Abstract
During the last 6 years, we performed neck clipping on 504 intracranial cerebral aneurysms at our institution. Among them 146 aneurysms were located in the middle cerebral artery. Six aneurysms arose from the origin of the lenticulostriate artery and represented 1.2% of all 504 cerebral aneurysms and 4.1% of 146 middle cerebral aneurysms. Two patients were male, and 4 were female. The age ranged from 46 to 75 years old (average; 59.8 years old). Four patients harbored multiple aneurysms (67%). All 6 aneurysms were clipped within day 3 using lateral trans-Sylvian approach. Postoperative cerebral infarction was noted on CT scan in 3 patients. We discuss the mechanism of postoperative infarction and review some relevant literature.
