摘要

Purpose

To compare the outcomes of chimney endovascular aneurysm repair (Ch-EVAR) and open surgical repair (OSR) for abdominal aortic aneurysm (AAA) in consideration of the lack of comparative evidence.

Methods

The subjects of this retrospective study were patients who underwent elective Ch-EVAR or OSR for short-neck AAAs between 2013 and 2020 at five vascular centers. The primary endpoint was 30-day mortality and the secondary endpoints were postoperative complications and midterm clinical outcomes, including renal function changes, reintervention, overall survival, and aneurysm-related mortality.

Results

We analyzed 38 Ch-EVARs and 42 OSRs. The 30-day mortality rates were 2.6 and 2.4% in the Ch-EVAR and OSR groups, respectively (P = 1.00). The acute kidney injury incidence was higher in the OSR group than in the Ch-EVAR group (P < 0.01). The freedom from reintervention rate at 5 years was lower in the Ch-EVAR group than in the OSR group (81.0% vs. 100%, P = 0.04). Other midterm clinical outcomes did not differ between the groups.

Conclusions

Ch-EVAR may be a feasible treatment option for short-neck AAA; however, it should be limited to patients at high operative risk for OSR, considering the concern about its long-term durability.
