Fenestrated endograft (Cook Medical, Bloomington, Ind). Because our study specifically examined JAAAs, those patients who had undergone OSR with supraceliac proximal clamping or concomitant renal/visceral revascularization were excluded. A 1:1 propensity-match algorithm matched the OSR and FEVAR patients by preoperative clinical and demographic characteristics, operative indications, and aneurysm extent. The 30-day outcomes, including mortality, major adverse cardiovascular events, and pulmonary and renal complications, were compared between the propensity-matched OSR and FEVAR groups. RESULTS: A 1:1 propensity match was achieved, and the final analysis included 136 OSR patients and 136 FEVAR patients. No significant differences were found in 30-day mortality (4.4% vs 3.7%; odds ratio [OR], 1.21; 95% confidence interval [CI], 0.36-4.06; P = .759) between the OSR and FEVAR groups. OSR was associated with a higher incidence of major adverse cardiovascular events compared with FEVAR; however, the trend was not statistically significant (8.1% vs 3.7%; OR, 2.31; 95% CI, 0.78-6.82; P = .131). Compared with FEVAR, the OSR group had significantly greater rates of pulmonary complications (19.1% vs 3.7%; OR, 6.19; 95% CI, 2.30-16.67; P < .001) and renal complications (8.1% vs 2.2%; OR, 3.90; 95% CI, 1.06-14.31; P = .040). CONCLUSIONS: In the samples assessed in the present study, the results with OSR of JAAAs in the elderly did not differ from those of FEVAR with respect to 30-day mortality despite a greater incidence of pulmonary and renal complications. Although FEVAR should remain the first-line therapy for JAAAs in elderly patients, OSR might be an acceptable alternative for select patients with anatomy unfavorable for FEVAR.

OBJECTIVE: Vascular surgical groin wound infection (VS-GWI) has multiple causes and frequently is manifested as a limb- or life-threatening problem, resulting in significant morbidity and mortality. For patients undergoing operative extirpation, in situ repair, extra-anatomic bypass, or ligation can be used; however, limited data exist describing comparative results of the different operative choices or conduit subtypes. Therefore, we sought to describe our experience with management of VS-GWI and to detail outcomes of the different strategies. METHODS: Patients (2003-2017) undergoing surgical treatment of VS-GWI (Szilagyi grade III) secondary to primary infectious arteritis or infected pseudoaneurysm after percutaneous intervention as well as previous prosthetic graft placement were reviewed. The primary end point was major adverse limb events (MALEs; major amputation, graft occlusion, or unplanned reintervention). Secondary end points included 30-day mortality, wound healing, amputation-free survival (AFS), and all-cause mortality. Cox proportional hazards modeling was used to determine relative risk of end points; Kaplan-Meier methodology was employed to estimate freedom from outcomes. RESULTS: There were 149 patients (age, 65 ± 11 years; body mass index, 27 ± 6 kg/m2; 70% male; 32% diabetes) identified, of whom 120 (81%) had unilateral and 29 (19%) had bilateral VS-GWI. Indications included infected prosthetic bypass (88% [n = 131]; infrainguinal, 107; suprainguinal, 24) and primary infectious femoral artery complications (12% [n = 18]). A majority underwent single-stage operations (87% [n = 129]). In situ reconstruction occurred in 87% (n = 129); 9% (n = 13) underwent ligation, and 6% (n = 7) received extra-anatomic revascularization. Autogenous conduit was used most commonly (68% [n = 101/149]; 88% single stage), of which 81% (n = 80) were femoral vein. The remaining patients received cadaveric (15% [n = 23]; 87% single stage) or prosthetic (8% [n=12]; 67% single stage) grafts. Adjunctive myocutaneous flap was used in 37% (n = 54). Length of stay was 19 ± 15 days and 30-day mortality was 7% (n = 10), with no difference between conduit repair types. All femoral wounds healed (mean follow-up, 17 ± 11 months); however, 33% (n = 49) underwent reoperation (unplanned graft reintervention, 33%; graft occlusion, 16%; wound débridement, 15%; major amputation, 11%). Reinfection occurred in 17% (n = 27), with no difference between groups. MALE rate was 22% (n = 33; most were arterial reinterventions, 19%), with no difference in single-stage vs multistage, in situ vs extra-anatomic, or autogenous vs nonautogenous conduit strategies Predictors of MALE included younger age (hazard ratio [HR], 1.6 per decade; 95% confidence interval [CI], 1.1-2.5; P = .02) and lower body mass index (<25 kg/m2; HR, 1.6 per BMI category; 95% CI, 1.1-2.5; P = .02). Overall, 1- and 3-year freedom from MALE, AFS, and survival were as follows: MALE, 74% ± 5% and 63% ± 6%; AFS, 68% ± 4% and 58% ± 5%; survival, 78% ± 3% and 70% ± 4%. Autogenous conduit use was associated with better survival (HR, 0.5; 95% CI, 0.3-0.8; 1-year: 83% ± 4% vs nonautogenous, 78% ± 4%; 3-year: 68% ± 8% vs 53% ± 9%; log-rank, P = .006). CONCLUSIONS: An individualized approach to operative strategy and conduit choice leads to comparable outcomes in this challenging group of patients. VS-GWI can be safely managed with in situ, autogenous reconstruction in a majority of patients with acceptable mortality, excellent wound healing rates, and improved overall survival. However, a significant proportion of patients experience reinfection and MALEs, the preponderance of which are arterial reintervention, mandating need for close follow-up and graft surveillance.

Paget-Schroetter syndrome is a form of primary venous thoracic outlet syndrome whereby thrombosis of the subclavian vein is instigated by repeated and vigorous overhead activity of the arm. We describe a 35-year-old pregnant white woman at 8 weeks' gestation, a competitive swimmer by profession, who was diagnosed with a left upper extremity thrombus. First rib resection through an infraclavicular approach was performed 1 week after percutaneous pharmacomechanical thrombectomy. Repeated venography demonstrated residual thrombus requiring percutaneous pharmacomechanical thrombectomy with balloon venoplasty. We present a challenging case with focus on the unique diagnostic evaluation and management of pregnant patients with this condition.
RESUMEN
BACKGROUND: Thoracic endovascular aortic repair (TEVAR) has become a mainstay of therapy for acute and chronic type B aortic dissection (TBAD). Dynamic aortic morphologic changes, untreated dissected aorta, and persistent false lumen perfusion have significant consequences for reintervention after TEVAR for TBAD. However, few reports contrast differences in secondary aortic intervention (SAI) after TEVAR for TBAD or describe their influence on mortality. This analysis examined incidence, timing, and types of SAI after TEVAR for acute and chronic TBAD and determined their impact on survival. METHODS: All TEVAR procedures for acute and chronic TBAD (2005-2016) were retrospectively reviewed. Patients with staged (<30 days) or concomitant ascending aortic arch repair or replacement were excluded. Acuity was defined by symptom onset (0-30 days, acute; >30 days, chronic). SAI procedures were grouped into open (intended treatment zone or remote aortic site), major endovascular (TEVAR extension or endograft implanted at noncontiguous site), and minor endovascular (side branch or false lumen embolization) categories. Kaplan-Meier methodology was used to estimate freedom from SAI and survival. Cox proportional hazards were used to identify SAI predictors. RESULTS: TEVAR for TBAD was performed in 258 patients (acute, 49% [n = 128]; chronic, 51% [n = 130]). Mean follow-up was 17 ± 22 months with an overall SAI rate of 27% (n = 70; acute, 22% [28]; chronic, 32% [42]; odds ratio, 1.7; 95% confidence interval, 0.9-2.9; P = .07]. Median time to SAI was significantly less after acute than after chronic dissection (0.7 [0-12] vs 7 [0-91] months; P < .001); however, freedom from SAI was not different (1-year: acute, 67% ± 4%, vs chronic, 68% ± 5%; 3-year: acute, 65% ± 7%, vs chronic, 52% ± 8%; P = .7). Types of SAI were similar (acute vs chronic: open, 61% vs 55% [P = .6]; major endovascular, 36% vs 38% [P = .8]; minor endovascular, 21% vs 21% [P = 1]). The open conversion rate (either partial or total endograft explantation: acute, 10% [13/128]; chronic, 15% [20/130]; P = .2) and incidence of retrograde dissection (acute, 6% [7/128]; chronic, 4% [5/130]; P = .5) were similar. There was no difference in survival for SAI patients (5-year: acute + SAI, 55% ± 9%, vs acute without SAI, 67% ± 8% [P = .3]; 5-year: chronic + SAI, 72% ± 6%, vs chronic without SAI, 72% ± 7% [P = .7]). Factors associated with SAI included younger age, acute dissection with larger maximal aortic diameter at presentation, Marfan syndrome, and use of arch vessel adjunctive procedures with the index TEVAR. Indication for the index TEVAR (aneurysm, malperfusion, rupture, and pain or hypertension) or remote preoperative history of proximal arch procedure was not predictive of SAI. CONCLUSIONS: SAI after TEVAR for TBAD is common. Acute TBAD has a higher proportion of early SAI; however, chronic TBAD appears to have ongoing risk of remediation after the first postoperative year. SAI types are similar between groups, and the occurrence of aorta-related reintervention does not affect survival. Patients' features and anatomy predict need for SAI. These data should be taken into consideration for selection of patients, device design, and surveillance strategies after TEVAR for TBAD.

BACKGROUND: Aortic coarctation (AC) is most commonly identified in pediatric patients; however, adults can present with late sequelae of untreated coarctation or complications of prior open repair. To date, there are limited data about the role of thoracic endovascular aortic repair (TEVAR) in this group of patients. The purpose of this analysis was to describe our experience with management of adult coarctation patients using TEVAR. METHODS: All TEVAR patients treated for primary coarctation or late sequelae of previous open repair (eg, pseudoaneurysm, recurrent coarctation or anastomotic stenosis related to index open coarctation repair) were reviewed. Demographics, comorbidities, procedure-related variables, postoperative outcomes, and reintervention were recorded. Computed tomography centerline assessments of endograft morphology were completed to delineate stent anatomy at the coarctation site. Survival and reintervention were estimated using life-table analysis. RESULTS: A total of 21 patients were identified (median age, 46 years [range, 33-71 years]; 67% male [n = 14]). Nine patients (43%) were treated for symptomatic primary (n = 6) or recurrent (n = 3) coarctation. Other indications included degenerative thoracic aneurysm (n = 6), pseudoaneurysm (n = 4), and dissection (n = 2). Technical success was 100% (95% confidence interval [CI], 84%-100%). No 30-day mortality or paraplegia events occurred; however, two patients (10%) experienced postoperative nondisabling stroke. In primary or recurrent coarctation patients with available computed tomography imaging (n = 8 of 9), nominal stent graft diameters were achieved proximal and distal to the coarctation (range, -0.4 to -1.2 mm of desired final stent diameter). Specific to the coarctation site, there was a significant increase in aortic diameter after TEVAR (before stenting, 11.5 [95% CI, 6.8-12.3] mm; after stenting, 15 [95% CI, 13.7-15.7] mm; P = .004). Concurrently, systolic arterial blood pressure at time of discharge was significantly lower (before stenting: 147 mm Hg; 95% CI, 137-157 mm Hg; after stenting: 124 mm Hg; 95% CI, 118-134 mm Hg; P = .02). For all patients, median clinical follow-up time was 8 months (interquartile range, 3-13 months; range, 1-106 months). Three endoleaks were detected, all of which were type II related to left (n = 2) or aberrant (n = 1) subclavian arteries. Four patients (19%) underwent reintervention (median time, 7 months; range, 2-12 months), with three of four being subclavian artery embolization; one was an aortic root replacement for ascending aneurysm with bicuspid aortic valve. One-year freedom from reintervention was 78% ± 9% (95% CI, 42%-92%). The 1- and 3-year survival was 95% ± 5% (95% CI, 71%-99%). One late death was related to complications from pre-existing congenital heart disease. CONCLUSIONS: Adult AC patients can be treated safely with TEVAR, and the annular constriction of an AC can be successfully dilated by the stent graft. Given these findings, a greater number of patients with longer term follow-up is warranted to further define the role of TEVAR in the management of adult AC patients.
