RESUMO

OBJECTIVE: Primary arteriovenous access such as radiocephalic and brachiocephalic fistulas are initial choices for creating vascular access in dialysis patients. When neither of these choices is an option, upper arm arteriovenous graft or brachiobasilic transposition is recommended. Although primary fistula is better than prosthetic graft for suitable patients, there is little data to guide the best treatment strategy in the absence of suitable vein for primary access creation. This study identifies factors that influence patency rates and compares outcomes of patients treated with brachiobasilic fistula vs upper arm graft in patients who have failed forearm access or are not candidates for primary access. METHODS: A prospectively maintained database of patients with dialysis-dependent renal failure from 2010 to 2022 was analyzed. Primary, primary assisted, and secondary patency rates were calculated. Incidence rates of complications and reinterventions were compared. RESULTS: There were 148 patients with brachiobasilic fistulas and 157 patients with upper arm grafts. The graft group was older (70.1 ± 14.7 vs 62.5 ± 14.6 years; P = .003) and had a higher incidence of pacemakers (11.9% vs 4.1%; P = .005). Brachiobasilic fistulas had higher 6-month (77.0% vs 64.3%; P = .02) and 1-year (68.2% vs 55.4%; P = .03) primary-assisted patency. Secondary patency rates were better for upper arm grafts at 1-year (82.2% vs 72.3%; P = .05). Access complications of non-maturation and aneurysm were higher in basilic vein transposition (21.6% vs 1.3%; P < .0001; 15.5% vs 6.4%; P = .017). Grafts had higher rates of occlusion (58.0% vs 25.7%; P < .0001). In terms of interventions, upper arm grafts had higher rates of thrombectomy (50.3% vs 18.9%; P < .0001), but there was no difference seen in angioplasty, stent, surgical revision, or steal procedures. Basilic vein transpositions had longer time to cannulation (104.6 ± 81.1 vs 32.5 ± 22.4 days; P < .0001), longer total catheter days (251.1 ± 181.7 vs 72.9 ± 56.3 days; P < .0001), and higher number of procedures to aid maturity (0.7 ± 0.7 vs 0.1 ± 0.3; P < .0001). CONCLUSIONS: In this retrospective analysis, when forearm access or primary arteriovenous access is not an option, basilic vein transposition and upper arm grafts have fairly equivalent primary patency. Primary assisted patency is slightly better in basilic vein fistulas, but secondary patency is better in upper arm grafts at 1 year. Basilic fistulas also had longer time to cannulation, longer total catheter days, and more procedures to aid maturity.

RESUMO

BACKGROUND: Endovascular repair of blunt thoracic aortic injury (BTAI) has dramatically reduced the morbidity and mortality of intervention. Injuries requiring zone 2 coverage of the aorta traditionally require left subclavian artery (LSA) sacrifice or open revascularization. Furthermore, these injuries are associated with an increased risk of in-hospital mortality and long-term morbidity. Here we report 1-year outcomes of total endovascular repair of BTAI with the GORE® TAG® Thoracic Branch Endoprosthesis for LSA preservation. METHODS: Across 34 investigative sites, 9 patients with BTAI requiring LSA coverage were enrolled in a nonrandomized, prospective study of a single-branched aortic endograft. The thoracic branch endoprosthesis device allows for graft placement proximal to the LSA and incorporates a single side branch for LSA perfusion. RESULTS: This initial cohort included 8 male and 1 female patient with a median age of 43 (22, 76) and 12 months of follow-up. Five total years of follow-up are planned. All participants had grade 3 BTAI. All procedures took place between 2018 and 2019. The median injury severity score was 2 (0, 66). The median procedure time was 109 min (78, 162). All aortic injuries were repaired under general anesthesia and with heparinization. A spinal drain was used in one patient. Post-deployment balloon angioplasty was conducted in one case at the distal landing zone. There was one asymptomatic LSA branch occlusion 6 months after repair. It was attributed to the purposeful proximal deployment of the branch stent to accommodate an early vertebral takeoff. The occlusion did not require revascularization. There were no strokes, mortalities, or aortic adverse events (migration, endoleak, native aortic expansion, dissection, or thrombosis) through 12 months of follow-up. CONCLUSIONS: Initial cohort outcomes suggest that endovascular repair of zone 2 BTAI is feasible and has favorable outcomes using the thoracic branch device with LSA preservation. Additional cases and longer-term follow-up are required for a definitive assessment of the device's safety and durability in traumatic aortic injuries.

RESUMO

BACKGROUND: The optimal management of blunt thoracic aortic injury (BTAI) remains controversial, with experienced centers offering therapy ranging from medical management to TEVAR. We investigated the utility of a machine learning (ML) algorithm to develop a prognostic model of risk factors on mortality in patients with BTAI. METHODS: The Aortic Trauma Foundation registry was utilized to examine demographics, injury characteristics, management and outcomes of patients with BTAI. A STREAMLINE (A Simple, Transparent, End-To-End Automated Machine Learning Pipeline Facilitating Data Analysis and Algorithm Comparison) model as well as logistic regression (LR) analysis with imputation using chained equations was developed and compared. RESULTS: From a total of 1018 patients in the registry, 702 patients were included in the final analysis. Of the 258 (37%) patients who were medically managed, 44 (17%) died during admission, 14 (5.4%) of which were aortic related deaths. Four hundred forty-four (63%) patients underwent TEVAR and 343 of which underwent TEVAR within 24 hours of admission. Among TEVAR patients, 39 (8.8%) patients died and 7 (1.6%) had aortic related deaths ( Table 1 ). Comparison of the STREAMLINE and LR model showed no significant difference in ROC curves and high AUCs of 0.869 (95% confidence interval, 0.813-0.925) and 0.840 (95% confidence interval, 0.779-0.900) respectively in predicting in-hospital mortality. Unexpectedly, however, the variables prioritized in each model differed between models. The top 3 variables identified from the LR model were similar to that from existing literature. The STREAMLINE model, however, prioritized location of the injury along the lesser curve, age and aortic injury grade. CONCLUSION: Machine learning provides insight on prioritization of variables not typically identified in standard multivariable logistic regression. Further investigation and validation in other aortic injury cohorts are needed to delineate the utility of ML models. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level III.

RESUMO

OBJECTIVE: We conducted a comprehensive evaluation of features associated with stroke records. METHODS: We screened the dietary nutrients, blood biomarkers, and clinical information from the National Health and Nutrition Examination Survey (NHANES) 2015-16 database to assess a self-reported history of all strokes (136 strokes, n = 4381). We computed feature importance, built machine learning (ML) models, developed a nomogram, and validated the nomogram on NHANES 2007-08, 2017-18, and the baseline UK Biobank. We calculated the odds ratios with/without adjusting sampling weights (OR/ORw). RESULTS: The clinical features have the best predictive power compared to dietary nutrients and blood biomarkers, with 22.8% increased average area under the receiver operating characteristic curves (AUROC) in ML models. We further modeled with ten most important clinical features without compromising the predictive performance. The key features positively associated with stroke include age, cigarette smoking, tobacco smoking, Caucasian or African American race, hypertension, diabetes mellitus, asthma history; the negatively associated feature is the family income. The nomogram based on these key features achieved good performances (AUROC between 0.753 and 0.822) on the test set, the NHANES 2007-08, 2017-18, and the UK Biobank. Key features from the nomogram model include age (OR = 1.05, ORw = 1.06), Caucasian/African American (OR = 2.68, ORw = 2.67), diabetes mellitus (OR = 2.30, ORw = 1.99), asthma (OR = 2.10, ORw = 2.41), hypertension (OR = 1.86, ORw = 2.10), and income (OR = 0.83, ORw = 0.81). CONCLUSIONS: We identified clinical key features and built predictive models for assessing stroke records with high performance. A nomogram consisting of questionnaire-based variables would help identify stroke survivors and evaluate the potential risk of stroke.

RESUMO

OBJECTIVES: Vascular surgery training programs face multiple pressures, including attracting and retaining trainees. Current knowledge of trainees' views with respect to diversity and equity in vascular training programs is limited. We sought to understand United States vascular surgery trainees' perceptions and expectations regarding diversity, equity, and inclusion (DEI). METHODS: The Association of Program Directors in Vascular Surgery designed and administered the Annual Training Survey to specifically address DEI and administered it to all trainees (Integrated Residents/Fellows; n = 637) at 122 institutions in August 2020. RESULTS: Of the 637 vascular trainees, 227 (35%) responded. The respondents included 115 male and 62 female trainees, with 50 not disclosing or not answering the question. The majority of respondents (96.9%) believed their programs incorporated a diverse background of trainees. Of the trainees, 89.8% felt that the faculty were similarly comprised of a diverse background. The majority of respondents (63.6%) felt that their training program was both more diverse and focused on inclusion compared with other training programs at their institution. However, 20% of respondents had experienced discrimination. Seventy-three percent (n = 143) of trainees felt empowered to disagree or engage in a discussion should they observe a faculty member make a disparaging remark about a patient's background/race/gender, although 27% (n = 35) trainees expressed fear of retaliation as a reason to not engage. Trainees view their program director (82.6%), faculty mentor (60.9%), and Graduate Medical Education office (52.7%) as potential resources for support. Overall, 83.7% (n = 160) of trainees believe that their program has been open to discussion of race relations within the medical community. CONCLUSIONS: Trainees are committed to multifaceted diversity and inclusion. The perception of trainees regarding DEI issues within vascular surgery training programs appears to be positive; however, trainees did describe discrimination and gender biases in their institutions. This data has the potential to improve institutional education of faculty and trainees about the multidimensional levels of diversity and increased awareness and incorporation of this philosophy can assist in the recruitment of diverse vascular surgeons.

RESUMO

OBJECTIVE: In this multi-institutional series, we aimed to determine the incidence, risk factors, and long-term outcomes of graft infection in patients post-femoropopliteal bypass. METHODS: A multi-institutional database was retrospectively queried for all femoropopliteal bypass procedures from 1995 through 2020. Cumulative incidence function estimated the long-term rate of bypass graft infection (BGI), and the Fine-Gray model was used to determine independent risk factors for BGI to account for death as a competing risk. RESULTS: Over the 25-year period, 1315 femoral popliteal bypasses were identified with a median follow-up of 2.89 years (interquartile range, 0.75-6.55 years). BGI was diagnosed in 34 patients (2.6%). BGI occurred between 9 days and 11.2 years postoperatively, with a median of 109 days. Estimated 1- and 5-year incidence of BGI was 2.1% (95% confidence interval [CI], 1.4%-3.1%) and 2.8% (95% CI, 1.9%-3.9%), respectively. Medical comorbidities, indications for bypass, and popliteal bypass targets (above- vs below-knee) were similar between patients with BGI and all patients (P = not significant for each). Patients with BGI were more frequently complicated by postoperative hematoma (14.7% vs 3.7%), superficial wound infection (38.2% vs 19.2%), lymphocele/lymphorrhea (8.8% vs 2.1%), and 30-day readmission rates (47.1% vs 21.3%) (P < .05 for each). Most commonly isolated pathogens were Staphylococcus aureus (n = 19; 55.9%) and polymicrobial cultures (n = 5; 14.7%). Reoperation for BGI involved incision and drainage (n = 7; 20.6%), graft excision without reconstruction (n = 12; 35.3%), graft excision with in-line reconstruction (n = 11; 32.4%), and graft excision with extra-anatomic reconstruction (n = 2; 5.9%). Nine patients with BGI (26.5%) ultimately required major amputation. Prosthetic bypass (subdistribution hazard ratio [SHR], 3.73; 95% CI, 1.64-8.51; P = .002), postoperative hematoma (SHR, 3.44; 95% CI, 1.23-9.61; P = .018), and 30-day readmission (SHR, 2.75; 95% CI, 1.27-5.44; P = .010) were independently associated with BGI. One-year amputation-free survival was 50% (95% CI, 31.9%-65.7%) after BGI. CONCLUSIONS: BGI is a rare complication of femoral-popliteal bypass with significant morbidity. Graft infection is associated with the use of prosthetic grafts, postoperative hematoma, and unplanned hospital readmission. Mitigation of these risk factors may decrease the risk of this dreaded complication.

RESUMO

OBJECTIVE: Recent initiatives have emphasized the importance of diversity, equity, and inclusion in academic surgery. Racial/ethnic disparities remain prevalent throughout surgical training, and the "diversity pipeline" in resident recruitment and retention remains poorly defined. METHODS: Data was retrospectively collected using two separate datasets. The Association of American Medical Colleges database was used to obtain demographic data on US medical school graduates. The US Graduate Medical Education annual report was used to obtain demographic data on surgical residents. Wilcoxon signed-rank test was used to compare racial/ethnic distribution within surgical residency programs with graduating medical students. Linear regression analysis was performed to analyze population trends over time. RESULTS: The study population included 184,690 surgical residents from 2011 to 2020. Nine resident cohorts were created according to surgical specialty - general surgery, neurosurgery, ophthalmology, orthopedic surgery, otolaryngology, plastic surgery, cardiothoracic surgery, urology, and vascular surgery. Among surgical programs, White residents were overrepresented in 8 of 9 specialties compared to the concurrent graduating medical student class for all years (p < 0.01 each, no difference in ophthalmology). Black residents were underrepresented in 8 of 9 specialties (p < 0.01 each, no difference in general surgery). Asian representation was mixed among specialties (4 overrepresented, 1 equal, 4 underrepresented), as was Hispanic representation (5 overrepresented, 4 equal) (p < 0.01 each). CONCLUSIONS: These data suggest that racial/ethnic disparities are inherent to the process of recruitment and retention of surgical residents. Efforts to improve the "diversity pipeline" should focus on mentorship and development of minority medical students and creating an equitable learning environment.

RESUMO

OBJECTIVE: Primary leiomyosarcoma of the inferior vena cava (IVC) is best managed with surgical resection when technically feasible. However, consensus is lacking regarding the best choice of conduit and reconstruction technique. The aim of the present multicenter study was to perform a comprehensive assessment through the VLFDC (Vascular Low Frequency Disease Consortium) to determine the most effective method for caval reconstruction after resection of primary leiomyosarcoma of the IVC. METHODS: A multicenter, standardized database review of patients who had undergone surgical resection and reconstruction of the IVC for primary leiomyosarcoma from 2007 to 2017 was performed. The demographics, periprocedural details, and postoperative outcomes were analyzed. RESULTS: A total of 92 patients (60 women and 32 men), with a mean age of 60.1 years (range, 30-88 years) were treated. Metastatic disease was present in 22%. The tumor location was below the renal veins in 49 (53%), between the renal and hepatic veins in 52 (57%), and above the hepatic veins in 13 patients (14%). The conduits used for reconstruction included ringed polytetrafluoroethylene (PTFE; n = 80), nonringed PTFE (n = 1), Dacron (n = 1), autogenous vein (n = 1), bovine pericardium (n = 4), and cryopreserved tissue (n = 5). Complete R0 resection was accomplished in 73 patients (79%). In-hospital mortality was 2%, with a median length of stay of 8 days. The primary patency of PTFE reconstructed IVCs was 97% and 92% at 1 and 5 years, respectively, compared with 73% at 1 and 5 years for the non-PTFE reconstructed IVCs. The overall 1-, 3-, and 5-year survival for the entire cohort were 94%, 86%, and 65%, respectively CONCLUSIONS: The findings from our multi-institutional study have demonstrated that complete en bloc resection of IVC leiomyosarcoma with vascular surgical reconstruction in selected patients results in low perioperative mortality and is associated with excellent long-term patency. A ringed PTFE graft was the most commonly used conduit for caval reconstruction, yielding excellent long-term primary patency.

RESUMO

OBJECTIVE: To determine if premature menopause and early menarche are associated with increased risk of AAA, and to explore potential effect modification by smoking history. SUMMARY OF BACKGROUND DATA: Despite worse outcomes for women with AAA, no studies have prospectively examined sex-specific risk factors, such as premature menopause and early menarche, with risk of AAA in a large, ethnically diverse cohort of women. METHODS: This was a post-hoc analysis of Women's Health Initiative participants who were beneficiaries of Medicare Parts A&B fee-for-service. AAA cases and interventions were identified from claims data. Follow-up period included Medicare coverage until death, end of follow-up or end of coverage inclusive of 2017. RESULTS: Of 101,119 participants included in the analysis, the mean age was 63 years and median follow-up was 11.3 years. Just under 10,000 (9.4%) women experienced premature menopause and 22,240 (22%) experienced early men-arche. Women with premature menopause were more likely to be overweight, Black, have >20 pack years of smoking, history of cardiovascular disease, hypertension, and early menarche. During 1,091,840 person-years of follow-up, 1125 women were diagnosed with AAA, 134 had premature menopause (11.9%), 93 underwent surgical intervention and 45 (48%) required intervention for ruptured AAA. Premature menopause was associated with increased risk of AAA [hazard ratio 1.37 (1.14, 1.66)], but the association was no longer significant after multivariable adjustment for demographics and cardiovascular disease risk factors. Amongst women with ≥20 pack year smoking history (n = 19,286), 2148 (11.1%) had premature menopause, which was associated with greater risk of AAA in all models [hazard ratio 1.63 (1.24, 2.23)]. Early menarche was not associated with increased risk of AAA. CONCLUSIONS: This study finds that premature menopause may be an important risk factor for AAA in women with significant smoking history. There was no significant association between premature menopause and risk of AAA amongst women who have never smoked. These results suggest an opportunity to develop strategies for better screening, risk reduction and stratification, and outcome improvement in the comprehensive vascular care of women.

RESUMO

OBJECTIVES: Acute mesenteric ischemia (AMI) is a life-threatening condition associated with dismal outcomes. This study sought to evaluate the evolution of presentation, treatment, and outcomes of AMI over the past two decades. METHODS: AMI patients presenting at a single institution were reviewed (1993-2016). Venous thrombosis patients were excluded. Primary outcome was 30-day mortality. Patients were stratified by etiology and diagnosis date (before 2004 versus 2004 and later). Ordered logistic regression was performed for longitudinal temporal analysis. RESULTS: 303 patients were identified. AMI mechanisms included: embolic (49%), thrombotic (29%), and non-occlusive (NOMI) (22%). The majority were women (55%), 50% had atrial fibrillation, and 23% were on anticoagulation (AC) therapy. Mean age was 72±13 years. 345 procedures were performed in 242 patients: 321 open and 24 hybrid/endovascular. Among the 189 embolic/thrombotic patients who were managed operatively, 45% (n=85) underwent mesenteric revascularization while 39 (21%) had findings of non-survivable bowel necrosis (NSBN). Among the 104 patients who did not undergo revascularization, 64 (62%) died within 30-days compared to 36 out of 85 (42%) patients who were revascularized (P=0.01). 30-day mortality was 61% and stable over time (P=0.91); when stratified by AMI etiology, the thrombotic cohort had worse survival than embolic and NOMI patients (P=0.04). Since 2000, there was a significant decrease in the percentage of embolic AMI events (P=0.04). The percentage of patients who underwent operative management decreased also over time (P=0.01, 81% → 61%), which was correlated with an increasing number of patients being made comfort measures only (CMO) prior to surgical intervention (50% → 70%, P=0.02). The majority of patients (55%) were ultimately made CMO during their hospitalization. Predictors of 30-day mortality included a preoperative white blood cell count (WBC) ≥ 25 K/ µL. (OR 3.0, P=0.002) and lactate ≥ 2.3 mmol/L (OR 2.8, P=0.045). NSBN predictors included WBC ≥ 24 K/ µL. (OR 3.4 P=0.03) and lactate ≥ 3.8 mmol/L (OR 3.6, P=0.04). CONCLUSIONS: Despite advances in critical care over the past 25 years, AMI continues to be associated with poor prognosis. The survival benefit observed in patients who undergo revascularization supports an aggressive approach towards early vascular intervention, although this requires further study. The importance of early diagnosis, prognostication and advanced directives is highlighted given the high morbidity, mortality and use of comfort measures associated with AMI.

RESUMO

OBJECTIVE: Venous mesenteric ischemia (VMI) presents with variable severity resulting in a spectrum of outcomes. This study sought to characterize the natural history of VMI and identify drivers of intervention and adverse outcomes. METHODS: All patients who presented to our institution with acute and subacute VMI between 1993 and 2016 were identified. Images were reviewed to determine thrombosis location and charts were reviewed to identify clinical factors and outcomes. Univariate analysis was performed for demographics, comorbidities, and presenting characteristics, with primary outcomes of intervention, readmission, and 30-day mortality. A survival analysis was performed with log-rank difference testing for demographics, comorbidities, and presenting characteristics. RESULTS: We identified 103 patients with acute and subacute VMI. The locations of the thrombosis included the superior mesenteric vein (SMV) (31.1%); SMV and portal vein (35.9%); SMV, portal, and splenic veins (15.5%); and other combinations of portomesenteric veins (17.4%), without correlation between the location and outcomes. Most patients were male (60.6%), 22.3% were actively smoking, and the median Charlson comorbidity score was 4 (interquartile range, 2-7). The mean patient age was 61.3 years. More than one-half had a known hypercoagulability (52.4%), 22.3% had prior bowel resection, and 8.7% had prior mesenteric venous intervention, including transjugular intrahepatic portosystemic shunt procedures. Thirty-five patients underwent 83 procedures during their hospitalization, and 23 patients underwent surgical intervention specifically. Prior mesenteric venous procedure, abdominal tenderness, and lactatemia of more than 1.5 mmol/L were associated with an increased need for surgical intervention (P < .05). Patients with leukocytosis of greater than 10K/µL had increased surgical intervention (P = .10), although without statistical significance. However, symptoms for less than 2 weeks (P < .05) were associated with decreased surgical intervention. The 30-day mortality was low in this cohort (6.8%), but was increased in patients requiring intervention (11.4%). For those undergoing procedures, a shorter time to intervention was associated with an improved 30-day mortality (8.7% for procedures on hospital days 0-1 vs 16.7% for hospital day 2 or later; P = .01). Abdominal tenderness and lactatemia were associated with increased 30-day mortality (6.8% vs 3.6% [P < .01] and 16.0% vs 3.8% [P = .03], respectively). A Kaplan-Meier survival analysis revealed a median survival of 7.1 years, with a 1-year survival rate of 74.9%, a 3-year survival rate of 67.1%, and a 5-year survival rate of 57.9%. Negative predictors of survival included a higher Charlson comorbidity index (hazard ratio, 3.7; P < .01) and malignancy (hazard ratio, 3.1; P < .01). CONCLUSIONS: The 30-day mortality of VMT is low, but more than one-third of patients required an intervention beyond anticoagulation. Comorbidity, a prior mesenteric vessel or intestinal operation, and presentation with tenderness or relevant laboratory abnormalities portend worse outcomes. Early intervention is associated with improved outcomes.

RESUMO

OBJECTIVE: Thoracic endovascular aortic repair (TEVAR) results have been studied in short-term time frames. This study aimed to evaluate midterm and long-term outcomes of TEVAR, emphasizing postoperative aortic remodeling and need for reintervention. METHODS: This is an institutional retrospective review of TEVAR for isolated descending thoracic aortic aneurysms. Data were collected from 2004 to 2018. Primary outcomes studied included aneurysm sac remodeling, freedom from reintervention, and all-cause mortality. Other outcomes studied include endoleak rates, neurologic complication rates, and any overall postoperative complication rates. RESULTS: During the study period, 219 patients underwent TEVAR for descending thoracic aortic aneurysms. The median effect of TEVAR on sac diameter was a 0.7-cm decrease in size (interquartile range, -1.4 to 0.0 cm). During the study period, 80% (n = 147) of patients experienced aneurysm sac regression or stability. Perioperative neurologic complications occurred in 16% (n = 34) of patients. Significant predictors of sac growth were endoleak (odds ratio [OR], 65; P < .001), preoperative carotid-subclavian bypass (OR, 8; P = .003), and graft oversizing <20% (OR, 15; P = .046). Every 1-mm increase in aortic diameter at the proximal TEVAR landing zone led to an increased odds of endoleak (OR, 2; P = .049). Access complications (OR, 8) and subclavian artery coverage (OR, 6) significantly increased the odds of reintervention, whereas every percentage of graft oversizing protected against reintervention (OR, 0.005). Life-table analysis revealed an overall survival of 78% (71%-83%) at median follow-up. At 3 years, survival was 88% (80%-93%) for those with aneurysm sac stability or regression, whereas it was 70% (49%-84%) for those with aneurysm sac growth (P = .0402). Cox proportional hazards model showed that the only protective factor for mortality was percentage oversizing, with every 1% of oversizing having a hazard ratio (HR) of <.001 (P = .032). This was counterbalanced by the fact that patients with graft oversizing >30% had an increased odds of mortality with HR >10 (P = .049). Other significant factors that increased the odds of mortality included endoleak (HR, 3.6; P = .033), diabetes (HR, 4.1; P = .048), age (every 1-year increase in age; HR, 1.2; P = .002), year of surgery (every year subsequent to 2004; HR, 1.3; P = .012), and peripheral artery disease (HR, 5.2; P = .041). CONCLUSIONS: The majority of patients (80%) experience sac stability or regression after TEVAR, which offers a clear survival advantage. Endoleaks are predictive of sac growth, conferring increased mortality. Rigorous surveillance is necessary to prevent future aortic events through reintervention.

RESUMO

OBJECTIVE: Few studies have prospectively examined the associations of lipoprotein(a) [Lp(a)] levels with the risk of abdominal aortic aneurysm (AAA), especially in women. Accounting for commonly recognized risk factors, we investigated the baseline Lp(a) levels and the risk of AAA among postmenopausal women participating in the ongoing national Women's Health Initiative. METHODS: Women's Health Initiative participants with baseline Lp(a) levels available who were beneficiaries of Medicare parts A and B fee-for-service at study enrollment or who had aged into Medicare at any point were included. Participants with missing covariate data or known AAA at baseline were excluded. Thoracic aneurysms were excluded owing to the different pathophysiology. The AAA cases and interventions were identified using the International Classification of Diseases, 9th and 10th revision, codes and Current Procedural Terminology codes from claims data. Hazard ratios were computed using Cox proportional hazard models according to the quintiles of Lp(a). RESULTS: The mean age of the 6615 participants included in the analysis was 65.3 years. Of the 6615 participants, 66.6% were non-Hispanic white, 18.9% were black, 7% were Hispanic and 4.7% were Asian/Pacific Islander. Compared with the participants in the lowest Lp(a) quintile, those in higher quintiles were more likely to be overweight, black, and former or current smokers, to have hypertension, hyperlipidemia, and a history of cardiovascular disease, and to use menopausal hormone therapy and statins. During 65,476 person-years of follow-up, with a median of 10.4 years, 415 women had been diagnosed with an AAA and 36 had required intervention. More than one half had required intervention for a ruptured AAA. We failed to find a statistically significant association between Lp(a) levels and incident AAA. Additional sensitivity analyses stratified by race, with exclusion of statin users and alternative categorizations of Lp(a) using log-transformed levels, tertiles, and a cutoff of >50 mg/dL, were conducted, which did not reveal any significant associations. CONCLUSIONS: We found no statistically significant association between Lp(a) levels and the risk of AAA in a large and well-phenotyped sample of postmenopausal women. Women with high Lp(a) levels were more likely to be overweight, black, and former or current smokers, and to have hypertension, hyperlipidemia, and a history of cardiovascular disease, or to use hormone therapy and statins compared with those with lower Lp(a) levels. These findings differ from previous prospective, case-control, and meta-analysis studies that had supported a significant relationship between higher Lp(a) levels and an increased risk of AAA. Differences in the association could have resulted from study limitations or sex differences.

RESUMO

INTRODUCTION: The gold-standard for management of combined common femoral artery (CFA) and superficial femoral artery (SFA) atherosclerotic occlusive disease has traditionally been open femoral endarterectomy and femoral-popliteal bypass. Hybrid approaches involving an open and endovascular component are increasingly common. The aim of this study was to compare perioperative outcomes in patients who underwent an open versus hybrid revascularization. METHODS: NSQIP data, years 2012-2017, were queried for patients who underwent nonemergent CFA endarterectomy with either SFA transluminal intervention or bypass. The primary outcome of interest was a composite of cardiovascular, pulmonary, and renal complications (systemic) and mortality. Two propensity-weight adjusted analyses were performed: 1) comparing hybrid and prosthetic bypass 2) comparing hybrid and vein bypass. RESULTS: There were 4,478 patients included (1,537 hybrid, 1,408 prosthetic, 1,533 vein); 64.8% were men, and the mean age was 67.8 ± 9.7 years; 29.9% had claudication, 38.8% had tissue loss, and 31.3 were unspecified. In the propensity-weighted analysis comparing hybrid to prosthetic bypass, there was no difference in systemic complications (OR = 1.29 for prosthetic vs. hybrid; 95% CI: 0.95-1.76; P = 0.107) or mortality (OR = 1.54; 95% CI: 0.71-3.33; P = 0.275). Prosthetic bypass was associated with more deep surgical-site infections (OR = 2.02; 95% CI: 1.19-3.45; P = 0.010), postoperative sepsis (OR = 2.07; 95% CI: 1.13-3.76; P = 0.018), unplanned 30-day readmission (OR = 1.28; 95% CI: 1.04-1.58; P = 0.021), and the composite of any complication (OR = 1.38; 95% CI: 1.18-1.61; P < 0.001). In the propensity-weighted analysis comparing hybrid to vein bypass, there was no difference in systemic complications (OR = 1.10 for vein vs. hybrid; 95% CI: 0.81-1.49; P = 0.552) or mortality (OR = 0.91; 95% CI: 0.42-2.00; P = 0.819). Vein bypass was associated with more superficial surgical-site infections (OR = 1.45; 95% CI: 1.04-2.02; P = 0.028), and the composite of any complication (OR = 1.32; 95% CI: 1.13-1.54; P = 0.001). Overall mortality was significantly higher patients with systemic complications (13.9% vs 0.1%; P < 0.001). Systemic complications were less common in patients with claudication undergoing hybrid revascularization than vein or prosthetic bypass. CONCLUSIONS: Claudicants undergoing bypass experienced more systemic complications than those undergoing hybrid procedures, but there appears to be no increased risk of systemic complications or mortality with open reconstruction when compared to hybrid procedures for other indications. Other complications, such as infection, postoperative transfusion, and readmission, were more common in the bypass groups.

RESUMO

OBJECTIVE: During the COVID-19 pandemic, central venous access line teams were implemented at many hospitals throughout the world to provide access for critically ill patients. The objective of this study was to describe the structure, practice patterns, and outcomes of these vascular access teams during the COVID-19 pandemic. METHODS: We conducted a cross-sectional, self-reported study of central venous access line teams in hospitals afflicted with the COVID-19 pandemic. To participate in the study, hospitals were required to meet one of the following criteria: development of a formal plan for a central venous access line team during the pandemic; implementation of a central venous access line team during the pandemic; placement of central venous access by a designated practice group during the pandemic as part of routine clinical practice; or management of an iatrogenic complication related to central venous access in a patient with COVID-19. RESULTS: Participants from 60 hospitals in 13 countries contributed data to the study. Central venous line teams were most commonly composed of vascular surgery and general surgery attending physicians and trainees. Twenty sites had 2657 lines placed by their central venous access line team or designated practice group. During that time, there were 11 (0.4%) iatrogenic complications associated with central venous access procedures performed by the line team or group at those 20 sites. Triple lumen catheters, Cordis (Santa Clara, Calif) catheters, and nontunneled hemodialysis catheters were the most common types of central venous lines placed by the teams. Eight (14%) sites reported experience in placing central venous lines in prone, ventilated patients with COVID-19. A dedicated line cart was used by 35 (59%) of the hospitals. Less than 50% (24 [41%]) of the participating sites reported managing thrombosed central lines in COVID-19 patients. Twenty-three of the sites managed 48 iatrogenic complications in patients with COVID-19 (including complications caused by providers outside of the line team or designated practice group). CONCLUSIONS: Implementation of a dedicated central venous access line team during a pandemic or other health care crisis is a way by which physicians trained in central venous access can contribute their expertise to a stressed health care system. A line team composed of physicians with vascular skill sets provides relief to resource-constrained intensive care unit, ward, and emergency medicine teams with a low rate of iatrogenic complications relative to historical reports. We recommend that a plan for central venous access line team implementation be in place for future health care crises.

RESUMO

OBJECTIVE: Carotid endarterectomy (CEA) is the most commonly performed surgical procedure to reduce the risk of stroke. The operation may be performed under general anesthesia (GA) or regional anesthesia (RA). We used a national database to determine how postoperative outcomes were influenced by gender and type of anesthesia used. METHODS: All patients who underwent CEA between 2005 and 2011 were identified from the American College of Surgeons National Surgical Quality Improvement Program database (N = 41,442). Incidence of stroke and myocardial infarction (MI) within 30 days as well as other postoperative complications, operative time, and hospital length of stay were examined in groups separated by gender and anesthesia type. Multivariable logistic regression with effect modification was used to determine significant risk-adjusted differences between genders and type of anesthesia to assess outcomes after CEA. RESULTS: The male-to-female ratio among CEA cases performed was approximately 3:2. Most cases were performed under GA (85% male patients, 86% female patients). Adjusted multivariable analysis showed no statistical difference in rates of MI and stroke based on gender or type of anesthesia used. There were, however, higher 30-day postoperative local complications and MI (both P < .05) in those who had GA vs RA regardless of gender before adjustment. Total operative time was decreased (mean difference, -8.15 minutes; 95% confidence interval, -10.09 to -6.21; P < .001) and length of stay was increased (mean difference, 0.34 day; 95% confidence interval, 0.14-0.54; P < .02) in women, with statistical significance, whether RA or GA was used. CONCLUSIONS: On adjusted multivariate analysis, there is no statistically significant difference in postoperative incidence of MI or stroke between men and women undergoing CEA. Use of RA vs GA did not affect this finding. Furthermore, there was no correlation between gender and the type of anesthesia chosen. Women, however, experienced decreased operative times and increased length of stay regardless of anesthesia type.

RESUMO

Vascular injury during anterior lumbar interbody fusion (ALIF) is a well-documented occurrence. Most vascular injuries continue to be managed with direct open repair. We report the outcome of a 61-year-old woman who experienced inferior vena cava and left common iliac vein injury during a difficult exposure for multilevel ALIF. The distal cava and common iliac vein were repaired with a Gore Excluder cuff and limb. The endovascular repair permitted control of the injury without more morbid maneuvers such as iliac artery transection. Thus endovascular repair of intraoperative caval injury is a valuable option in emergent situations with low morbidity and good durability.

RESUMO

The exponential rise in inferior vena cava (IVC) filter placement is associated with increased complications both during implantation and retrieval. In this report, a 64-year-old man was transferred from an outside hospital with cardiac tamponade secondary to a snare eroding into the right atrium. This complication occurred after attempted suprarenal IVC filter removal. The filter, entangled with the snare, was retrieved by a hybrid technique of mobilizing the liver to expose the suprarenal IVC, followed by using a snare and sheath to compress and extrude the filter. This is the first reported hybrid retrieval of a suprarenal IVC filter.

RESUMO

Dermatologists encounter a wide range of cutaneous vascular lesions, including infantile hemangiomas, port-wine stain birthmarks, arteriovenous malformations, venous malformations, Kaposi sarcomas, angiosarcomas, and angiofibromas. Current treatment modalities to reduce these lesions include topical and/or intralesional steroids, laser therapy, surgical resection, and endovascular therapy. However, each method has limitations owing to recurrence, comorbidities, toxicity, or lesion location. Photodynamic therapy, antiangiogenic therapy, and evolving methods of sclerotherapy are promising areas of development that may mitigate limitations of current treatments and offer exciting options for patients and their physicians.
