The aim of this study is to compare how instructions for use (IFU) affected perioperative and intermediate term outcomes for common iliac artery aneurysms (CIAA) treated with the Gore Excluder iliac branch endoprosthesis (IBE).A retrospective analysis was performed of all patients treated at two affiliated academic centers from September 2016 to May 2020. Outcomes were compared between IFU and nonIFU IBE cases. Criteria for nonIFU included: (1) use with a nonGore aortic endoprosthesis (n = 10), (2) isolated IBE (n = 3), and (3) requiring nondedicated covered stents for additional extension into a more suitable landing zone in the ipsilateral internal iliac artery or one of its branches (n = 11). Perioperative and intermediate term data were collected for both groups. The primary end points were free from the major adverse event (MAE) at 30 days and primary effectiveness at 1 year.A total of 51 CIAA (39 patients) were treated with an IBE. Overall, 15 patients were treated under IFU and 24 under nonIFU. The IFU group mean age was older (72 vs. 67 years, P = 0.03), and males (97%) were primarily treated. Comorbidities were similar except nonIFU had more patients with previous endovascular abdominal aortic aneurysm repair on presentation (0 vs. 4 cases, P = 0.04). Procedure (178 vs. 264 min, P = 0.02) and fluoroscopy (52 vs. 74 min, P = 0.04) times were longer in the nonIFU group. Technical success was 100% for both groups, and there was no difference in device related reintervention at 30 days (0 vs. 1, P = 0.44). There was no MAE in either group at 30 days. Intervention for any endoleak was similar between the groups (2 vs. 3, P = 0.94). Percent CIAA sac regression was similar between the groups (19% vs. 18%, P = 0.21). There was no difference for primary effectiveness at 1 year (93% vs. 92%, P = 0.85). There was one death per group at one year not related to an aortic or iliac cause.In properly selected patients with complex anatomy, IBE can be used with nondedicated aortic and internal iliac components with good early term outcomes.

Vascular research questions can be answered using various study designs. Observational studies are used frequently to address a wide range of clinical questions when randomized clinical trials are not feasible or practical. One of the powerful vascular research tools is the cohort study. The cohort study is a reliable observational study design in which individuals who share a common characteristic (a cohort) are followed over time and their outcomes are assessed at various intervals. This review focuses on the essential characteristics, design, implementation, bias, validity, and clinical significance of cohort studies and provides illustrative examples. A cohort study can be either a prospective or a retrospective study, depending on whether the outcome occurred before or after the enrollment of the cohort. Each type has its advantages and disadvantages. Confounding, selection, and information biases can all occur in cohort studies. Applications of the cohort study design include studying the natural history of a disease, describing a condition's frequency, and investigating multiple outcomes simultaneously.

Thoracic aortic aneurysm and dissection are complex diagnoses that require management by multidisciplinary providers using a variety of medical therapies, surgical interventions, and lifestyle modifications. Pharmacological agents, such as β-blockers (atenolol) and angiotensin II type 1 receptor blockers (losartan), have been mainstay treatments for several years, and research from the past decade has continued to evaluate these and other medication classes to further improve patient morbidity and mortality. Combination β- and renin-aldosterone-angiotensin blockade, statins, metformin, antioxidants, and vitamins have been evaluated as therapeutics in both thoracic and abdominal aortic aneurysms, as well as the effects of various antibiotics (ie, fluoroquinolones and tetracyclines) and benefits of lifestyle modifications (eg, diet and exercise) and enhanced patient-centered care and treatment adherence. In addition, as our understanding of the genetic, biochemical, and pathophysiological mechanisms behind these diseases expands, so do potential targets for future therapeutic research (eg, interleukins, matrix metalloproteases, and mast cells). This review incorporates the major meta-analyses, systematic and generalized reviews, and clinical trials published from 2010 through 2021 that focus on these topics in thoracic aortic aneurysms (and abdominal aneurysms when thoracic literature is scarce). Several key ongoing clinical trials, case studies, and in vivo/in vitro studies are also mentioned. Furthermore, we discuss current gaps in the literature and the abundance of clinical evidence for some interventions in abdominal aneurysms with few thoracic correlates, thus indicating a need for investigation of these subjects in the latter.

Pregnancy-associated aortic dissection (AD) is a rare event, with an incidence of 0.0004% per pregnancy. The work of the Aortic Dissection Collaborative identified pregnancy-associated AD as a high-priority topic, despite its rarity. The Pregnancy Working Group, which included physicians and patient stakeholders, performed a systematic literature review of pregnancy-associated AD from 1960 to 2021 and identified 6,333 articles through PubMed, OVID MEDLINE, Cochrane, Embase, CINAHL and Web of Science. The inclusion criterion was AD in pregnant populations and exclusion criteria were case reports, conference abstracts, and languages other than English. Assessment of full-text articles for eligibility after removal of duplicates from all databases yielded 68 articles to be included in the final review. Topics included were timing of AD in pregnancy, type of AD, and management considerations of pregnancy-associated AD. The Pregnancy Working Group identified gaps in knowledge and future areas of research for pregnancy-associated AD, including clinical management, mental health outcomes post AD, reproductive and genetic counseling, and contraception after AD. Future collaborative projects could be a multicenter, international registry for all pregnancy-associated AD to refine the risk factors, best practice and management of AD in pregnancy. In addition, future mixed methodology studies may be useful to explore social, mental, and emotional factors related to pregnancy-associated AD and to determine support groups' effect on anxiety and depression related to these events in the pregnancy and postpartum period.

Telemedicine uses telephone-based or any form of digital communication for remote clinical services. It has been a field of interest for the last century, with broader implementation of telemedicine technologies during the last 25 years. The COVID-19 pandemic was an impetus for the adoption of these technologies globally across all health care services, including patient care, surgical practice, and workflow. As part of the patient engagement work in the Aortic Dissection Collaborative, this topic was identified as an important patient-centered research topic. Telemedicine has been adopted increasingly in vascular surgery; however, there is little evidence on appropriate use of these technologies pertaining to treating patients with aortic dissection or aortopathy in general. This landscape review summarizes the uses of telemedicine applications pre and post pandemic in medicine and vascular surgery, with a particular focus on uses in aortopathy. Using common resource databases, we identified articles related to the history of telemedicine, its current utilization, and application to vascular surgery and/or aortopathy. We briefly review the history of telemedicine and illustrate a range of applications in medicine before the pandemic, along with its rapid uptake globally during the COVID-19 pandemic. The enablers and barriers to using telemedicine are explored, although as a whole there is satisfaction with its integration among patients and providers. To address these, we offer recommendations to address future research as it pertains to telemedicine technologies in aortic dissection.

Although the topics of surgical techniques and medical therapies have been widely studied in aortic dissection (AD), studies examining the short- and long-term impact of this event on mental health are largely lacking. Many of the studies have used the 36-Item Short Form Survey at variable time points after the event. However, AD as medical trauma has a complex impact on a person's identity. Its implications for emotional, mental, social, existential, and self-concept could be explored more robustly. This topic was identified as a topic of interest by the AD Collaborative. The AD Collaborative Mental Health Working Group was formed and performed a landscape review to summarize current literature surrounding quality of life research in those who have experienced AD, identify gaps in knowledge, and to outline future research questions.

Aortic dissection confers high mortality and morbidity rates despite advances in treatment, impacts quality of life, and contributes immense burden to the healthcare system globally. Efforts to prevent aortic dissection through screening and management of modifiable risk factors and early detection of aneurysms should incorporate genomic information, as it is integral to stratifying risk. However, effective integration of genomic-guided risk assessment into clinical practice will require addressing implementation barriers that currently permeate our healthcare systems. The Aortic Dissection Collaborative was established to define aortic dissection research priorities through patient engagement. Using a collaborative patient-centered feedback model, our Genomic Medicine Working Group identified related research priorities that could be investigated by pragmatic interventional studies aimed at aortic dissection prevention, utilization of genomic information to improve patient outcomes, and access to genomic medicine services. Further research is also needed to identify the genomic, lifestyle, and environmental risk factors that contribute to aortic dissection so these data can be incorporated into future comparative effectiveness studies to prevent aortic dissection.

Understanding what matters most to patients can help guide research in a direction that is best situated to provide evidence that is responsive to their core concerns. This can better inform the treatment decision-making process for patients and their physicians. The Aortic Dissection (AD) Collaborative built a collaborative AD research infrastructure involving patients and other stakeholders to facilitate patient-centered outcomes research training, support, and networking among those affected by AD. Two surveys and semi-structured interviews were conducted between January and October 2020 to gather information from people with and at risk for AD and their family members to better understand their experiences and needs. Discussion of survey and interview results were then articulated as seven key topics for future research to meet the needs of the AD community. Working groups were assembled to address each of the key topics. The groups conducted landscape reviews that were focused on providing guidance for future research that directly addresses the needs identified by the AD community. Recommendations for future research generated by the working groups were compiled by the Aortic Dissection Collaborative. From these recommendations, the Aortic Dissection Collaborative advisors and stakeholders identified high-priority research questions. The research questions form the basis for a third survey, disseminated to the Virtual Research Network between November 2021 and February 2022. Final analysis of the survey will identify top ranked research questions and assess willingness to participate. These results will inform the development of future patient-centered outcomes research and comparative effectiveness research proposals.

The purpose of this study was to report our institutional experience with patients with COVID-19 who developed acute limb ischemia during hospitalization and to determine the characteristics and clinical outcomes. Between March 2020 and January 2021, we treated 3 patients who were COVID-19–positive and developed acute limb ischemia after they received thromboprophylaxis. We performed an embolectomy by exposing the popliteal artery below the knee to treat an occlusion of the popliteal and tibial arteries. An infusion of unfractionated heparin was initiated immediately after surgery, maintaining a partial thromboplastin time ratio > 2.5 times the normal value and transferred the patients to the intensive care unit. However, after these patients developed recurrent acute limb ischemia in the same leg, we decided to perform an embolectomy of popliteal and tibial arteries at the ankle and created an arteriovenous fistula (AVF) with tibial veins using polypropylene 7-0. The first patient died from pneumonia after 3 weeks in the intensive care unit; at that time, the foot was viable with triphasic flow in the distal posterior tibial artery and the AVF was patent. The second and third patients are doing well, they can walk without any problems, and the tibial arteries and AFV were patent on duplex ultrasound after 6 months. The AVF allowed part of the flow of tibial arteries to divert into the small veins of the foot that have a low resistance to maintain patency of tibial vessels, despite a hypercoagulable state and extensive thrombotic microangiopathy in patients with COVID-19.

OBJECTIVE: Vascular surgeons treating patients with ruptured abdominal aortic aneurysm must make rapid treatment decisions and sometimes lack immediate access to endovascular devices meeting the anatomic specifications of the patient at hand. We hypothesized that endovascular treatment of ruptured abdominal aortic aneurysm (rEVAR) outside manufacturer instructions-for-use (IFU) guidelines would have similar in-hospital mortality compared to patients treated on-IFU or with an infrarenal clamp during open repair (ruptured open aortic aneurysm repair [rOAR]). METHODS: Vascular Quality Initiative datasets for endovascular and open aortic repair were queried for patients presenting with ruptured infrarenal AAA between 2013–2018. Graft-specific IFU criteria were correlated with case-specific proximal neck dimension data to classify rEVAR cases as on- or off-IFU. Univariate comparisons between the on- and off-IFU groups were performed for demographic, operative and in-hospital outcome variables. To investigate mortality differences between rEVAR and rOAR approaches, coarsened exact matching was used to match patients receiving off-IFU rEVAR with those receiving complex rEVAR (requiring at least one visceral stent or scallop) or rOAR with infrarenal, suprarenal or supraceliac clamps. A multivariable logistic regression was used to identify factors independently associated with in-hospital mortality. RESULTS: 621 patients were treated with rEVAR, with 65% classified as on-IFU and 35% off-IFU. The off-IFU group was more frequently female (25% vs. 18%, P = 0.05) and had larger aneurysms (76 vs. 72 mm, P = 0.01) but otherwise was not statistically different from the on-IFU cohort. In-hospital mortality was significantly higher in patients treated off-IFU vs. on-IFU (22% vs. 14%, P = 0.02). Off-IFU rEVAR was associated with longer operative times (135 min vs. 120 min, P = 0.004) and increased intraoperative blood product utilization (2 units vs. 1 unit, P = 0.002). When off-IFU patients were matched to complex rEVAR and rOAR patients, no baseline differences were found between the groups. Overall in-hospital complications associated with off-IFU were reduced compared to more complex strategies (43% vs. 60–81%, P < 0.001) and in-hospital mortality was significantly lower for off-IFU rEVAR patients compared to the supraceliac clamp group (18% vs. 38%, P = 0.006). However, there was no significantly increased mortality associated with complex rEVAR, infrarenal rOAR or suprarenal rOAR compared to off-IFU rEVAR (all P > 0.05). This finding persisted in a multivariate logistic regression. CONCLUSIONS: Off-IFU rEVAR yields inferior in-hospital survival compared to on-IFU rEVAR but remains associated with reduced in-hospital complications when compared with more complex repair strategies. When compared with matched patients undergoing rOAR with an infrarenal or suprarenal clamp, survival was no different from off-IFU rEVAR. Taken together with the growing available evidence suggesting reduced long-term durability of off-IFU EVAR, these data suggest that a patient’s comorbidity burden should be key in making the decision to pursue off-IFU rEVAR over a more complex repair when proximal neck violations are anticipated preoperatively.

Implicit bias, microaggressions, and macroaggressions have a negative impact on physician and trainee wellness. In this article, we describe how structural racism, misogyny, and other social constructs have shaped the medical landscape. Increasing awareness in medical education, patient care, and research can help to dismantle the effects.

Quality improvement programs and clinical trial research experienced disruption due to the coronavirus disease 2019 (COVID-19) pandemic. Vascular registries showed an immediate impact with significant declines in second-quarter vascular procedure volumes witnessed across Europe and the United States. To better understand the magnitude and impact of the pandemic, organizations and study groups sent grass roots surveys to vascular specialists for needs assessment. Several vascular registries responded quickly by insertion of COVID-19 variables into their data collection forms. More than 80% of clinical trials have been reported delayed or not started due to factors that included loss of enrollment from patient concerns or mandated institutional shutdowns, weighing the risk of trial participation on patient safety. Preliminary data of patients undergoing vascular surgery with active COVID-19 infection show inferior outcomes (morbidity) and increased mortality. Disease-specific vascular surgery study collaboratives about COVID-19 were created for the desire to study the disease in a more focused manner than possible through registry outcomes. This review describes the pandemic effect on multiple VASCUNET registries including Germany (GermanVasc), Sweden (SwedVasc), United Kingdom (UK National Vascular Registry), Australia and New Zealand (bi-national Australasian Vascular Audit), as well as the United States (Society for Vascular Surgery Vascular Quality Initiative). We will highlight the continued collaboration of VASCUNET with the Vascular Quality Initiative in the International Consortium of Vascular Registries as part of the Medical Device Epidemiology Network coordinated registry network. Vascular registries must remain flexible and responsive to new and future real-world problems affecting vascular patients.

Background Symptomatic peripheral artery disease of the lower extremity rarely affects young adults and, when present, typically has a nonatherosclerotic etiology. Anatomical variants have manifested as symptomatic foot ischemia in four cases in the literature. We describe the case of a 17-year-old girl presenting with foot pain upon plantar flexion due to dynamic dorsalis pedis (DP) artery entrapment by fibrous bands and the extensor hallucis brevis (EHB) tendon. Methods The patient was a 17-year-old girl who presented with right foot pain upon plantar flexion, which resolved upon returning to the neutral position. The potential site of compression was identified on MRI where the DP artery ran deep to the EHB tendon near the first and second tarsometatarsal joints. On diagnostic arteriogram, there was notching of the dorsalis pedis over the talus bone. The dorsalis pedis Doppler signal was obliterated upon plantar flexion. A longitudinal incision was made over the artery in the area of compression. The flexor retinaculum was incised. Abnormal fibrous bands were identified, which were lysed anterior to the artery. The EHB tendon was released and transferred distally to the extensor hallucis longus tendon. Results A completion angiogram showed a persistently patent dorsalis pedis artery with plantar flexion. She was discharged one day postoperatively without issues. On follow-up, the patient was ambulatory with complete resolution of her pain. Arterial duplex demonstrated normal velocities through the dorsalis pedis in all positions. Conclusions Symptomatic peripheral artery disease is a rare presentation in young adults and is usually due to nonatherosclerotic pathophysiology. We present a rare case of dorsalis pedis artery entrapment syndrome. Given the mechanical nature of obstruction, surgical correction was an effective treatment.

Introduction: This study investigated whether a novel therapy called ischemic conditioning (IC) improves walking capacity and lower extremity muscle performance in patients with peripheral vascular disease who experience intermittent claudication. Methods: Forty-three patients with claudication were enrolled and received either IC or IC Sham for 2 weeks in this randomized, controlled, double-blinded, prospective study. IC sessions involved five cycles of alternating 5-min inflations of a blood pressure cuff to 225 mm Hg (25 mm Hg for IC Sham) and 5-min deflations, around the thigh of the affected lower extremity. Results: There was no difference in the change in claudication onset time (Δ = 114 ± 212 s IC vs. 104 ± 173 s IC Sham; p = 0.67) or peak walking time (Δ = 42 ± 139 s IC vs. 12 ± 148 s IC Sham; p = 0.35) between the IC and IC Sham groups. At the level of the knee, participants in the IC group performed more work (Δ = 3,029 ± 4,999 J IC vs. 345 ± 2,863 J IC Sham; p = 0.03) and displayed a greater time to muscle fatigue (Δ = 147 ± 221 s IC vs. −27 ± 236 s IC Sham; p = 0.01). Discussion/Conclusion: In patients with claudication, IC improved total work performed and time to fatigue at the knee but did not change walking parameters.

Made available in DSpace on 2021-06-25T12:21:06Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-10-06 Background The COVID-19 pandemic has made a significant impact on all spheres of society. The objective of this study was to examine the impact of COVID-19 on the practices, finances, and social aspects of Brazilian vascular surgeons' lives. Methods This is a descriptive analysis of the responses from Brazilian vascular surgeons to the cross-sectional anonymous Society for Vascular Surgery Wellness Task Force Pandemic Practice, Anxiety, Coping, and Support Survey for Vascular Surgeons disseminated 14-24 April 2020. Survey dissemination in Brazil occurred mainly via the Brazilian Society of Angiology and Vascular Surgery (SBACV) and social media. The survey evaluated the impact of the COVID-19 pandemic on vascular surgeons' lives by assessing COVID-19-related stressors, anxiety using theGeneral Anxiety Disorder (GAD)-7 scale, and coping strategies using the Brief Coping Orientation to Problems Experienced (Brief-COPE) inventory. Results A total of 452 responses were recorded from Brazil, with 335 (74%) respondents completing the entire survey. The majority of respondents were males (N = 301, 67%) and practiced in an urban hospitals. The majority of respondents considered themselves at high risk to be infected with COVID-19 (N = 251, 55.8%), and just over half the respondents noted that they had adequate PPE at their primary hospital (N = 171, 54%). One hundred and nine (35%) surgeons confirmed that their hospitals followed professional surgical society guidelines for prioritizing surgeries during the pandemic. At the time of the survey, only 33 (10%) surgeons stated they have pre-operative testing of patients for COVID-19 available at their hospital. Academic vascular surgeons reported being redeployed more often to help with other non-vascular duties compared to community-based or solo practitioners (43% vs. 30% vs. 21% respectively,P = .01). Severe anxiety due to pandemic-related financial concerns was similar in those surgeons practicing solo compared to those in community- or academic-based/group practice (46% vs. 38% vs. 22%;P = .54). The respondents reported their anxiety levels as mild based on the stressors investigated instead of moderate-severe (54% vs. 46%;P = .04). Social media was utilized heavily during the pandemic, with video gatherings being the most commonly used tool (76%). Self-distraction (60%) and situational acceptance (81%) were the most frequently reported coping mechanisms used among Brazilian vascular surgeons. Conclusion The COVID pandemic has greatly affected healthcare providers around the world. At the time of this survey, Brazilian vascular surgeons are reporting low anxiety levels during this time and are using mostly active coping mechanisms.

Background Surgical training is constantly adapting to better prepare trainees for an evolving landscape of surgical practice. Training in vascular surgery additionally underwent a paradigm shift with the introduction of the integrated training pathway now more than a decade ago. With this study, we sought to characterize the needs and goals of our current vascular surgery trainee population. Methods The Association of Program Directors in Vascular Surgery Issues Committee compiled a survey to assess demographics, current needs, and goals of trainees and to evaluate trainee distress using a validated seven-item Physician Well-Being Index. The survey was distributed electronically to all current vascular surgery trainees and recent graduates in the academic years 2016-2017 and 2017-2018, and responses were recorded anonymously. Results During the 2 years of the survey, the response rate was 30% (n = 367/1196). The respondents were 55% (n = 202) integrated vascular residents and 45% (n = 165) vascular surgery fellows. In each year of the survey, 60% (n = 102/170) and 58% (n = 86/148) of trainees expressed a desire to pursue academics in their careers, whereas 37% (n = 63/174) and 35% (n = 53/152) indicated their program had structured academic development time (2016-2017 and 2017-2018, respectively). Fifty-five percent (n = 96/174) and 52% (n = 79/152) stated that the overall impact of collaborative learners was positive. More than 60% of respondents in both years of the survey indicated experiencing one or more symptoms of distress on a weekly basis. The frequency of distress was associated with older age and with the presence of an advanced degree in both years of the survey. Sex, level of training, presence of collaborative learners, and having protected research time were not associated with frequency of distress in either year of the survey. Conclusions These results highlight an opportunity for programs to further evaluate the needs of their trainees for academic development during vascular surgery training to better accommodate trainees' career goals. Further investigation to identify modifiable risk factors for distress among vascular surgery trainees is warranted.

Aortic dissection (AD) is recognized as a potentially fatal condition and its standard treatment has been surgical intervention for acute type A AD (TAAD) and complicated acute type B AD (TBAD), and medical management for uncomplicated acute type B AD. Due to rapidly evolving device technologies and minimally invasive surgical techniques that have lowered perioperative risk, there are paradigm shifts for the indications and treatment options for both TAAD and TBAD. In this article, we will discuss the current indications and treatment options for TAAD and TBAD by chronicity of the disease, which comprises four categories: acute TAAD, chronic (repaired) TAAD, acute TBAD, and chronic TBAD. We will also discuss the knowledge gaps in the current surgical management strategies and literature evidence. Open surgical intervention remains the reference standard for acute TAAD and chronic TAAD with complications until an endoprosthesis that will suit the complex anatomy of aortic root, ascending aorta, and aortic arch is developed. Thoracic endovascular aortic repair is now the first line for complicated acute and chronic TBADs. However, we need a larger trials to support the safety and durability of the procedures in patients with uncomplicated TBAD. Without additional data, patients are left to choose between existing treatment options, such as open surgical repair and stent-grafting.

The Aortic Dissection (AD) Collaborative was established to evaluate patient-centered research priorities in AD. Education was identified as a topic of interest by the stakeholders. The AD Collaborative Education Working Group evaluated existing educational resources and identified areas amenable to comparative effectiveness research. The most important positive qualities of available AD education resources are ease of use, diversity of representation, accessibility, and organization. The most important negative qualities of these resources are non-patient-centered language, promotional themes, and those with limited applicability and accessibility. Through a series of focus groups, the Working Group identified target audiences for AD education and educational material content and critically assessed and prioritized barriers to effective AD education. Both the target audiences and the barriers include clinicians and patients themselves. The Working Group defined initiatives to overcome barriers, to include a comprehensive, universally agreed on AD resource that is updated in real time and making education accessible to all relevant target audiences. The Working Group then prioritized needs for comparative effectiveness research in AD education and determined that clinician education is the top priority for future efforts. The Working Group determined that assessment and evaluation of specific and appropriate screening strategies is the second most important priority. Finally, the Working Group identified patient education as the third most important priority, specifically determining how patients and their support groups learn best, the ideal strategies for information dissemination, and methods of assessing understanding and satisfaction with the education process.

Aortic dissection (AD) is a life-threatening rare disease that occurs as a spontaneous tear in the wall of the aorta. Survivors of AD go on to have a chronic disease process that requires lifelong follow-up and management. Although the COVID-19 pandemic has strained health systems and impacted practice in the United States, the effects of these impacts on people living with or at risk for AD is not well understood. This mixed methods project examined the experiences of people in the AD community during the COVID-19 pandemic between March and October 2020. Results reveal that the AD community lacked clear guidance on the role aortic health status plays in COVID-19 risk and experienced significant disruptions in aortic healthcare. At the same time, the new expansion in access to medical care with telehealth conferred unforeseen benefits in the form of reduced barriers for access to specialized aortic health care.

Aortic dissection (AD) is a life-changing event that is often accompanied by a loss of normal quality of life. Survivors of AD go on to have a chronic disease that requires lifestyle modification, medical management, and surgical repair of the aorta. Clinical care includes multiple disciplines, health care settings, and often different geographic locations. This qualitative assessment examined the experiences of people with and at risk for AD. The following four themes emerged: "unnecessary drama" at diagnosis, unmet needs for information and support, the burden of self-advocacy and care coordination, and living with unaddressed mental health impacts. Our findings inform recommendations to advance patient-centered care delivery for individuals with and at risk for AD, improving communication of timely and relevant information, and an approach to care that acknowledges the whole person in clinical decision making.

Introduction The main goal of this systematic review is to analyze the outcomes of acute limb ischemia (ALI) in patients suffering from the novel Coronavirus COVID-19 (Sars-Cov-2). Evidence of acquisition A systematic review on MEDLINE and Embase was conducted up to May 15, 2021. All papers were sorted by abstract and full text by two independent authors. Systematic reviews, commentaries, and studies that did not distinguish status of COVID-19 infection were excluded from review. Patient demographics were recorded along with modality of treatment (endovascular and/or surgical). We analyzed 30-day outcomes, including mortality. Primary outcome was to evaluate clinical characteristic of ALI in patients affected by SARS-CoV-2 in term of location of ischemia, treatment options and 30-day outcomes. Evindence synthesis We selected 36 articles with a total of 194 patients. The majority of patients were male (80%) with a median age of 60 years old. The treatment most used was thromboembolectomy (31% of all surgical interventions). A total of 32 patients (19%) were not submitted to revascularization due to critical status. The rate of technical success was low (68%) and mortality rate was high (35%). Conclusions This review confirms that Sars-Cov-2 is associated with a high risk of ALI. Further studies are needed to investigate the association and elucidate potential mechanisms, which may include a hypercoagulable state and hyperactivation of the immune response. Furthermore, management of ALI is not standardized and depends on patient's condition and extension of the thrombosed segment. ALI in COVID-19 patients is associated with high risk of failure of revascularization and perioperative mortality.

Insurance coverage of vascular surgery patients may differ from patients with less chronic surgical pathologies. The goal of this study is to identify trends in insurance status of vascular surgery patients over the last 10 years at a busy academic center.All consecutive patient visits for a vascular procedure from 2006 to 2016 were retrospectively reviewed from a prospectively collected institutional database. Data points included insurance status, procedures performed, and date of admission. The insurance status was categorized as Medicare, Medicaid, and uninsured. Samples were divided between 2006-2009 and 2011-2016 for comparison. Unpaired t-test, chi-squared test, and regression analysis were used to determine significant trends over the study period.From 2006 to 2016, 6,007 vascular surgery procedures were performed. Procedure volume increased significantly from 1,309 to 4,698 between the 2 timeframes (P 0.05), whereas the percentage of Medicaid and Medicare patients trended upward but did not achieve significance. There was a significant decrease in the percentage of uninsured patients between the cohorts (5.65% vs. 2.96%, P 0.05). In 2012, 10.14% of patients were uninsured compared with 2.56% in 2016 (P 0.05).Insurance status affects access to care and subsequent outcomes. In our busy academic center, insurance coverage for vascular surgery has significantly increased over the past decade. The number of Medicaid and Medicare patients has slowly increased, but a significant and continuing decline in uninsured patients was observed. Implementation of the Affordable Care Act during this time period may have played a role in providing coverage for patient needing vascular surgery.

Background The impact of the Coronavirus Disease 19 (COVID-19) pandemic on healthcare workers has been substantial. However, the impact on vascular surgery trainees have not yet been determined. The goals of our study were to gauge the impact of COVID-19 on vascular surgery trainees’ personal and professional life and to assess stressors, coping, and support structures involved in these trainees response to the COVID-19 pandemic. Material and methods This was an anonymous online survey administered in April 12-24, 2020 during the surge phase of the global COVID-19 pandemic. It is a subset analysis of the cross-sectional Society for Vascular Surgery Wellness Committee Pandemic Practice, Anxiety, Coping and Support Survey. The cohort surveyed was Vascular surgery (VS) trainees, integrated residents and fellows, in the United States of America. Assessment of the personal impact of the pandemic on vascular surgery trainees and the coping strategies used by them were based on the validated Generalized Anxiety Disorder 7-item (GAD-7) scale and the validated 28-time Brief Coping Orientation to Problems Experienced (Brief-COPE) inventory. Results A total of 145 vascular surgery trainees responded to the survey, with a 23% response rate (145/638). Significant changes were made to the clinical responsibilities of VS trainees, with 111 (91%) reporting cancellation of elective procedures, 101 (82%) with call schedule changes, 34 (24%) with duties other than related to vascular surgery, and 29 (24%) participation in outpatient care delivery. Over one third (52/144) reported they had performed a procedure on a patient with confirmed COVID-19, 37 (25.7%) reported they were unaware of the COVID-19 status at the time. The majority continued to work after exposure (29/34, 78%). Major stressors included concerns about professional development, infection risk to family/friends, and impact of care delay on patients. Median score for GAD-7was 4 (IQR 1-8) which corresponds to no or low self-reported anxiety levels. VS trainees employed mostly active coping and rarely avoidant coping mechanisms, and the majority were aware and utilized social media and online support systems. No significant difference was observed between integrated residents and fellows, or by gender. Conclusions The pandemic has had significant impact on VS trainees. Trainees reported significant changes to clinical responsibilities, exposure to COVID-19 and pandemic-related stressors but demonstrated healthy coping mechanisms with low self-reported anxiety levels. The VS community should maintain awareness of the impact of the pandemic on the professional and personal development of surgeons in training.We recommend adaptive evolution in training to accommodate a the changing learning environment for trainees.

OBJECTIVE: Burnout is prevalent among vascular surgery trainees. Here we aim to identify modifiable risk factors for burnout in vascular surgery training, to facilitate the development of programs to enhance and sustain trainee well-being. METHODS: The Association of Program Directors in Vascular Surgery issued the Annual Training survey in the fall of 2018 to all trainees. The survey contained items to assess frequency of burnout, as well as mentorship, training environment, and stress coping mechanisms using an abbreviated COPE (Coping Orientation to Problems Experienced) inventory. RESULTS: Of 628 surveys issued, the response rate was 30% (n = 188). Respondents indicated that the majority of programs offer mentorship opportunities (n = 150 [83%]) that are longitudinal throughout the duration of training (n = 140 [77%]). Fifty-eight percent (n = 109) indicated there was an appropriate balance between learning and productivity in their program, with more respondents leaning toward too much clinical productivity (n = 57) and fewer toward too much learning (n = 19). Forty-five percent of respondents indicated feeling burnout at least weekly (n = 81). The burnout group was less likely to report an appropriate balance between clinical productivity and learning (49.4% vs 67.7%; P < .001), as well as a lower frequency of mentorship opportunities (72.1% vs 92.7%; P < .001). Certain coping skills were used more frequently in the burnout group, including self-distraction, disengagement, humor, self-blame, and substance use. In multivariate analysis, frequent use of self-blame conferred a 9.847-fold increased risk (95% confidence interval, 2.114–45.871) of burnout (P = .003), while feeling appropriately challenged by the faculty was significantly protective (odds ratio for burnout, 0.158; 95% confidence interval, 0.031–0.820; P = .03). CONCLUSIONS: The protective effect against vascular surgery trainee burnout conferred by the availability of mentorship suggests that an expansion and emphasis on mentorship in training may help to mitigate trainee burnout. Mentorship may also be a suitable channel to assess for an appropriate level of challenge, as well as for an appropriate balance between clinical productivity and learning that, when present, are also protective against burnout. Furthermore, the correlation between the frequent use of certain coping skills and burnout highlight this as an area for intervention, potentially through a combination of mentor modeling and formal training on healthy stress-related coping strategies.

Background The impact of the coronavirus disease 19 (COVID-19) pandemic on health care workers has been substantial. However, the impact on vascular surgery (VS) trainees has not yet been determined. The goals of our study were to gauge the impact of COVID-19 on VS trainees’ personal and professional life and to assess stressors, coping, and support structures involved in these trainees' response to the COVID-19 pandemic. Methods This was an anonymous online survey administered in April 12–24, 2020 during the surge phase of the global COVID-19 pandemic. It is a subset analysis of the cross-sectional Society for Vascular Surgery Wellness Committee Pandemic Practice, Anxiety, Coping, and Support Survey. The cohort surveyed was VS trainees, integrated residents and fellows, in the United States of America. Assessment of the personal impact of the pandemic on VS trainees and the coping strategies used by them was based on the validated Generalized Anxiety Disorder 7-item (GAD-7) scale and the validated 28-time Brief Coping Orientation to Problems Experienced inventory.

Over one-third (52/144) reported they had performed a procedure on a patient with confirmed COVID-19; 37 (25.7%) reported they were unaware of the COVID-19 status at the time. The majority continued to work after exposure (29/34, 78%). Major stressors included concerns about professional development, infection risk to family/friends, and impact of care delay on patients. The median score for GAD-7 was 4 (interquartile range 1–8), which corresponds to no or low self-reported anxiety levels. VS trainees employed mostly active coping and rarely avoidant coping mechanisms, and the majority were aware and used social media and online support systems. No significant difference was observed between integrated residents and fellows, or by gender. Conclusions The pandemic has had significant impact on VS trainees.

Recanalization of chronic iliofemoral deep vein thrombosis is indicated to reduce symptoms and improve quality of life. However, recanalization is dependent on the ability to cross chronic obstructions. We present a case of chronically thrombosed inferior vena cava and common iliac veins that failed conventional crossing techniques but were successfully recanalized using the recently approved Upstream GoBack Crossing Catheter.

Background The coronavirus disease 2019 (COVID-19) pandemic has led to unprecedented challenges for health care systems globally. We designed and administered a global survey to examine the effects of COVID-19 on vascular surgeons and explore the COVID-19-related stressors faced, coping strategies used, and support structures available. Methods The Pandemic Practice, Anxiety, Coping, and Support Survey for Vascular Surgeons was an anonymous cross-sectional survey sponsored by the Society for Vascular Surgery Wellness Task Force. The survey analysis evaluated the effects of COVID-19-related stressors on vascular surgeons measured using the Generalized Anxiety Disorder 7-item scale. The 28-item Brief Coping Orientation to Problems Experienced inventory was used to assess the active and avoidant coping strategies. Survey data were collected using REDCap (Research Electronic Data Capture) from April 14, 2020 to April 24, 2020 inclusive. Additional qualitative data were collected using open-ended questions. Univariable and multivariable analyses of the factors associated with the anxiety levels and qualitative analysis were performed. Results A total of 1609 survey responses (70.5% male; 82.5% vascular surgeons in practice) from 58 countries (43.4% from United States; 43.4% from Brazil) were eligible for analysis. Some degree of anxiety was reported by 54.5% of the respondents, and 23.3% reported moderate or severe anxiety. Most respondents (∼60%) reported using active coping strategies and the avoidant coping strategy of “self-distraction,” and 20% used other avoidant coping strategies. Multivariable analysis identified the following factors as significantly associated with increased self-reported anxiety levels: staying in a separate room at home or staying at the hospital or a hotel after work (odds ratio [OR], 1.39; 95% confidence interval [CI], 1.08-1.79), donning and doffing personal protective equipment (OR, 1.81; 95% CI, 1.41-2.33), worry about potential adverse patient outcomes due to care delay (OR, 1.47; 95% CI, 1.16-1.87), and financial concerns (OR, 1.90; 95% CI, 1.49-2.42). The factors significantly associated with decreased self-reported anxiety levels were hospital support (OR, 0.83; 95% CI, 0.76-0.91) and the use of positive reframing as an active coping strategy (OR, 0.88; 95% CI , 0.81-0.95). Conclusions Vascular surgeons globally have been experiencing multiple COVID-19-related stressors during this devastating crisis. These findings have highlighted the continued need for hospital systems to support their vascular surgeons and the importance of national societies to continue to invest in peer-support programs as paramount to promoting the well-being of vascular surgeons during and after the COVID-19 pandemic.

Background COVID-19 predisposes patients to a prothrombotic state with demonstrated microvascular involvement. The degree of hypercoagulability appears to correlate with outcomes; however, optimal criteria to assess for the highest-risk patients for thrombotic events remain unclear; we hypothesized that deranged thromboelastography measurements of coagulation would correlate with thromboembolic events. Study design Patients admitted to an ICU with COVID-19 diagnoses who had thromboelastography analyses performed were studied. Conventional coagulation assays, d-dimer levels, and viscoelastic measurements were analyzed using a receiver operating characteristic curve to predict thromboembolic outcomes and new-onset renal failure. Results Forty-four patients with COVID-19 were included in the analysis. Derangements in coagulation laboratory values, including elevated d-dimer, fibrinogen, prothrombin time, and partial thromboplastin time, were confirmed; viscoelastic measurements showed an elevated maximum amplitude and low lysis of clot at 30 minutes. A complete lack of lysis of clot at 30 minutes was seen in 57% of patients and predicted venous thromboembolic events with an area under the receiver operating characteristic curve of 0.742 (p = 0.021). A d-dimer cutoff of 2,600 ng/mL predicted need for dialysis with an area under the receiver operating characteristic curve of 0.779 (p = 0.005). Overall, patients with no lysis of clot at 30 minutes and a d-dimer > 2,600 ng/mL had a venous thromboembolic event rate of 50% compared with 0% for patients with neither risk factor (p = 0.008), and had a hemodialysis rate of 80% compared with 14% (p = 0.004). Conclusions Fibrinolysis shutdown, as evidenced by elevated d-dimer and complete failure of clot lysis at 30 minutes on thromboelastography predicts thromboembolic events and need for hemodialysis in critically ill patients with COVID-19. Additional clinical trials are required to ascertain the need for early therapeutic anticoagulation or fibrinolytic therapy to address this state of fibrinolysis shutdown.

Abstract. Although management paradigms for certain arterial trauma, such as aortic injuries, have moved towards an endovascular approach, the application of endovascular techniques for the treatment of peripheral arterial injuries continues to be debated. In the realm of peripheral vascular trauma, popliteal arterial injuries remain a devastating condition with significant rates of limb loss. Expedient management is essential and surgical revascularization has been the gold standard. Initial clinical assessment of vascular injury is aided by readily available imaging techniques such as duplex ultrasonography and high resolution computed tomographic angiography. Conventional catheter based angiography, however, remain the gold standard in the determination of vascular injury. There are limited data examining the outcomes of endovascular techniques to address popliteal arterial injuries. In this review, we examine the imaging modalities and current approaches and data regarding endovascular techniques for the management popliteal arterial trauma.

Aortic aneurysm is a disease predominately affecting the elderly. Since Parodi revolutionized the treatment with the development of endovascular aortic aneurysm repair in the 1990s, the utilization is increasing, with the elderly representing the fastest growing segment of the population. When considering endovascular or open surgery in the aging population, the untreated aneurysm should be considered the major driving factor in late mortality rather than a patient’s other comorbidities. The goal of aneurysm repair is to reduce risk of death from rupture. Patient comorbidities factor into estimating the degree in which someone will benefit from prophylactic repair. Patients with a high risk of rupture and minimal comorbidities should be offered repair. Open repair is tolerated poorly in the elderly population. Endovascular repair offers decreased mortality; however, patients may require secondary interventions and require lifelong surveillance.

Endovascular treatment of aortic arch aneurysms with a proximal landing zone in zone I requires carotid-carotid bypass. We report two patients with aortic arch aneurysms in whom we used a new hybrid approach by transposing the left common carotid artery and left subclavian artery to the right common carotid artery. This innovative technique uses a native vessel instead of prosthetic material and a shunt to maintain cerebral perfusion, thereby avoiding bilateral carotid clamping.
