Abstract:
Objective To evaluate the safety and feasibility of Wingspan stent for patients with symptomatic M1 stenosis of middle cerebral artery (MCA). Methods Thirty-two cases with recurrent symptomatic MCA stenosis resistant to medical therapy treated by self-expanding stent were reviewed retrospectively [average (49±19) years old, 13 women]. All patients underwent angioplasty and stenting with the Gateway balloon-Wingspan stent system. After 6 months, all patients were followed up by telephone or clinic, and advised followed up with DSA or TCD. Results Thirty-two patients were successfully stented during the first treatment session. The mean degree of stenosis reduced from (76.5±15.4)% to (19.3±9.2)%. The number of complicating subarachnoid hemorrhage was one, and occlusion occurred on one patients related to balloon angioplasty. During a follow-up of 6 months, there was no recurrence of transient ischemic attack or stroke in 32 available patients. Cerebral hemodynamics using transcranial Doppler monitoring were normal in 19 follow-up patients. Six-month angiographic follow-up was obtained in 5 patients, demonstrating good patency in 5 stenting vessels. The other patients refused to perform TCD or DSA. Conclusions Wingspan stent for symptomatic stenosis of middle cerebral artery appears to be a safe and feasible under strict control of periperformeral project. However further study is needed to evaluate the long-term effect.
