Middle Cerebral Artery (MCA) Aneurysms in Multiple Intracranial Aneurysms
Journal Title: Journal of Neurological Sciences-Turkish - Year 2006, Vol 23, Issue 3
Abstract
Intracranial saccular aneurysm is the most frequent cause of the spontaneous subarachnoid hemorrhage. At least, a second aneurysm is detected during the operation or initial angiography in about one – third of cases with subarachnoid hemorrhage. 95 consecutive patients with subarachnoid hemorrhage, were evaluated retrospectively. We detected 24 aneurysms in 11 patients . There were 4 male and 7 woman ranging in age from 23 to 70 years with mean age 54,7. Their neurological status according to Hunt and Hess scale were; 4 (% 36,3) grade I, 3 ( % 27,4) grade II and 4 (%36,3) grade III. Density of hemorrhage in the multiple aneurysm group was greater than the group of single aneurysms according to Fisher grade system. (% 72, 8) patients with multiple aneurysms were graded as grade IV according to Fisher grade system on initial CT, while only % 28,5 of patients with single aneurysm were in grade IV. Middle cerebral bifurcation aneurysm was detected as the most frequently aneurysm. The rate of MCA aneurysm (% 21,4) among all patients was significantly lower than the rate of MCA aneurysm accompanying to multiple aneurysm (% 72,7). One third of patients with MCA aneurysm were taking part in a multiple aneurysm. All patients with subarachnoid hemorrhage must be evaluated for multiple saccular aneurysms by four vessel angiography. Especially,subarachnoid hemorrhage suggesting a MCA aneurysm in the initial CT, must be carefully evaluated because clipping all detected aneurysms is the goal of therapy in patients with SAH.
