Aim: The purpose of this study was to review the outcomes of endovascular treatment and open repair of visceral artery aneurysms, and to compare their results.
Methods: Between January 1995 and January 2009, 42 patients (22 males) underwent surgical or endovascular treatment for visceral artery aneurysms. Mean age was 60 ± 13 (range, 35-85). Overall, 12 patients (25%) were asymptomatic, twenty-six patients (54.2%) were symptomatic, and 10 aneurysms (20.8%) were ruptured. The first 12 cases (28.6%) were treated with open repair; thereafter, endovascular techniques were used to treat 30 VAAs (71.4%).
Results: Ten patients were treated in emergency setting [8 in the endovascular group (26.6%) and 2 in the open repair group (16.7%), P=0.491]. In the endovascular group, primary technical success was achieved in 29 of 30 VAAs (96.6%). Overall in-hospital mortality was 2.4%. Major complications occurred in 8 patients (3 endovascular vs 5 open repair, P=0.01). Overall, mean hospitalization was 9.7 vs. 13 days (P<0.0001). Mean follow-up was 64 months (range, 3 months-14 years). In the endovascular group, reperfusion was higher in larger (>5 cm) aneurysms (P<0.0001).
Conclusion: Endovascular techniques could be the first treatment option for all visceral artery aneurysms.
