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

Completed

• Conditions: Abdominal Aortic Aneurysm

• Registration Number: NCT03952780
• Lead Sponsor: Yonsei University

Brief Summary

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

Name	Time	Method
Technical success	At the end of the procedure	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.

Secondary Outcome Measures

Name	Time	Method
Aneurysm-related event	1 year	Aneurysm-related event (aneurysm-related death, reintervention, and aorta expansion\> 5 mm, device migration, conversion to open repair, stent graft fracture, stent graft occlusion) at 1 year
Major adverse event	1 year	Major adverse event, a composite of death, myocardial infarction, stroke, or renal failure requiring dialysis) at 1 year
Aneurysm-related death	1 year	Aneurysm-related death at 1 year
Reintervention	1 year	Reintervention at 1 year
Type I/III endoleaks	1 year	Type I/III endoleaks at 1 year
All vascular complications related to the INCRAFT device or aneurysm requiring surgical or endovascular interventions	30 days	All vascular complications at 30 days related to the INCRAFT device or aneurysm requiring surgical or endovascular interventions
Number of closure devices used for the closure of access sites.	30 days	Number of closure devices used for the closure of access sites.
