ABSTRACT
BACKGROUND:
Multilayer stent has become a new endovascular strategy for visceral artery aneurysm repair. However, its use was not allowed in some areas, such as China. This study evaluates an alternativemethod:
multiple overlapping bare stents for repairing visceral artery aneurysms.METHODS:
Twenty-four patients with celiac artery aneurysm (n = 2), splenic artery aneurysm (n = 8), hepatic artery aneurysm (n = 3), superior mesenteric artery aneurysm (n = 6), and renal artery aneurysm (n = 5) were treated with 2 to 4 overlapping bare stents. Long-term results, including clinical achievement ratio and target artery patency, were followed up with computed tomographic angiography.RESULTS:
Insertion of overlapping bare stents was successful in all patients. Five aneurysms (21%) were totally excluded 3 months after operation, increasing to 12 (50%) and 20 (83%) aneurysms with total isolation at 6 and 12 months' follow-up, respectively. The clinical achievement ratios of multiple overlapping bare stents on splenic artery aneurysms, hepatic artery aneurysms, renal artery aneurysms, celiac artery aneurysms, and superior mesenteric artery aneurysms were 75%, 100%, 80%, 50%, and 100%, respectively. All cases combined had 100% target artery patency.CONCLUSIONS:
Preliminary experience showed that repair using multiple overlapping bare stents seemed to be a potential alternative strategy for treating visceral artery aneurysm, resulting in target artery patency. However, the exact mechanism requires further study and more cases should be involved.
