Objective To summarize individualized surgical treatment strategies for complex middle cerebral artery (MCA) aneurysms.Methods Twenty patients with complex MCA aneurysms treated by microsurgery in Chinese People's Liberation Army General Hospital between December 2009 and November 2012 were retrospectively analyzed.There were 12 male and 8 female patients,with a mean age of 43 years (range:14-58 years).Giant aneurysms (size ＞ 2.5 cm) were found in 6 cases,wide-neck aneurysms in 7 cases and serpentine ones in 3 patients.Important perforators were involved in aneurysm neck in 2 cases.Important branches originated from aneurysms in 6 patients.Two patients harbored recurrent aneurysms after coiling.Individualized surgical strategies were planned according to preoperative imaging.A frontotemporal approach was routinely used.Intraoperative somatosensory evoked potential monitoring,indocyanine green videoangiography and microvascular Doppler ultrasonography were regularly used.A postoperative digital subtraction angiography (DSA) or computed tomography angiography (CTA) was performed to verify the efficacy of treatment and patency of bypass vessels.Results Of the 20 cases,7 aneurysms were clipped with clipping and reconstruction of parent artery with multiple clips,3 M1 segment aneurysms were proximally occluded with extra-intracranial high-flow revascularization,2 aneurysms were treated with aneurysmectomy with superficial temporal artery to middle cerebral artery low-flow revascularization,1 aneurysm was treated with aneurysmectomy with superficial temporal artery to middle cerebral artery lowflow revascularization and branch side-to-side anastomosis,2 aneurysms were treated with aneurysmectomy and re-anastomosis of parent artery,1 aneurysm was treated with aneurysmectomy and re-anastomosis of parent artery and reinplantation of lenticulostriate artery,3 bilateral MCA aneurysms were clipped by unilateral approach,and 1 was trapped.Nineteen patients were favorable with Glasgow Ontcome Scale score 4-5 at discharge,and 1 patient died of cardiac infarction one week after surgery.The mean clinical followup was 20 months (range:6-39 months).During follow-up,no bleeding occurred.DSA or CTA confirmed absence of aneurysm in 14 cases and residual neck in 2 patients.The other 3 patients were lost to follow-up.Conclusions Individualized,multi-modality surgical treatment strategies are effective and safe solution for treatment of complex MCA aneurysms.Revascularization remains imperative surgical technique.
