Abstract
Fifty-two patients with carotid TIAs and thirteen patients with vertebrobasilar TIAs were investigated by angiography and computed tomography. TIA was diagnosed by clinical symptoms in accordance with the criteria for TIA of the Joint Committee for Stroke Facilities in the U.S.A. (1974). The 65 patients with TIAs included 49 males and 16 females with average age of 63.5 years old at the initial episode of TIA. As for the diseases associated with TIA, hypertension (51 %), diabetes mellitus (15 %) and ischemic heart diseases (11 %) were the major disorders. Atrial fibrillation was observed in 2 cases. Intervals from last TIA attack to angiography were less than 7 days in 22 cases, 8 -- 30 days in 19 cases, 1 -- 4 monthes in 14 cases and more than 4 monthes in 10 cases, respectively. The cases in which angiography was done earlier after attacks displayed more abnormal findings. In 52 patients with caroted TIAs the artherosclerotic change of extracranial portion of the internal carotid artery was found in 14 cases (27 %), that of intracranial portion of the artery in 11 cases (21 %) and both lesions in 2 cases (4 %). On the other hand, in 13 patients
