Outcomes of Microsurgical Clipping in Middle Cerebral Artery Aneurysms

Objective: Surgical or endovascular treatment is used in the treatment of intracranial aneurysms. Recent studies have suggested that the of endovascular treatment are superior to surgery Middle cerebral artery (MCA) aneurysm is the third most common bleeding aneurysm after anterior communicating artery and internal carotid artery aneurysms. We aimed to retrospectively evaluate the microsurgical outcomes of cases operated for MCA aneurysm.Methods: Twenty cases with MCA aneurysm who accepted the microsurgical treatment option were included in this study. Data were obtained by retrospectively reviewing the clinical, radiological, and intraoperative findings, as well as postoperative morbidity and mortality of the cases.Results: In total, 23 MCA aneurysms were detected in 20 cases. In 2 cases, MCA aneurysm was detected incidentally. Microsurgical clipping was performed in 23 aneurysms. In the study, the total mortality rate was 10% and the morbidity rate was 20% in MCA aneurysms.Conclusion: It was observed that the incidence of calcification or thrombosis within the aneurysm increased and the Glasgow outcome scores at the 3rd month decreased as the width and length values of the aneurysm sac increased. In addition, presence of calcification in the aneurysm wall or thrombosis in the sac was found to be positive and strongly correlated with mortality and morbidity.
