换一批摘要Objective:To describe the clinical fea-tures of a case of ischemic stroke caused by pseudo severe stenosis of vertebral artery(VA).Methods:The clinical history and image data of a 52-year-old man with ischemic stroke were collected.Results:Computerized tomography angiography(CTA)revealed stenosis of V1 and V4 of the left VA.DSA confirmed that the anterior blood flow recov-ered after stent implantation,and the V4 segment of the left VA was normal without stenosis.Conclusions:It is spec-ulated that the upper stenosis is due to local hemodynamic changes rather than real stenosis.This case suggests that the interpretation of stenosis on CTA should consider cere-bral vascular anatomy and hemodynamic changes.
