Abstract Background Stimulated by published reports of potentially inappropriate application of venous procedures, the American Venous Forum and its Ethics Task Force in collaboration with multiple other professional societies including the Society for Vascular Surgery (SVS), American Vein and Lymphatic Society (AVLS), and the Society of Interventional Radiology (SIR) developed the appropriate use criteria (AUC) for chronic lower extremity venous disease to provide clarity to the application of ...

Abstract Objective The purpose of this study was to report the updated results of a prospective, multicenter, nonrandomized, single-arm investigational device exemption study conducted at 17 sites in the United States to assess safety and effectiveness of the Zenith Alpha thoracic endovascular graft (Cook Medical, Bloomington, Ind) for treatment of blunt thoracic aortic injury (BTAI). Methods The primary safety end point was 30-day all-cause mortality and aortic injury-related mortality. The pri...

Abstract Background Standardized databases such as the Vascular Quality Initiative and National Surgical Quality Improvement Project assess the quality of care related to common vascular surgery procedures, but are not designed for uncommon vascular diseases. We describe a method of assessing uncommon vascular diseases using a multi-institutional collaboration, the Vascular Low Frequency Disease Consortium (VLFDC). Methods Uncommon vascular diseases are identified through a systematic literature...

Abstract Objective Vascular Ehlers-Danlos syndrome (vEDS) is a rare disorder and 1 of 13 types of EDS. The syndrome results in aortic and arterial aneurysms and dissections at a young age. Diagnosis is confirmed with molecular testing via skin biopsy or genetic testing for COL3A1 pathogenic variants. We describe a multi-institutional experience in the diagnosis of vEDS from 2000 to 2015. Methods This is a multi-institutional cross-sectional retrospective study of individuals with vEDS. The insti...

Abstract Background Black end-stage renal disease (ESRD) patients represent 30.5% of the prevalent ESRD population in the United States, despite only accounting for 18% of the total population. Black patients are less likely to have pre-ESRD care compared to their white counterparts, and are 3 to 4 times more likely to progress from chronic kidney disease to ESRD than whites, suggesting black patients are particularly vulnerable to disparities in outcomes related to hemodialysis and ESRD. The ob...

Abstract Background The en bloc resection of inferior vena cava (IVC) leiomyosarcoma often necessitates IVC reconstruction. The objective of this study is to examine outcomes after IVC reconstruction and determine optimal graft sizing. Method A retrospective review was conducted of all IVC reconstructions after IVC leiomyosarcoma resection at a single institution. Cross sectional dimensions at the IVC resection margins were measured on pre-operative imaging. The tumor location was based on the m...

Abstract Background Venous resection during pancreaticoduodenectomy for the excision of pancreatic cancer allows for a more complete resection with negative margins, which increases survival. When the resected vein is greater than 3cm, reconstruction with an interposition graft is recommended. However, consensus regarding the optimal venous conduit has not been reached. The objective of this study is to compare outcomes between the paneled saphenous vein graft (SVG) and internal jugular vein gra...

Abstract Objective Vascular Ehlers-Danlos syndrome (vEDS) is a rare connective tissue disorder owing to pathogenic variants in COL3A1 that lead to impaired type III collagen production. We aim to describe the contemporary multi-institutional experience of aortic and arterial pathology in individuals with vEDS, to evaluate disease patterns and refine management recommendations. Methods This cross-sectional, retrospective study of individuals with genetically confirmed vEDS was conducted between 2...
