BACKGROUND: Identification of a safe and effective medical therapy for abdominal aortic aneurysm (AAA) disease remains a significant unmet medical need. Recent small cohort studies indicate that metformin, the world's most commonly prescribed oral hypoglycemic agent, may limit AAA enlargement. We sought to validate these preliminary observations in a larger cohort. METHODS: All patients with asymptomatic AAA disease managed in the Veterans Affairs Health Care System between 2003 and 2013 were identified by International Classification of Diseases, Ninth Revision codes...

Chronic type B aortic dissection with aneurysmal degeneration requiring intervention presents significant therapeutic challenges. Thoracic endovascular aortic repair with a fenestrated endograft is a feasible option, but false lumen branches without an adjacent re-entry or perforation in the septum can pose a significant challenge. We present two cases of fenestrated endovascular aneurysm repair for chronic type B aortic dissection in which a renal artery from the false lumen was cannulated by creating a "neofenestration" through the dissection flap using a radiofrequency PowerWire (Baylis Medical Inc, Montreal, Quebec, Canada) technique (Toronto PowerWire fenestration technique)...

Termed hemosuccus pancreaticus by Sandblom in 1970, hemorrhage from the pancreatic duct into the gastrointestinal tract represents a rare and challenging problem. Patients present with repeated upper gastrointestinal bleeding that is intermittent but often self-limited. In most cases, this pathophysiologic process is secondary to pancreatitis, chronic inflammation, and subsequent splenic artery pseudoaneurysm bleeding. Previously treated with open splenectomy and distal pancreatectomy, hemosuccus pancreaticus is now often managed with minimally invasive endovascular means...

OBJECTIVE: We evaluated the association between postoperative hyperglycemia and outcomes after abdominal aortic aneurysm (AAA) repair. METHODS: We used diagnosis and procedure codes (International Classification of Diseases, Ninth Revision, Clinical Modification) to identify patients who underwent open or endovascular repair of a nonruptured AAA from September 2008 to March 2014 from the Cerner Health Facts database (Cerner Corporation, North Kansas City, Mo). We evaluated the association between postoperative hyperglycemia (glucose concentration >180 mg/dL) and infections, in-hospital mortality, readmission, patients' characteristics, length of hospital stay, and medications...

OBJECTIVE: Acute kidney injury (AKI) is a common postoperative complication after abdominal aortic aneurysm (AAA) repair and is associated with significant morbidity and mortality. However, limited studies have investigated this complication in elderly patients. This study aims to evaluate AKI in octogenarians after open endovascular AAA repair (OAR) and endovascular AAA repair (EVAR). METHODS: Data were obtained from the Vascular Quality Initiative database on all patients who underwent elective infrarenal AAA repair between January 2003 and April 2017...

OBJECTIVE: Renal function deterioration is an important determinant of mortality in patients treated for complex aortic aneurysms. We have previously determined that catheter and guidewire manipulation in diseased aortas during fenestrated-branched endovascular aneurysm repair (F-BEVAR) is associated with risk of renal function deterioration. The aim of this study was to describe the impact of atherothrombotic aortic wall thrombus (AWT) on renal function deterioration among patients treated by F-BEVAR for pararenal and extent IV thoracoabdominal aortic aneurysms...

BACKGROUND: Arteries, veins, and lymphatic vessels are distinguished by structural differences that correspond to their different functions. Each of these vessels is also defined by specific molecular markers that persist throughout adult life; these markers are some of the molecular determinants that control the differentiation of embryonic undifferentiated cells into arteries, veins, or lymphatics. METHODS: This is a review of experimental literature. RESULTS: The Eph-B4 receptor and its ligand, ephrin-B2, are critical molecular determinants of vessel identity, arising on endothelial cells early in embryonic development...

OBJECTIVE: Autologous vein is the preferred conduit for lower extremity bypass. However, it is often unavailable because of prior harvest or inadequate for bypass owing to insufficient caliber. Cryopreserved cadaveric vessels can be used as conduits for lower extremity revascularization when autogenous vein is not available and the use of prosthetic grafts is not appropriate. Many studies have shown that donor characteristics influence clinical outcomes in solid organ transplantation, but little is known regarding their impact in vascular surgery...
