ABSTRACT
PURPOSE:
To evaluate the safety and efficacy of covered stents for treatment of visceral artery aneurysms (VAA).METHODS:
This multicenter retrospective study included patients with VAAs who were treated with covered stents between January 2015 and December 2020. A total of 65 patients (mean age, 58 years; range, 27-89 years) with 70 VAAs (60 true aneurysms [86%], 10 pseudoaneurysms [14%]) were included. Of the 65, 48 patients (74%) were asymptomatic. Patient demographics, endovascular treatments, and follow-up results were analyzed.RESULTS:
All patients received covered stents. The mean diameter was 2.9 cm (range, 1.0-7.6 cm) for symptomatic aneurysms and 2.5 cm (range, 1.0-9.0 cm) for asymptomatic aneurysms. Of the asymptomatic aneurysms, 89% had a saccular shape. The mean distance between the ostium of the artery in which the aneurysm occurred and the aneurysm was 3.9 cm (median, 3.0 cm; range, 0.5-10 cm). Additional coil embolization was used in 7 aneurysms (10%). During the procedure, 68 (97%) aneurysms were completely excluded, while 2 (3%) had a Type Ib endoleak. After a mean follow-up of 20 months (range, 1-75 months), all patients were asymptomatic. Four endoleaks were recorded and left for close observation. Four stents (7%) had mild restenosis, while the rest of the stents were patent.CONCLUSIONS:
Placement of covered stents in patients with VAAs excluded aneurysms and maintained artery patency.
