Korean Registry of Percutaneous EVAR With INCRAFT Stent Graft for the Treatment of Abdominalaortic Aneurysm (K-INCRAFT)

The sudy purpose is to investigate efficacy and safety of percutaneous endovascular aortic aneurysm repair using INCRAFT stent graft for Korean patients with abdominal aortic aneurysm. This study is designed as an investigator-initiated, multi-center, single-arm, prospective registry study. A total of 100 patients who meet all inclusion criteria, but none of exclusion criteria will be enrolled after the implantation of INCRAFT stent graft. The primary efficacy outcome is technical success defined as successful deployment of the stent-graft with no type I/III endoleak, unintentional coverage of visceral aortic branches or internal iliac arteries at the end of the procedure, and with successful removal of the delivery system. The primary safety outcome is major vascular complications at 30 days including. The study subjects will be followed for 12 months.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Technical success	Technical success defined as successful deployment of the stent-graft with no type I/III endoleak, unintentional coverage of visceral aortic branches or internal iliac arteries at the end of the procedure, and with successful removal of the delivery system. Primary conversion or additional implantation of bare metal stent, aortic cuff or EndoAnchors to treat type I endoleak is considered a technical failure.	At the end of the procedure
