RESUMEN
Arterial thoracic outlet syndrome (TOS) is a condition in which anatomic abnormalities in the thoracic outlet cause compression of the subclavian or, less commonly, axillary artery. Patients are usually younger and typically have an anatomic abnormality causing the compression. The condition usually goes undiagnosed until patients present with signs of acute or chronic hand or arm ischemia. Workup of this condition includes a thorough history and physical examination; chest x-ray to identify potential anatomic abnormalities; and arterial imaging, such as computed tomographic angiography or duplex to identify arterial abnormalities. Patients will usually require operative intervention, given their symptomatic presentation. Intervention should always include decompression of the thoracic outlet with at least a first-rib resection and any other structures causing external compression. If the artery is identified to have intimal damage, mural thrombus, or is aneurysmal, then arterial reconstruction is warranted. Stenting should be avoided due to external compression. In patients with symptoms of embolization, a combination of embolectomy, lytic catheter placement, and/or therapeutic anticoagulation should be done. Typically, patients have excellent outcomes, with resolution of symptoms and high patency of the bypass graft, although patients with distal embolization may require finger amputation.

OBJECTIVE: The purpose of this study was to create a risk score for the event of mortality within 3 years of complex fenestrated visceral segment endovascular aortic repair utilizing variables existing at the time of preoperative presentation. METHODS: After exclusions, 1916 patients were identified in the Vascular Quality Initiative who were included in the analysis. The first step in development of the risk score was univariable analysis for the primary outcome of mortality within 3 years of surgery. χ2 analysis was performed for categorical variables, and comparison of means with independent Student t-test was performed for ordinal variables. Variables that achieved a univariable P value less than 0.1 were then placed into Cox regression multivariable time dependent analysis for the development of mortality within 3 years. Variables that achieved a multivariable significance of less than 0.1 were utilized for the risk score, with point weighting based on the beta-coefficient. Variables with a beta coefficient of 0.25 to 0.49 were assigned 1 point, 0.5 to 0.74 2 points, 0.75 to 0.99 3 points, and 1.0 to 1.25 4 points. A cumulative score for each patient was then summed, the percentage of patients at each score experiencing mortality within 3 weeks was then calculated, and a comparison of score outcomes was conducted with binary logistic regression. Area under the curve analysis was performed. RESULTS: The primary outcome of mortality within 3 years of surgery occurred in 12.8% of patients (245/1916). The mean age for the study population was 73.35 years (standard deviation [SD], 8.26 years). The mean maximal abdominal aortic aneurysm (AAA) diameter was 60.43 mm (SD, 10.52 mm). The mean number of visceral vessels stented was 3.3 (SD, 0.76). Variables present at the time of surgery that were included in the risk score were: hemodialysis (3 points); age >87, chronic obstructive pulmonary disease, hypertension, AAA diameter >77 mm (all 2 points); and body mass index <20 kg/m2, female sex, congestive heart failure, active smoking, chronic renal insufficiency, age 80 to 87 years, and AAA diameter 67 to 77 mm (all 1 point). BMI >30 kg/m2 (mean, 34.46 kg/m2) and age <67 years were protective (-1 point). Testing the model resulted in an area under the curve of 0.706. Hosmer and Lemeshow goodness of fit test for logistic regression utilizing the 15 different risk score total groups revealed a model predictive accuracy of 87.3%. Significant escalations in 3-year mortality were noted to occur at scores of 6 and greater. Mean AAA diameter was significantly larger for patients who had higher risk scores (P < .001). CONCLUSIONS: A novel risk score for mortality within 3 years of fenestrated visceral segment aortic endograft has been developed that has excellent accuracy in predicting which patients will survive and derive the strongest benefit from intervention. This facilitates risk-benefit analysis and counseling of patients and families with realistic long-term expectations. This potentially enhances patient-centered decision-making.

BACKGROUND: The optimal stenting approach for traumatic pseudoaneurysms (PSA) of the extracranial internal carotid artery (ICA) remains underinvestigated. We present a case of a traumatic pseudoaneurysm of the extracranial ICA managed with stenting and review of prior published similar cases. METHODS: The systematic review followed PRISMA-S guidelines and included studies that investigated traumatic pseudoaneurysms of the extracranial ICA managed by stent placement. Statistical analysis assessed the association between the type of injury and stent type, dual antiplatelet therapy (DAPT) duration, and clinical presentation, and the association between stent type and DAPT duration. RESULTS: Our search yielded 82 publications with 135 patients with extracranial ICA PSA treated with stenting. The odds of neck hematoma presentation was 12.2 times greater for patients with penetrating rather than blunt injuries (P = 0.000002). Covered stents had 2.02 times higher odds of use for penetrating rather than blunt injuries compared to bare metal stents. (P = 0.0029). Shorter duration DAPT was seen with bare metal stents having 1.25 higher odds of DAPT duration less than one month compared to covered (P = 0.001). CONCLUSIONS: In traumatic extracranial ICA pseudoaneurysms, covered stents are used more commonly for penetrating injuries compared to blunt injuries. Penetrating injuries are more strongly associated with the presentation of a hematoma compared to blunt injuries. Stent type may influence the recommended DAPT duration. Surgeons should consider these findings when selecting stent type and DAPT duration with patients presenting with traumatic extracranial ICA pseudoaneurysm.

Arterial-enteric fistulas occur from a multitude of causes, especially following surgical manipulation of vasculature. The development of an iliac artery-enteric fistula (IEF) occurs rarely in patients with failed pancreatic transplants. IEFs warrant urgent intervention due to the high mortality from hemorrhagic and septic shock. The diagnosis can be delayed by a lack of suspicion, the low sensitivity of diagnostic tests, and the nonspecific signs of fistulas on computed tomography. The management of IEFs is adapted from guidelines for arterial-enteric fistulas of other causes, with little consensus on ideal vascular reconstruction and postoperative antimicrobial management. The outcomes are limited to the short-term results from case reports and case series. We report two cases of IEFs in patients with a history of simultaneous pancreatic kidney transplant. Our patients underwent successful resolution of gastrointestinal bleeding and sepsis, with definitive management of fistula resection and interposition iliac artery bypass. The index of suspicion for IEFs should be high, and they should be considered as a source of anemia or gastrointestinal bleeding of an unknown source in patients with failed pancreatic transplant. Definitive management should be pursued in patients who can tolerate fistula resection, allograft explant, and arterial reconstruction.
RESUMEN
BACKGROUND: The burden and prognostic significance of coronary artery disease (CAD) in adults with peripheral artery disease and chronic limb-threatening ischemia (CLTI) is unknown. METHODS: Temporal trends in prevalence of significant CAD (history of myocardial infarction or coronary revascularizations) in hospitalizations for CLTI were determined using the 2000 to 2018 National Inpatient Sample (NIS) database. A multivariable regression analysis of outcomes was performed based on presence or absence of CAD. RESULTS: Among 13 575 099 hospitalizations for CLTI (41% female, 69% white, mean age 69 years), 23% had concomitant CAD, of which 11% underwent lower extremity arterial revascularization (43.6% endovascular and 56.4% surgical). The prevalence of concomitant CAD with CLTI increased from 15.3% in 2000 to 23.1% in 2018. Furthermore, the frequency of endovascular revascularization in adults with CAD and CLTI increased from 15.1% to 48.3%, while there was a decreasing trend of surgical revascularization, from 84.9% to 51.7%. After multivariate adjustments, CLTI with CAD was associated with increased risk of in-hospital mortality (OR, 1.40; 95% CI, 1.32-1.47; P less than .0001) and bleeding requiring transfusion (OR, 1.10; 95% CI, 1.06-1.12; P less than .0001) compared with patients with CLTI without CAD. As compared with surgical revascularization, endovascular revascularization was associated with lower risk of in-hospital mortality in both patients with CLTI with CAD (OR, 0.69; 95% CI, 0.63-0.76; P less than .001) and CLTI without CAD (OR, 0.71; 95% CI, 0.67-0.76; P less than .001). CONCLUSIONS: Prevalence of CAD has increased in adults presenting with CLTI and is associated with poor outcomes, warranting the need for effective interventions and secondary prevention in this high-risk population.

Sex-based outcome studies have consistently documented worse results for females undergoing care for abdominal aortic aneurysms. This review explores the underlying factors that account for worse outcomes in the females sex. A scoping review of studies reporting sex-based disparities on abdominal aortic aneurysms was performed. The review was conducted in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for scoping reviews. Factors that account for worse outcomes in the females sex were identified, grouped into themes, and analyzed. Key findings of each study are reported and a comprehensive framework of these factors is presented. A total of 35 studies were identified as critical in highlighting sex-based disparities in care of patients with aortic aneurysms. We identified the following 10 interrelated themes in the chain of aneurysm care that account for differential outcomes in females: natural history, risk factors, pathobiology, biomechanics, screening, morphology, device design and adherence to instructions for use, technique, trial enrollment, and social determinants. Factors accounting for worse outcomes in the care of females with aortic aneurysms were identified and described. Some factors are immediately actionable, such as screening criteria, whereas device design improvement will require further research and development. This comprehensive framework of factors affecting care of aneurysms in females should serve as a blueprint to develop education, outreach, and future research efforts to improve outcomes in females.

BACKGROUND: Acute pulmonary embolism (PE) is a heterogeneous disease process with variable presentation and outcomes. The endogenous fibrinolytic system is a complex framework of regulatory pathways that maintains homeostasis by dissolving overabundant thrombi. We sought to investigate phenotypic profiles of the endogenous fibrinolytic system among patients presenting with acute PE and their impact on mortality. METHODS: We enrolled all consecutive patients with acute PE in our institutional Pulmonary Embolism Response Team registry. We collected blood samples at the time of PE diagnosis and analyzed concentrations of plasminogen activator inhibitor 1 (PAI-1), thrombin-activatable fibrinolysis inhibitor (TAFI), and alpha-2-antiplasmin (A2A). We assessed the association of concentration of fibrinolytic inhibitors and 1-year all-cause mortality and various echocardiographic markers of right ventricular (RV) dysfunction. RESULTS: There is significant variability of PAI-1, A2A, and TAFI concentrations across the spectrum of PE risk profiles with high PAI-1, low TAFI, and low A2A (herein referred to as a high-risk biomarker profile) correlating with worse PE severity. High-risk biomarker profile correlated with high-risk echocardiographic features of RV dysfunction, including increased RV/left ventricular (LV) ratio, low tricuspid annular plane systolic excursion, and low right ventricular outflow tract velocity time integral. Higher-risk biomarker profile was able to discriminate and independently identify patients at high risk of all-cause mortality (Group 2 HR 6 95% CI 1.3-27.8, Group 3 HR 12, 95% CI 1.7-86). CONCLUSIONS: Further studies are needed to assess the exact pathophysiological link between fibrinolytic status and poor outcome after acute PE and to ascertain the impact of anti-inhibitors of the fibrinolytic system on response to therapy and outcomes after acute PE.

BACKGROUND: The risk of spinal cord ischemia (SCI) with aortic aneurysm repair can cause significant neurological morbidity. Prevention of SCI is critical. We sought to identify risk factors that predispose to SCI that may guide strategies to mitigate the occurrence of SCI during and following these procedures. METHODS: This study includes all adults who underwent atraumatic, unruptured, thoracic, and suprarenal aortic aneurysm repairs (endovascular or open) at our institution over 11 years (2010-2020). Our database included patient demographics, aneurysm anatomic features, and operative characteristics and an extreme gradient boost (XGB) machine method was used to develop a predictive model for SCI. The model was trained on an 80% randomly stratified cohort of the data and tested on the remaining 20% testing cohort. Shapley values were used to determine the most important predictive factors of SCI and decision trees were used to identify risk factor threshold values and highest risk factor combinations. RESULTS: Information was collected for 174 adult patients undergoing thoracic and suprarenal aortic repair from 2010 to 2020. Fifty eight percent of the patients were male. Ninety seven (55.7%) patients had open aortic repair and 87 (44.3%) had endovascular repair. Twenty seven (15%) of all patients had major complications and were considered to have SCI. The XGB model converged over the training cohort with a testing cohort accuracy of 0.841 [Sensitivity = 75%, Specificity = 68%] and area under the curve of receiver operating characteristic of 0.774. The XGB model identified older age (> 65 years), history of neurologic disease, hyperlipidemia, diabetes, coronary artery disease, heart failure, poor renal function, < 6 months since last aortic repair, chronic anticoagulant use, preoperational anemia (Hemoglobin < 9), thrombocytopenia (platelet < 90,000), coagulopathy (prothrombin time > 15s and activated partial thromboplastin time > 40s), hypotension (mean arterial pressure < 70 mm Hg), longer operations (> 100 min), aneurysms longer than 5 cm, and anatomic location of aneurysm caudal to T-11 as risk factors for SCI in all types of aortic repair. Diabetic and heart failure patients undergoing longer operations (> 100 min) with thrombocytopenia or aneurysms longer than 5 cm were at the highest risk. CONCLUSIONS: The XGB model accurately identified risk factors of SCI with aortic aneurysm repair that may guide patient selection, timing of surgery, and strategies to minimize the risk of SCI.

A 52-year-old man presented with a chronic type A10 aortic dissection with subsequent aneurysmal degeneration of the left common iliac artery measuring up to 4.6 cm. He had previously undergone hemiarch replacement, which was complicated by renal failure. Owing to the presence of the growing aneurysm, he was unable to be listed for renal transplantation. He declined open operative repair. A novel dual true and false lumen stent graft technique using thoracic endografts was performed to successfully exclude the aneurysm. Follow-up imaging demonstrated aneurysm sac regression, with the patient subsequently undergoing renal transplantation.

INTRODUCTION: While there exists copious short-term data regarding renal function following infra-renal endovascular abdominal aortic aneurysm repair (EVAR), long-term analysis is sparse. This is a single institution retrospective review of predictors of renal function decline 5 years after elective EVAR. METHODS: All EVAR between 2007 and 2015 were queried. Patients in whom renal function was documented 5 years postoperatively were included in analysis. Exclusion criteria were ruptured aneurysm, mortality before 56 months, lack of follow-up, ESRD status, and concomitant renal intervention. The primary outcome investigated was a 20% or greater drop in glomerular filtration rate (GFR) 5 years postoperatively. The following variables at the time of surgery were investigated as potential predictors: age, gender, hypertension, hyperlipidemia, diabetes, CAD or prior MI, COPD, prior stroke, baseline eGFR under 60 mL/min/1.73 m2, supra-renal fixation, infra-renal fixation, neck diameter, neck length, and number of contrast CT. RESULTS: 354 EVAR were identified of which 143 met inclusion criteria (211 excluded). Univariate analysis revealed female gender (OR 2.7), hypertension (OR 9.4), baseline renal insufficiency (OR 3.8), larger neck diameter, and supra-renal fixation (OR 2.32) all predictive (P < .05) of GFR drop at 5 years. Multivariate binary logistic regression analysis found female gender (multivariate OR 3.9, P = .023) and baseline renal insufficiency (multivariate OR 3.0, P = .029) as significant predictors of greater than 20% GFR drop at 5 years. Only 2 patients of the 143 progressed to dialysis requirement at 5 years. CONCLUSIONS: Females and patients with baseline renal insufficiency are more vulnerable to significant decline in renal function 5 years following EVAR. Consistent with analogous literature, supra-renal fixation appears moderately deleterious toward renal function with no clinical significance in those with baseline normal renal function. The potential benefit of avoidance of supra-renal fixation in female patients with baseline renal insufficiency is worth further investigation in a more robust multi-center study.

BACKGROUND: Aortic disease requiring open or endovascular repair may result in spinal cord injury in approximately 2%-10% of patients. Cerebrospinal fluid diversion using lumbar drains (LDs) has been validated as a protective measure to mitigate this complication. METHODS: This single-institution retrospective study analyzed the implementation of a standardized protocol and subsequent educational intervention for LDs for aortic vascular procedures over a 4-year period. RESULTS: In 2016-2019, 45 patients had LDs placed for open or endovascular procedures; group 1 included 19 patients with LDs placed before protocol implementation, and group 2 included 26 patients with LDs placed as per the institutional protocol. Demographics and procedural details in both groups were similar. However, there was a significant difference in the number of patients who had emergent versus planned placement of the LD (group 1, 89.5%; group 2, 50%; P < 0.01), volume of cerebrospinal fluid drained (group 1, 453 mL; group 2, 197 mL; P < 0.01), and compliance with 10 mL/hour drainage recommendation (group 1, 68.4%; group 2, 100%; P < 0.01). In group 1, 5 (31.6%) patients experienced neurological complications compared with only 1 (3.8%) in group 2. LD-related complications occurred 3 patients (15.8%) in group 1, whereas none occurred in group 2. Survey results suggested increased health care worker protocol familiarity with educational interventions. CONCLUSIONS: Implementation of an institutional protocol for LDs for open or endovascular procedures is feasible and beneficial. Educational modules improve familiarity among all health care providers, which can improve patient care and complication avoidance.

Inducing false lumen (FL) thrombosis is crucial to achieve aortic remodeling when treating aortic dissection. One method to achieve FL thrombosis is modifying a graft and placing a plug inside it known as the candy-plug (CP) technique. CP stent graft is typically placed at the level of the celiac artery (CA) as noted by the original authors. Here, we present a case where the CP had to be placed distal to the CA but also require placing a bare metal dissection stent in the true lumen to oppose the radial force and expand the true lumen as well as to prevent re-entry tear in the visceral segment in the future.

OBJECTIVE: Fibromuscular dysplasia rarely involves vessels other than the renal and carotid arteries. We present a case of a rare fibromuscular dysplasia involving multiple vascular beds in a young female patient with history of spontaneous coronary artery (SCAD). METHODS: This is a case report with review of the literature using PubMed search for other cases of fibromuscular dysplasia that involves multiple vascular beds and its association with SCAD. The patient agreed to publish her case including her images. RESULTS: Fibromuscular dysplasia involving multiple vascular beds in a young female patient with prior coronary dissection is rarely reported in the literature. CONCLUSION: Fibromuscular dysplasia affecting multiple vascular beds is rare but should be suspected in patients with SCAD, particularly young female patients.

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.
