Abstract

Introduction: Over the past decade, endovascular treatment (EVT) is taking over visceral arterial aneurysms treatment considering its effectiveness, safety and minimal invasiveness. Methods: We retrospectively evaluated our department experience in visceral arterial aneurysms endovascular approach from 2009 to 2019.

Results: From 2009 to 2019, nineteen visceral artery aneurysms were submitted to EVT (mean age 62,5 years, 53% women). The addressed arterial segments were: the splenic artery (52%, n=10) followed by the renal artery (21%, n = 4), the hepatic artery (11%, n = 2), the superior mesenteric artery (11%, n = 2) and the celiac arrtery (5%, n = 1). Average diameter was 26,9 ± 5,4 mm [range 21–39 mm]. The majority were asymptomatic incidental findings (74%). Concomitant aneurysms were found in 3 patients (15,8%). EVT included: stent-graft exclusion (n = 9), aneurysm-sac coil embolization (n = 6), stent-assisted coil embolization (n=2) and segmental artery exclusion (n=2). Median radiological follow-up was 46,8 months [range 1,1–128 months]. Early SMA occlusion was reported in one case after stent-assisted coil embolization, however without ischemic symptoms. End-organ loss was reported in one case (renal artery coil embolization, without overall renal function worsening).

Conclusion: Nowadays, endovascular approach is the first-line intervention for most visceral arterial aneurysms. Although still limited, the reported results are favourable and are in line with the current literature.
