Mid-Term Outcomes of Endovascular Aneurysm Repair With the INCRAFT Stent Graft System: Retrospective Combined Korean Multi-Center and Single-Center Registry Analysis.
TL;DR
In Korean patients with AAA, the INCRAFT stent-graft system demonstrated favorable mid-term outcomes, with low rates of aneurysm-related mortality, acceptable reintervention rates, and stable aneurysm sac behavior.
Abstract
BACKGROUNDS AND
Objectives
Endovascular aneurysm repair is widely used for the management of abdominal aortic aneurysm (AAA). Although short-term outcomes are favorable, concerns persist regarding long-term durability, particularly due to higher rates of secondary reintervention. This study aimed to evaluate the mid-term clinical outcomes of the ultra-low-profile INCRAFT stent-graft system.
Methods
We analyzed 146 patients treated with the INCRAFT stent-graft system using a combined Korean multicenter prospective and single-center retrospective registry. Clinical follow-up was performed until the last clinical contact through electronic medical records, and imaging follow-up with computed tomography or ultrasonography was performed up to 3 years.
Results
During a median follow-up of 44 months, there were no cases of aneurysm-related death or aneurysm rupture. At 3-year follow-up, sac shrinkage was observed in 41.5%, whereas sac enlargement was noted in 9.6%. Endoleaks were observed in 24.5% at 3 years. Type II endoleak was the most frequent endoleak type and cause of reintervention. Reinterventions were required in 17.1% (n=25), predominantly due to endoleaks (9.6%) and limb-related complications (6.8%).
Conclusions
In Korean patients with AAA, the INCRAFT stent-graft system demonstrated favorable mid-term outcomes, with low rates of aneurysm-related mortality, acceptable reintervention rates, and stable aneurysm sac behavior.
