Outcomes of transcaval endoleak embolization via laser fenestration of the inferior vena cava following endovascular abdominal aortic aneurysm repair

Abstract

This report describes a single center experience with laser fenestration of the inferior vena cava for the treatment of type 2 endoleak after endovascular abdominal aortic aneurysm repair. Our technique is reviewed, and clinical data after treatment are reported. Twelve patients underwent transcaval embolization via laser fenestration. Technical success was achieved in all cases (100%) with no postoperative complications. At a median follow-up of 12.9 months, no patient demonstrated a persistent endoleak and there were no cases of aortocaval fistula. Transcaval embolization, via laser fenestration, provides an additional strategy for the management of type 2 endoleak after endovascular abdominal aortic aneurysm repair.
