Vertebrobasilar Insufficiency Surgical Treatment And Experimental Study

Study design:. A retrospective research of diagnosis and treatment of 102 cases patients with no trauma vertebrobasilar artery insufficiency.Objective:To find a standard classing no trauma vertebrobasilar artery insufficiency based on digital subtraction angiography for better clinical outcome. Methods: 102 cases patients, diagnosed by digital subtraction angiography and symptoms as vertebrobasilar artery insufficiency, were classed four types based on digital subtraction angiography. Patients received treatment according to the type they belonged to.Results: 102 cases were classed as four types: 1 the type of vertebral artery being pressed, 2 the type involving sympathetic nerve, 3 the type of the occlusion located I and IV segment of vertebral artery, 4 congenital abnormality and atherosclerosis. 45 cases accepted treatment of no surgery, 11 cases accepted the treatment of intrusion, and 46 cases accepted operative treatment. Of all cases, outcome of 65 (63.7% ) cases is excellent, 25 (24.5%) cases is good, and 12(11.7%) cases is no good. Conclusions: Operative decompression is proper for patients, whose imagination of vertebral artery were pressed directly .To the type involving sympathetic nerve caused by instability of cervical spine, internal fixation and fusion is good choice. For the type of the occlusion located I and IV segment of vertebral artery , the treatment of intrusion were chosen. Standard classing no trauma vertebrobasilar artery insufficiency based on digital subtraction angiography is instructive for treatment for...
