Results of surgical treatment of patients with aneurysms of the middle cerebral artery

Abstract

Introduction: Aneurysms of the middle cerebral artery are usually responsible for intracranial bleeding and constitute a frequent location of aneurysms. Its close arterial and venous relationship in the Silvian cistern is accompanied by high complexity. Surgical clipping is highly effective. Objective: To describe the surgical results of middle cerebral artery aneurysms operated using microsurgical clipping. Method: A descriptive, prospective study was carried out that included 50 patients from the Hermanos Ameijeiras Hospital operated on for cerebral aneurysm of the middle cerebral artery using microsurgical clipping. A pterional and minipterional craniotomy and clipping of the aneurysm were performed. The variables studied were: clinical, cerebral aneurysm and postoperative with greater importance related to complications and the Glasgow Coma Scale for results. For data analysis, absolute and relative frequencies were used as summary measures. Results: There was a predominance of unruptured aneurysms (66.0%) of large size (42.0%) and located in the bifurcation of the middle cerebral artery (94.0%). Minipterional craniotomy was used in 74.0%. In relation to the main complications, vasospasm (8.0%), hydrocephalus (6.0%) and cerebral infarction (4.0%) were reported. According to the Glasgow Coma Scale for results, there was a greater presence of grade 5 (78.0%). Conclusions: Microsurgical clipping in patients with middle cerebral artery aneurysms is accompanied by total clipping and few postoperative complications.
