The article presented retrospective evaluation of experience for one-single site of the factors affecting the risk of perforator stroke after basilar artery angioplasty and/or stenting.A total of 255 patients were included in the study, and the decision to perform endovascular treatment as well as the stent type were made based on arterial access and lesion morphology.For those with tortuous access and mori b or c lesions or if the diameters of the proximal and distal segments were significantly different, angioplasty plus a self-expanding stent (subject balloon plus stent system) was preferred.For patients with tortuous arterial access with a mori a lesion or a small target vessel diameter (<2.5 mm), angioplasty alone with a subject balloon was selected.Procedure-related perforator stroke was identified in 13 patients (5.1%).Except for perforator stroke some patients had some other complications.Patient#8 (table2): this patient was mori type c.It was reported that the patient had dissection after the subject balloon dilation and unable to get stent through the lesion during procedure.If severe dissection or elastic recoil occurred after dilation, a balloon-mounted stent (for lesions with less tortuous access) or stent (for lesions with severe tortuous access or small target vessel) could be implanted.And about 11 hours after procedure, the patient had perforator stroke with symptoms of left extremities and face weakness and numbness, dysphagia.
