Abdominal aortic hypoplasia is a rare vascular variant with possible major clinical sequelae when the renal arteries are also involved. The condition is thought to result from embryonic overfusion of the two dorsal aortas. The diagnosis may be considered in patients presenting with hypertension in the neonatal period and severely reduced or absent arterial pulses in the groin. We present contrast-enhanced state-of-the-art magnetic resonance angiography imaging findings in an 8-year-old boy with abdominal aortic hypoplasia.

The use of conventional contrast agents in computed tomography (CT) and magnetic resonance (MR) imaging is often limited in patients with chronic kidney disease (CKD) due to potential nephrotoxicity. Ferumoxytol, originally developed for iron supplementation, has emerged as a promising alternative MR contrast agent that is safer for patients with CKD. This study aims to present our center's experience with ferumoxytol as a contrast agent in CKD patients.

Adverse iliofemoral anatomy represents a unique challenge for endovascular aortic aneurysm repair (EVAR). This report describes a transaxillary EVAR in a patient with severe iliofemoral occlusive disease and an infrarenal aortic aneurysm. A reversely mounted Gore Excluder graft was advanced and deployed in the infrarenal aorta using the left axillary artery.

Background: Vascular calcification is common and progressive in patients with chronic kidney disease. However, the risk factors associated with the progression of vascular calcification in patients receiving maintenance dialysis have not been fully elucidated. Here, we aimed to evaluate vascular calcification and identify the factors associated with its progression in patients receiving maintenance hemodialysis.

Abdominal Aortic Aneurysm (AAA) poses a significant health risk due to its silent nature and high mortality upon rupture. The Fib-4 index, initially designed for liver fibrosis assessment, presents potential beyond its scope. This study aims to investigate the association of FIB-4 with aneurysm size and mortality risk, exploring its utility as a risk predictor for enhanced clinical management.

Objective: This study aimed to compare treatment outcomes between graft replacement and aneurysmorrhaphy with ligation of the aortic side branches for type 2 endoleaks after endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms.
Methods: We retrospectively analyzed multicenter data of patients who underwent open surgical conversion, including graft replacement or aneurysmorrhaphy with ligation of the aortic side branches (graft preservation) for the treatment of type 2 endoleaks between 2007 and 2022. The endpoints were postoperative complications, 30-day mortality, overall survival, and reintervention or sac expansion after open surgical conversion.
