Postprocedural MR diffusion-weighted abnormalities after elective intracanial angioplasty and stenting with the Gateway balloon-Wingspan stent system

Purpose: To evalute postprocedural MR diffusion-weighted abnormalities after elective intracanial angioplasty and stenting with the Gateway balloon-Wingspan stent system (Boston Scientific), the first self-expanding stent system designed for the treatment of intracranial atheromatous disease. Methods: Thirty-two consecutive patients (11 female, mean age 64 years) with 32 symptomatic intracranial atheromatous lesions (>70%) underwent intracranial angioplasty and stenting. Ppostprocedural MR diffusion-weighted imaging was performed on 26 patients within 72 hours of the procedure. Treated vessel was the distal vert…
