GONZALEZ GONZALEZ, Justo L et al. Factors affecting the results of the surgical treatment of aneurysms of the middle cerebral artery (“Hermanos Ameijeiras” hospital in the period 1983 to 2004). Rev Cubana Cir [online]. 2007, vol.46, n.3. ISSN 0034-7493.

Aneurysms of the middle cerebral artery are responsible for 20 % of aneurysmal subarachnoid hemorrhages and at the same time, this vessel is the second most common site of intracranial aneurysm formation. This article analyzed the surgical outcomes in 53 patients suffering from aneurysms in this artery. The patients aged 20 to 60 years-old were operated on at “Hermanos Ameijeiras” hospital in the period from 1984 to 2004. Good results were achieved in 69,8 % of patients whereas 7,6 % and 22,6 % of them had slight and serious sequelae respectively on discharge. No death was found in this series. It was observed that results were heavily dependent on the pre-operative state of the patient assessed according to the World Federation of Neurosurgical Societies scale: 82,7 % of those with good surgical results had been admitted at grade I of the scale but 75 % with severe sequelae had presented with grade III. The complications had also a significant impact on the results on discharge, mainly brain infarct with the worst prognosis (p = 0,0008)
