Abstract

Objective: To study the relationship between congenital vertebral artery hypoplasia and clinical symptom. Methods: To analysis the clinical characteristics and features of DSA for 60 patients with vertebral artery hypoplasia which were diagonosed by DSA. Results: The position of vertebral artery hypoplasia was 42 cases on right and 19 cases on left in 60 patients.One patient was bilateral.The mean diameter of vertebral artery hypoplasia was(2.02±0.15) mm,it was much smaller than that of the normal vertebral artery(4.32±0.31) mm significantly(P0.01).Clinical symptoms were simple vertigo in 25 cases and TIA of vertebral artery system in 35 cases. Conclusion: Vertebral artery hypoplasia is the risk factor of ischemic stroke.
