DSA analysis of 265 Patients with ischemic stroke

Objective To analyze DSA data of 265 patients with ischemic cerebrovascular disease,further evaluation the significance of DSA in the diagnosis and treatment of ischemic cerebrovascular disease.Methods 265 patients with ischemic cerebrovascular disease were performed DSA after onset 2h ～ 6 months.To clear existence of cerebral artery stenosis or occlusion,responsibility artery stenoses and measurement of stricture length and the degree of stenosis.Results The rate of cerebral artery stenosis or occlusion in 265 patients was 72.1%.Ischemic cerebrovascular disease in patients with cerebral vascular stenosis or occlusion of the predilection sites were the Ministry of the internal carotid artery(16.4%),horizontal segment of middle cerebral artery(13.9%),vertebral artery openings(12.3%).Single cerebral artery stenosis or occlusion of 88 cases(46.1%),multiple cerebral artery stenosis or occlusion of 103 cases(53.9%),including intracranial artery tandem lesions in 43 cases(41.7%),intracranial non-tandem lesions of 60 patients(58.3%).Responsibility for detection of the artery was 77%.Concluosion Those patients with recurrent stroke and diabetes should be performed DSA to clarify whether intracranial/ extracranial cerebral artery stenosis exist,and develop more effective secondary prevention including drug and stent implantation.
