Abstract

Visceral and renal artery aneurysms (VRAAs) and pseudoaneurysms are rare. Their increasing incidence is largely thought to be due to advances in medical imaging. Twenty percent of VRAAs occur in hepatic arteries, with approximately fifty percent of these represented by pseudoaneurysms, which are prone to spontaneous rupture. Many treatments for VRAAs exist, with the endovascular approach being favoured. Treatment aims to preserve visceral perfusion and exclude the aneurysm; however, complex aneurysms may require parent artery or end-organ sacrifice. Covered stents allow rapid aneurysm exclusion while preserving parent artery patency, a favourable outcome when parent artery or end-organ sacri..
