Value evaluation of digital subtraction angiography in diagnosis of ischemic cerebrovascular diseases

Objective To evaluate the diagnostic value of digital subtraction angiography to ischemic cerebrovascular diseases. Methods 52 patients with ischemic cerebrovascular diseases were performed with cerebrovascular angiography by DSA on the aortic arch, brain matter and some main vessel branches. Results Cerebral infarction were 43 cases. DSA revealed that 6 were normal and 37 were abnormal with 53 pathological changes in all, 1.23 pathological changes each patient. There were 8 cases with transient ischemic attack, of which 3 cases revealed with DSA were normal and 5 were abnormal. 1 case had transient complete amnesia and his DSA wasn't normal. Conclusion DSA may confirm the kinds of pathological changes, judge the prognosis, and offer evidences for endovascular intervention treatment of cerebral artery stenosis.
