Objective..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 of patients with central vertigo. Methods： Ninety-two patients suffering from central vertigo were subjected to cerebral angiography through femoral artery. The types, proportion, and distribution （site predilection and number of involved vessels） of the cerebrovascular abnormalities were observed and analyzed. Results： Of the 92 patients with central vertigo, cerebrovascular lesions were found in 137 sides, including 15 （10.95 % ） anterior circulation lesions and 122 （89.05% ） posterior circulation lesions. Thirty-one （ 33.7 % ） patients had 2 or more lesions. The most common lesion was vertibroarterial lesion accompanied with other cerebrovascular stenosis. The lesions included 39 （28.47 %） sides with vertibro-basilar stenosis or occlusion, 13 （9.49 %） sides with posterior cerebral artery stenosis or occlusion, and 59 （43. 06%） sides with posterior circulation abnormalities. Conclusion： The posterior eireulatlon stenoses or abnormalities might be the major reasons for central vertigo in middle- and old-age patients.[
