Endovascular stenting for symptomatic stenosis of middle cerebral artery / 介入放射学杂志

ABSTRACT

Objective To summarize the early experience and results of endovascular stenting for symptomatic stenosis of middle cerebral artery. Methods We performed percutaneous endovascular stent assisted angioplasty in 20 patients with symptomatic high grade stenosis of MCA, who had either recurrent transient ischemic attacks (TIAs) resistant to medical therapy or perfusion problems. After stenting, the patients was administrated with antiplatelet drug and followed up with DSA、TCD and SPECT. Results Stent placement and angioplasty were successfully performed in all patients except one with MCA rupture during the procedure. The mean degree of stenosis reduced from (78.3?4.7)% to (15.6?4.4)%, and the degree of residual stenosis were less than 30%. None of these patients developed TIAs or stroke during the follow up period. Angiography revealed no evidence of restenosis. TCD and SPECT suggested significant improvement of cerebral perfusion. Conclusions Endovascular stenting for MCA stenosis seems to be a safe and effective therapeutic method. Further study is needed for long term outcome.
