Abstract
- Purpose: To evaluate the feasibility, safety, and outcome of transcatheter embolization using ethylene vinyl alcohol copolymer (EVOH) of type I endoleaks associated with endovascular abdominal aortic aneurysm repair. Patient Population and Methods: Retrospective chart review was performed to identify 8 consecutive patients who had undergone EVOH embolization for type I endoleaks between 2012 and 2015. The primary approach used to access the endoleak was the perigraft technique, where the endoleak itself is catheterized at the anastomotic site. Results: Six type Ia and 2 type Ib endoleaks were treated. In 2 patients, a direct transabdominal approach was used to access the endoleak because it was inaccessible via the perigraft approach. Coils were used in addition to EVOH in 5 cases. Residual endoleak was noted in 1 case, whereas 2 patients developed a recurrent type I endoleak during follow-up. No EVOH complications were observed. The 5 remaining patients demonstrated freedom from endoleak and reintervention at a mean follow-up of 6.9 months. Conclusion: Type I endoleaks can be safely and effectively treated by embolotherapy with EVOH. Larger endoleaks resulting from grossly undersized endografts appear to be unsuitable for EVOH embolization. [ABSTRACT FROM AUTHOR]
