Rebleeding after stenting and coil embolization of an aneurysm in anterior wall of the internal carotid artery

Objective: To report a case of early rebleeding of an arterial wall wide-necked aneurysm of the internal carotid artery with stenting and coil embolization. Methods: Balloon-expandable stent was deployed across the aneurismal neck through endovascular approach. Microcatheter was superselectively introduced into the aneurismal sac for coil packing. Results: The procedure was technically successful with stent completely covering the neck and 90% occlusion by coil packing of the aneurysm; simultaneously keeping the patency of parent artery and adjacent perforating arteries. The patient recovered well, but died fur rerupture and rebleeding of the treated aneurysm on the 16th day after the procedure. Conclusions: Endovascular stenting combined with coil embolization is an alternative method for treating anterior wall wide- necked aneurysm of the internal carotid artery, but attention and recognition of the risk of early rebleeding of the treated aneurysms should always be kept on mind therefore short-term follow-up and prompt treatment are critically necessary.
