Primary iliac venous aneurysm is an exceedingly rare abnormality that can be complicated by pulmonary embolism, thrombosis, and rupture. Here we report the case of an otherwise healthy 40-year-old man with a unilateral external iliac vein aneurysm without any evidence of an arteriovenous fistula, proximal stenosis, or obstruction, as reported on computed tomography. Pulmonary embolism was diagnosed using Tc-macroaggregated albumin scintigraphy. To prevent life-threatening complications, we treated the patient with anticoagulant therapy and performed aneurysmectomy with reconstruction using a saphenous vein graft patch. Although postoperative venography showed obstruction of the external iliac vein, the patient remained asymptomatic.

Background: The first pancreas transplant in Australia was performed at Prince Henry's Hospital in 1984 (which subsequently relocated to Monash Medical Centre in 1992) in the setting of a successful pancreas transplant reported from the University of Minnesota in 1966. This study is aimed at reviewing the evolution of surgical technique in pancreas transplants and the surgical outcomes.

Methods: All pancreas transplants were reviewed from 1992 to 2022.

Background: Visceral malperfusion is a serious complication of acute aortic dissection. Currently, diagnosis relies on signs of end-organ failure, which may be clinically obscure and delay crucial treatment.

Objective: The aim was to investigate external iliac (IA) and superior mesenteric artery (SMA) pressures in cases where both vessels originate exclusively from the true lumen to develop and validate a novel early indicator of visceral malperfusion.

Introduction: The superiority of indocyanine green fluorescence angiography (ICG-FA) to the clinical eye alone to assess tissue perfusion has been demonstrated in various surgical fields. This short report demonstrates the use of ICG-FA to assess skin perfusion before ligating the external iliac artery (EIA) to exclude a common femoral artery (CFA) aneurysm.

Report: A 70-year-old man presented with a CFA aneurysm after a previous transfemoral amputation.

Objective: Infected femoral artery pseudoaneurysms (IFAPs) are threatening complications of voluntary drug injections in the groin. The purpose of this study is to report the results of open and endovascular repair of IFAPs in intravenous drug abusers.

Methods: The IN-FEMS (INfected Femoral artery psEudoaneurysMs in drug addictS) is a physician-initiated, multicenter and retrospective registry of patients treated for native IFAPs between 2010 and 2023 in 18 different Italian Vascular Surgery Departments.

Background: Endovascular aneurysm repair (EVAR) is widely used to treat abdominal aortic aneurysm (AAA). However, it carries the risk of complications that often require further interventions. Endograft limb occlusion (ELO), though relatively rare, significantly affects patient outcomes.
