TIAおよびminor strokeに対するSTA-MCA吻合術:(20症例の経験から)

概要

論文の詳細を見る
During the past 5 years, we have performed STA-MCA anastomosis (superficial temporal artery-middle cerebral artery anastomosis) for 20 cases of TIA and minor stroke, while, we admitted about 300 cases of ischemic cerebrovascular accident in the same period.<BR>Eleven cases of them were started by TIA in which 5 cases of them revealed stenosis or stricture of the internal carotid artery and 6 others had the stricture of middle cerebral artery, all at the trifurcation on carotid angiography. 3 cases of internal carotid occlusion were all in the age of fortieth and showed the collateral circulation via ophthalmic artery from the external carotid artery into the intracranial internal carotid artery on CAG. One of them revealed occlusion of bilateral internal carotid artery and therefore, had STA-MCA anastomosis bilaterally.<BR>Nine cases of minor stroke were identified to be caused by moya-moya disease in 4 cases, by the occlusion of middle cerebral artery in 4 cases and the rest by the stricture of internal carotid artery. All 20 cases had STA-MCA anastomosis, in 3 cases bilaterally and were followed up for 5 years in the longest case. The patency of the anastomosis was proved in 17 cases.<BR>In the follow-up study, no one had further attack any more postoperatively in the TIA group. In the group of minor stroke, two of them recovered to social life and 4 others returned to independent home life.
