One-Year Clinical Outcomes Following Mechanical Thrombectomy for Deep Vein Thrombosis: A CLOUT Registry Analysis.

Background: Mechanical thrombectomy is a promising treatment option for deep vein thrombosis; however, long-term data are lacking. Here, we report for the first time the 1-year clinical outcomes from the completely enrolled ClotTriever Outcomes (CLOUT) registry evaluating mechanical thrombectomy with the ClotTriever System (Inari Medical).

Methods: The CLOUT registry (NCT03575364) is a prospective, multicenter, single-arm study that enrolled 500 patients with proximal lower extremity deep vein thrombosis.

Trauma bypass performed by vascular surgeons demonstrate excellent long-term outcomes and limb preservation.

Objective: Long-term outcomes in civilian trauma patients requiring upper or lower extremity revascularization is poorly studied secondary to limitations of certain large databases and the nature of the patients in this specific vascular subset. This study reports on the experience and outcomes of a Level 1 trauma center that serves both an urban and a large rural population over a 20-year period to identify bypass outcomes and surveillance protocols.

Methods: Database of a single vascular group at an academic center was queried for trauma patients requiring upper or lower extremity revascularization between January 1, 2002, and June 30, 2022.

Use of the right retroperitoneum as an alternative approach to the abdominal aorta.

Objective: The left retroperitoneal approach to the aorta is a well-established technique for aortic exposure. The right retroperitoneal approach to the aorta is performed less commonly, and the outcomes remain unknown. This study aimed to evaluate the outcomes of right retroperitoneal aortic-based procedures and to determine its utility in aortic reconstruction when faced with hostile anatomy or infection in the abdomen or left flank.

Prosthetic versus native artery inflow for infrainguinal bypass.

Background: Infrainguinal bypass performed after previous prosthetic inflow reconstruction offers a choice of where to perform the proximal anastomosis. The hood of a previous inflow bypass might be technically easier to isolate during reoperative surgery. However, the more distal native artery might offer better patency to the outflow revascularization.

Chimney stent graft for left subclavian artery preservation during thoracic endograft placement.

Objective: Carotid to subclavian artery bypass (CSB) has been the standard for revascularizing the left subclavian artery during coverage by thoracic endovascular aortic repair (TEVAR). The purpose of this study is to determine if a chimney stent graft (CSG) offers similar outcomes as an alternative to open bypass.

Methods: A retrospective review of a single vascular surgery registry between February 2011 and September 2017 was performed of all left subclavian revascularization during elective TEVAR.

Outcomes for carotid endarterectomy in nonagenarians.

Objective: Carotid endarterectomy (CEA) is a well-established procedure with prospective randomized data demonstrating the benefit of stroke prevention. With the aging of the population, there are limited data published for nonagenarians, especially for asymptomatic stenosis. This study investigated 30-day morbidity and mortality as well as late survival in symptomatic and asymptomatic nonagenarians with severe carotid stenosis undergoing CEA.

Effects of endovascular first strategy on spliced vein bypass outcomes.

Objective: Aggressive endovascular interventions for patients without adequate full-length venous conduit have gained popularity. The purpose of this study is to evaluate the outcomes of spliced vein bypass (SVB) as primary treatment versus treatment after failed endovascular intervention (endovascular SVB [ESVB]) for infrainguinal revascularization.

Methods: A retrospective analysis of a single vascular group's database of all SVBs was queried for demographics, indications, intraoperative details, and outcomes.

Long-term patency of venous and prosthetic conduits for ipsilateral internal carotid artery bypass.

Objective: Ipsilateral internal carotid artery bypass has been used successfully to treat aneurysms, infection, tumor, and occlusive disease. The purpose of this study was to evaluate the long-term outcomes of autogenous and prosthetic conduits used for ipsilateral internal carotid artery bypass.

Methods: A retrospective review of a single-institution registry was performed to identify patients with ipsilateral carotid artery bypass.

Percutaneous axillary artery access for endovascular interventions.

Background: As endovascular therapy becomes increasingly complex, adjunct techniques such as upper extremity arterial access facilitate visceral branch interventions. The purpose of this study was to assess the viability of axillary artery percutaneous access in endovascular repair.

Methods: Records of all patients undergoing axillary artery percutaneous access as part of an endovascular intervention from December 2015 to December 2016 were examined.

Percutaneous common femoral artery interventions using angioplasty, atherectomy, and stenting.

Background: This study evaluated the feasibility, safety, and effectiveness of endovascular interventions for common femoral artery (CFA) occlusive disease.

Methods: Using a prospectively maintained multicenter database, we analyzed outcomes in 167 consecutive patients who underwent percutaneous CFA interventions for Rutherford class 3 to class 6 (R3-R6) disease. The standardized treatment approach included primary percutaneous transluminal angioplasty (PTA) only, atherectomy + PTA, and provisional stenting.

Carotid interventions (CEA and CAS) in acute stroke patients: which procedure on which patient.

Treatment of carotid bifurcation disease in patients presenting with acute stroke has been a controversial issue over the past four decades. Classically, patients were asked to wait four to six weeks before intervention was entertained in order for the brain to stabilize and the risks of intervention to be minimized. Unfortunately, up to 20% of patients will have a secondary event after their index event and the window of opportunity to save potentially salvageable ischemic tissue will be missed.

Comparative results of open lower extremity revascularization in nonagenarians.

Introduction: The average lifespan in the United States continues to lengthen. We have observed a similar trend in our patients, with an increased number of nonagenarians presenting for evaluation of vascular disease. This study evaluated outcomes of lower extremity revascularization in patients aged >or=90 years.

Strategies to improve spinal cord ischemia in endovascular thoracic aortic repair: Outcomes of a prospective cerebrospinal fluid drainage protocol.

Purpose: Although endovascular repair of thoracic aortic aneurysm has been shown to reduce the morbidity and mortality rates, spinal cord ischemia remains a persistent problem. We evaluated our experience with spinal cord protective measures using a standardized cerebrospinal fluid (CSF) drainage protocol in patients undergoing endovascular thoracic aortic repair.

Methods: From 2004 to 2006, 121 patients underwent elective (n = 52, 43%) and emergent (n = 69, 57%) endovascular thoracic aortic stent graft placement for thoracic aortic aneurysm (TAA) (n = 94, 78%), symptomatic penetrating ulceration (n = 11, 9%), pseudoaneurysms (n = 5, 4%) and traumatic aortic transactions (n = 11, 9%).
