中文摘要：

Complex internal carotid artery (ICA) aneurysms include intracavemous,paraclinoid large/giant,dissecting and blood-blister aneurysms.Proximal parent artery occlusion (PAO) and trapping are long-practiced safe and effective option for these complex aneurysms.1 Trapping refers to both proximal and distal occlusion of parent artery including aneurysms,which is considered more reliable than proximal PAO due to without reverse flow.We hereby describe a rare case of subarachnoid hemorrhage (SAH)after trapping ICA to treat complex ICA aneurysms.The report was approved by the Ethics Committee of our institute and written informed consent was obtained from the patient.
