The value of DSA in ischemic cerebrovascular disease

Objective To investigate the value of digital subtraction angiography(DSA) in diagnosis and treatment of ischemic cerebrovascular disease. Methods 325 patients with recurrent attacks transient ischemic attacks or cerebral infarction undergone DSA were reviewed and compare to MRA. Results In all cases,18No abnormality seen,163 extracalvarium arterioarctia,76 intracalvarium arterioarctia,68 exterior and interior cranium arterioarctia or obstruction. 83 undergone interventional therapy.After stent-assisted angioplasty,the stain of brain has increased and the cycle time has shorten. Conclusion DSA is gold standard in ischemic cerebrovascular disease,Compared to MRA,it can identify the region,shape, character of diseased and collateral circulation, it's the necessarily method in prevenient interventional therapy.In to evaluated the hemodynamic change of the pre-operative and the post-operative of stent-assisted angioplasty,DSA have an adventage than other exam.
