Here we reported results of surgical therapy on 26 patients of multiple cerebrovascular occlusions (21 males, 5 females; average age 55).
Of the 26 cases, 13 cases had TIA'(s), 4 cases had RIND'(s) and 9 cases had minor stroke.
Multiple severe stenosis (more than 50%) and/or occlusions were found; 10 cases had bilateral internal carotid artery, 6 cases had unilateral internal carotid and vertebral artery, 3 cases had bilateral internal carotid and vertebral artery, 3 cases had bilateral middle cerebral artery, 2 cases had unilateral internal carotid and middle cerebral artery stenosis and/or occlusion, and 2 cases had, 4-vessel' occlusion.
Surgical procedures depended mainly on the patients, general condition, neurosurgical symptome, angio-graphic findings and other examinations; 14 cases had unilateral STA-MCA anastomosis, 8 cases had bila-teral STA-MCA anastomosis, 3 cases had unilateral STA-MCA anastomosis and carotid endarterectomy, and only one case had unilateral STA-MCA anastomosis and OA-PICA anastomosis.
The operative results were obtained as follows: 7 cases were excellent, 9 cases were good, 2 cases were fair, 4 cases were poor and 2cases died.
