The authors report 11 cases who underwent reoperations upon for recurrent aneurysms. The initial operations were performed on average 10.1 years earlier for subarachnoid hemorrhage (SAH). The patients' mean age at the first surgery was 39.7 years. The locations were 9 internal carotid (IC)-posterior communicating artery (PC) and 2 anterior communicating artery (A-com) aneurysms. A residual aneurysmal neck after the first operation was observed in 3 of 10 cases confirmed by postoperative angiography. The primitive-type PC artery was seen in 8 of 9 recurrent IC-PC aneurysms. The recurrent manifestations were SAH in 9 cases. Clipping operations were conducted in 10 and ligation of the IC artery together with extracranial-intracranial bypass in 1 large IC-PC aneurysm. The present study demonstrated two risk factors for aneurysm recurrence, namely, young age and IC-PC aneurysms with a primitive-type PC. Furthermore, direct operation for recurrent aneurysm is often embarrassing due to adhesions to the surrounding tissue as a sequela of the previous operation, hence understanding of the anatomical correlation between the old clip and the recurrent portion is important.
