Objective The aim of this study is to compare how instructions for use (IFU) affected peri-operative and intermediate term outcomes for common iliac artery aneurysms (CIAA) treated with the GORE EXCLUDER iliac branch endoprosthesis (IBE). Methods A retrospective analysis was performed of all patients treated at two affiliated academic centers from...

Background Iliac artery anatomy can have a dramatic impact on the success of endovascular complex aortic aneurysm (CAA) procedures as endograft delivery systems need to be advanced and manipulated through these access vessels.

Purpose : To report a case of a symptomatic type IIIb endoleak treated by a transgraft embolization approach. Case description : A 66-year-old Caucasian male with a 5.7 cm type IV thoracoabdominal aneurysm (TAAA), which was previously urgently repaired with a four-vessel physician-modified endovascular graft (PMEG), presented with worsening of bac...

Background-objective: PAD is a significant cause of morbidity and mortality affecting over 200 million people worldwide. Current guidelines recommend at least a single antiplatelet or anticoagulant agent in symptomatic PAD and lifelong antithrombotic treatment after a revascularization procedure. The aim of this systematic review and meta-analysis...

Introduction General surgery residency involves performing subspecialty procedures in addition to the core general procedures. However, the proportion of core general surgery versus subspecialty procedures during training is variable and its temporal changes are unknown. The goal of our study was to assess the current trends in core general surgery...

Objective Atherectomy has become increasingly used as an endovascular treatment of lower extremity atherosclerotic disease in the United States. Concerns and controversies about its indication and outcomes exist. The goal of this systematic review and meta-analysis was to investigate the outcomes and complications related to atherectomy to treat fe...

Purpose: The treatment of thoracoabdominal aortic aneurysm has largely shifted to endovascular techniques. However, severe iliofemoral arterial disease often presents a challenge during these interventions. As a result, iliac conduits have been introduced to facilitate aortic endovascular therapy. The goal of the current study was to gauge utiliza...

Introduction: Cancer results in a hypercoagulable state that is associated with both venous and arterial thromboses, but little is known about the impact of acute limb ischemia (ALI) in this cohort of patients. The goal of this systematic review and meta-analysis was to analyze the available clinical data on cancer and its association with ALI and...

Objective: Carotid artery stenosis is a determinant factor accused for cerebrovascular events, estimated to be the cause of 10-20% of all ischemic strokes. Trans-cervical carotid artery revascularization (TCAR) has been offered as an alternative to transfemoral carotid artery stenting and carotid endarterectomy. Methods: A systematic review and...

Introduction Treatment of cancer-associated venous thromboembolism (CAVTE) remains challenging. The aim of this study was to assess the outcomes of direct acting oral anticoagulants (DOAs) for the treatment of CAVTE. Materials and methods A network meta-analysis of randomized clinical trials comparing DOAs (Apixaban, Rivaroxaban, and Edoxaban) ver...

Objectives The COVID-19 pandemic resulted in the cancellation of in-person testing across the country. We sought to understand the feasibility of conducting virtual oral examinations as well as solicit opinions of vascular surgery program directors regarding the use of virtual platforms to conduct both low stakes mock oral examinations with their t...

Introduction Many educational institutions and academic organizations provide concise and highly organized educational material for the trainees and training programs, while others do not. The role of interactive technology-enhanced learning in surgical education is not entirely explored and disseminated despite common knowledge of such interactive...

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 success...

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, a...

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-s...

The American Venous Forum (AVF) and the Society for Vascular Surgery set forth these guidelines for the management of endothermal heat-induced thrombosis (EHIT). The guidelines serve to compile the body of literature on EHIT and to put forth evidence-based recommendations. The guidelines are divided into the following categories: classification of...

Introduction The coronavirus disease 2019 (COVID-19) pandemic has led to widespread postponement and cancelation of elective surgeries in the United States. We designed and administered a global survey to examine the impact of COVID-19 on vascular surgeons. We describe the impact of the pandemic on the practices of Vascular Surgeons in the United S...

Introduction 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 impact of COVID-19 on vascular surgeons and explore the COVID-19 related stressors faced, coping strategies employed, and support structures available Method...

Carotid artery disease and stroke account for the second cause of mortality in worldwide. Recently, transcarotid artery stenting (TCAR) has emerged as a treatment modality that carries the lowest a very low stroke rate. However, there are limitations to TCAR, such as heavily calcified plaques that might preclude optimal stent expansion. We describe...

Background Acute limb ischemia (ALI) carries significant overall morbidity and mortality. Pregnant and postpartum women are physiologically hypercoagulable, but little is known about the impact of ALI in this cohort of patients. The goal of this systematic review was to gather available data on diagnosis and treatment of ALI during pregnancy and th...

Ruptured thoracoabdominal aneurysms (rTAAA) are rare and carry a significant rate of morbidity and mortality. Aortocaval fistula secondary to rTAAA are even more infrequent. We describe an urgent and staged endovascular treatment of a ruptured extent III thoracoabdominal aortic aneurysm with an aortocaval fistula by performing vena cava stenting to...

Objective: Upper extremity access (UEA) is an important component of complex fenestrated and branched endovascular aneurysm repair (F/BEVAR). Open and percutaneous UEA approaches have been reported during these procedures. The aim of this review was to assess the outcomes of UEA done to facilitate F/BEVAR. Methods: A systematic review of studies...

Diagnosis of PTS is based on history and clinical presentation. The syndrome consists of signs and symptoms of heaviness, intolerance to exercises, pain, leg edema, paresthesia, cramps, and pruritus that may evolve to skin damage, such as hyperpigmentation, lipodermatosclerosis, and ulcers. PTS generates high expenses for government and insurance c...

Understanding venous pathophysiology is the starting point to treat chronic venous disease (CVD) but most importantly to prevent its complication. CVD can be subdivided into congenital, primary, and secondary venous disease. Primary venous disease is the most prevalent form of the disease affecting two-thirds of patients with CVD. It is caused by a...
