[Topographical and radiological correlations in aneurysms of the middle cerebral artery]

The authors demonstrated topographic-radiological correlations in cases of middle cerebral artery aneurysms verified surgically. In an own material of 91 cases treated in the Department of Neurosurgery, Medical Academy in Cracow in the years 1980-1983 the relationship of the aneurysm to the neighbouring vessels and the direction of the dome of the aneurysm were analysed. In the presented material aneurysms of the middle cerebral artery accounted for 18% of all intracranial aneurysms. Most frequently they were situated at the main bifurcation of the artery (86.8%). The dome of the aneurysms of the main bifurcation was lying usually in the line prolonging the main trunk of the artery cephalad and laterally. The results of surgical treatment are presented in 81 patients with aneurysms of the middle cerebral artery treated surgically.
