Ultrasound-Guided Transgraft and Transcaval Embolization of Type II Endoleak

Abstract

Type II endoleak is a common and often unavoidable complication following endovascular aortic aneurysm repair. Most endoleaks are transient and will either resolve spontaneously or remain benign. However, persistent type II endoleaks can be associated with aneurysmal sac expansion and, even, rupture. The optimal treatment strategy for these endoleaks depends on the source, location, and collateral network of the feeding vessels. The most frequent strategies for embolization include transarterial access of the feeding vessel and translumbar embolization via direct sac puncture.
