It is well known that T. I. A will be prodromal or alarm sign of cerebral infarction. These patients with frequent T. I. A., who had STA-MCA anastomosiswere reported in the present study. The first case, a 59-year-old man presented with frequent attacks of weakness and sensory impairment of right upper extremity lasting about 30 minutes after drinking. Cerebral angiogram showed the left internal carotid artery occlusion. The second case, a 44-year-old woman developed left hemiparesis and speech disturbance on January, 1977 lasting about 5 minutes. After that, the episode occurred three times. Cerebral angiogram showed right M_1stenosis. The third case, a 38-year-old man developed sudden onset of right hemiparesis and dysarthria lasting from 10 to 15 minutes. This attack increased and became to occur two times a day. He had no attack after taking Aspirim. Cerebral angiogram showed left M_1 stenosis. These patients were free of T. I. A. in all cases since they had STA-MCA anastomosis. We discussed the prognosis of the T. I. A. and emphasized the importance of STA-MCA anastomosis in T. I. A.
