Abstract:
Objective To explore the efficacy and safety of endovascular therapy in the treatment of symptomatic M1 stenosis of middle cerebral artery as well as the causes of perioperative complications.Methods Two hundred fifty-six patients with symptomatic M1 stenosis of middle cerebral artery (＞90％) confirmed by TCD,cerebral CT angiography and DSA was treated by endovascular intervention.The success rate,the changes of stenosis,longterm vascular patency rate,in-stent restenosis rate were analyzed.Results endovascular stent was successfully placed in 251 patients with the M1 part of symptomatic middle cerebral artery stenosis and the successful rate was 98.05％.Fifteen patients had complications (5.86％) which caused neurology deficits and deaths.The degree of vascular stenosis was significantly reduced after stenosis (Before vs After:92.26％±2.11％ vs 15.40％±2.60％).The mean mRS and NIHSS scores was decreased significantly.The average follow-up duration was (21.70±0.80) months,249 patients underwent a second DSA and the mean stenosis was (21.70％±0.80％).Twenty-three patients developed instent restenosis (ISR) and ISR rate was 9.24％.Recurrence ischemic stroke and transient ischemic attacks occurred in 5 patients and recurrence rate was 2.01％.Conclusion Endovascular therapy of symptomatic M1 stenosis of middle cerebral artery is safety and efficacy with low complications.The follow-up results reveal good patency rate and excellent prevention of anterior circulation ischemia.
