Endovascular repair of common iliac artery aneurysms with modified branched stent grafts

Objective To present our initial experience with modified branched stent grafts in endovacular repair of common iliac artery aneurysms. Methods In 5 patients, 3 were aortobiiliac aneurysms and 2 were single common iliac aneurysms, receiving endovascular repair by a novel modified branched stent graft to keep at least one internal iliac artery patency. Results All cases were successfully completed with patent external and internal iliac artery on the target side. There were no inhospital mortality nor major complications after graft stenting. During a follow-up period of 27.6 months (21 to 33 months), there have been no stenting related endoleak and branch occlusion. Conclusions Modified branched stent graft is safe and efficient, providing an effective way to protect internal iliac artery in endovascular treatment of common iliac aneurysms.
