Abstract:

Objective To assess the performance of the Wingspan stent system and Gateway percutaneoustransluminal angioplasty balloon catheter in the treatment of Chinese patients with symptomaticintracranial stenosis.Methods A total of 10 patients received angioplasty and stenting with the Gateway balloon-Wingspan stent system. Their lesion type, disease sites, and the rate of success for stent andprocedure were prospectively tracked for 30 days.Results The lesions sites were: middle cerebral artery (n=6), internal carotid artery (n=4),vertebrobasilar artery (n=2). The stent successful rate was 91.7% (11/12) and procedure successfulrate was 90.0% (9/10). The degree of stenosis was reduced from a baseline of 71.4% to 33.3%after angioplasty and 20% after stenting. During the 30-day follow-up, one patient had an episodeof transient ischemic attack (TIA) after the procedure. There were no periprocedural neurologicalcomplications in other 9 patients.Conclusion Angioplasty and stenting with the Gateway balloon-Wingspan stent system arefeasible and effective for treating symptomatic intracranial artery stenosis in Chinese patients. Thelong term outcome still needs to be investigated further.
