We report a case of a ruptured aneurysm originating from the posterior wall of the left internal carotid artery (ICA) that was treated with multi-clipping and radial artery graft (RAG) bypass. A 41-year-old man developed sudden-onset headache, followed by generalized convulsion. The initial computed tomography (CT) scan revealed subarachnoid hemorrhage (SAH), and CT angiogram (CTA) revealed aneurysmal dilatation of the posterior wall of the left ICA. Rebleeding near the lesion suggested a blood blister-like aneurysm causing SAH. On day 2, we performed an operation to insert multiclips to obliterate most of the lesion. The postoperative course was uneventful. Ischemic complications, rebleeding, or regrowth of the aneurysm was not observed for 1 year postoperatively.
