ABSTRACT
<p><b>OBJECTIVE</b>To summarize individualized surgical treatment strategies for complex middle cerebral artery (MCA) aneurysms.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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 low-flow 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 Outcome Scale score 4-5 at discharge, and 1 patient died of cardiac infarction one week after surgery. The mean clinical follow-up 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.</p><p><b>CONCLUSIONS</b>Individualized, multi-modality surgical treatment strategies are effective and safe solution for treatment of complex MCA aneurysms. Revascularization remains imperative surgical technique.</p>
