Analysis of Digital Subtraction Angiography in 126 Cases with Central Vertigo

Purpose To investigate the morphological changes of cerebral blood vessels by digital subtraction angiography (DSA) in patients with central vertigo, so as to provide references for diagnosis and treatment. Materials and Methods Total of 126 patients suffering from central vertigo were performed cerebral angiography. The types, proportion, and distribution of the cerebrovascular abnormalities were observed and analyzed. Results Of the 126 patients with central vertigo, cerebrovascular abnormalities were found in 91 cases, including 11.9% of anterior circulation abnormalities, 81% of posterior circulation abnormalities and 7.1% of both. Conclusion The posterior circulation stenosis or abnormalities might be the major reasons for central vertigo, hyperlipidemia and hypertension are the main risk factors.
