1.What is vertebral artery stenting? The procedure is basically the same as internal carotid artery stenting, and no umbrella is usually placed during the procedure. Stenting is the first choice for vertebrobasilar artery stenosis. By placing a stent, the ischemic symptoms of the vertebral artery can be significantly improved and the incidence of cerebral infarction can be reduced. 2.Who is treated by vertebral artery stenting? ①Asymptomatic vertebral artery stenosis with vascular diameter stenosis >70% or symptomatic (TIA or stroke attack) with vascular diameter stenosis >50%. (ii) Those with <50% stenosis, but with ulcerative plaque formation or a coarctation aneurysm. (iii) For patients with symptomatic bilateral high stenosis. ④Patients with occlusion or dysplasia of the contralateral vertebral artery. 3.What are the advantages of vertebral artery stenting? Stenting is the first choice for the treatment of vertebrobasilar stenosis. By placing a stent, the ischemic symptoms of the vertebral artery can be significantly improved and the incidence of cerebral infarction can be reduced. Arterial stenting is less traumatic and has fewer complications than surgery, and can be performed under local anesthesia, resulting in less pain and fewer days in the hospital, fewer cardiovascular complications, and better stroke reduction.
