Results of endovascular treatment of middle cerebral artery aneurysms after first giving consideration to clipping.

Abstract：

BACKGROUND:Middle cerebral artery (MCA) aneurysms are among the more challenging aneurysms for endovascular treatment. We report a contemporary 5-year experience with endovascular therapy for MCA aneurysms at a high-volume neurovascular center. METHODS:Review of prospectively maintained intracranial aneurysm database. RESULTS:Between 2005 and 2009, 148 patients underwent treatment of 149 MCA aneurysms at our hospital, of which 33 patients with 34 aneurysms underwent endovascular therapy. Among these 33 patients, 14 presented with subarachnoid hemorrhage. Eleven patients were treated with stent-assisted coiling, 1 with balloon-assisted coiling, and the remainder with coiling alone. Three patients required repeat endovascular treatment. There were 7 periprocedural complications, including intraprocedural aneurysm rupture resulting in death in 2 patients. Two patients died at later dates from remote aneurysm rehemorrhage. Average follow-up of remaining patients was 17.1 months radiographically, and 20.3 months clinically. Average modified Rankin scale (mRS) score at last follow up was 2.09, with 17 patients with mRS 0/1 and 5 patients with mRS 2. Fifteen patients showed evidence of radiographic residual at last follow up: 13 were simple neck residuals. Unruptured status and saccular aneurysms were associated with mRS 0/1 outcome (each p < 0.05). CONCLUSIONS:At our hospital, MCA aneurysms are being treated with endovascular techniques, but in a minority of patients. Despite the rate of residual neck remnants, few retreatments were necessary and few rehemorrhages occurred. The periprocedural complication rate was not insignificant; therefore, in more recent years and at present, most MCA aneurysms are considered for clipping first at our center.
