Effect of detachable fibered coils occlusion system on visceral artery aneurysms / 中华老年心脑血管病杂志

ABSTRACT

Objective To study the safety and efficacy of detachable fibered coils occlusion system for visceral artery aneurysms.Methods Thirty-three visceral artery aneurysms patients (12 males and 21 females) with an average age of 63.8±3.5 years who underwent endovascular embolization with detachable fibered coils occlusion system combined with standard pushable coils in our hospital were included in this study.Of these patients,20 (60.6％),7 (21.2％),3 (9.1％),2 (6.1 ％),and 1 (3.0％) were respectively diagnosed with splenic artery aneurysm,renal aneurysm,superior mesenteric aneurysm,celiac aneurysm,and pancreaticoduodenal aneurysm.The mean diameter of aneurysms was 16-38 (24.0±3.4)mm.The success rate of detachable fibered coils occlusion system for visceral artery aneurysms,postoperative complications and surgical procedure time were recorded.The patients received CT or ultrasonographic follow up at months 3,6,12 and every year after operation.Results The success rate of detachable fibered coils occlusion system for visceral artery aneurysms was 100％.No intraoperative bleeding and coil migration occurred.One patient with splenic artery dissection did not undergo operation.The patients were followed up for 2-24 (12.5±2.3) months,during which no enlargement or rupture of visceral artery aneurysms and no operation-related severe complication or death occurred.Conclusion Detachable fibered coils occlusion system combined with standard pushable coils is safe and effective for mild and moderate visceral artery aneurysms.
