A Case of Renal Arteriovenous Malformation with a Venous Sac that Was Completely Embolized by Isolation and Packing via a Transarterial and Transvenous Approach

Abstract

The case of a woman in her 30s who was incidentally diagnosed as having a renal arteriovenous malformation (AVM) is described. The AVM was of the aneurysmal type and consisted of an aneurysm and a venous sac. We decided to perform coil embolization of the venous sac via a venous approach due to the complicated anatomy. It was possible to approach the venous sac from both the venous and arterial sides, allowing for complete occlusion through isolation and packing. Considering the patientʼs age, risk of postoperative recurrence, and complications, we consider that achievement of complete occlusion through transcatheter isolation and packing was significant.
