Abstract

Purpose

Endoleak is a common complication following endovascular aortic aneurysm repairs (EVAR). The aim of this study was to discover the frequency and characteristics after EVAR with on-label use.

Methods

A retrospective review was performed on 25 patients who underwent EVAR in Inha University Hospital between December 2005 and February 2009. The data included in this study accounted for patient characteristics, anatomic features, operative technical details, and types of devices used. The results of EVAR were analyzed for clinical success, technical success and endoleak.

Results

Endoleaks were observed during 11 (47.8%) procedures. Type I endoleaks were observed in 2 (18.2%) cases. A total of 6 type II intraoperative endoleaks (54.5%) were observed. 3 type III endoleaks (27.3%) occurred. But all endoleaks were resolved without additional intervention CT scan after 6 months.

Conclusion

Although the endovascular management of AAAs is less invasive than open surgery, many complications including endoleak were still the most common adverse event during the first postoperative month. However, observation may be a good treatment for minor endoleak after EVAR.

Keywords: Endoleak, Endovascular aneurysm repair (EVAR), Abdominal aortic aneurysm, Stent-graft
