A CASE OF BASILAR ARTERY INSUFFICIENCY:LOCAUZATION OF THE LESION AND ANTICOAGULANT THERAPY

　脳底動脈循環不全症は最近我が国でも漸く臨牀方面の注目を惹く様になつたが，我々は，最近恐らく本症によると思われる種々の神経症状を呈し且つ抗凝血剤の投与により諸症状の著しい改善を見た興味ある症例を経験したので茲に報告し，併せて若干の文献よりその診断及び脳の血管障害に対する抗凝血剤療法について検討してみたい。

50year-old man complained of headache from the beginning of this disease. Successively several days later, he had onset of right spastic hemiparesis, diplopia, dysarthria, dysphagia, and retention of urine and feces. These symptoms were progressive. Examina-tion revealed paralysis of conjugate gaze to the upward and the left outward, ptosis of the right eyelid, loss of the right corneal reflex, upper motor neurone type of right facial palsy, horizontal nystagmus on gaze to the left and spontaneous nystagmus, loss of the right pharyngeal reflex, paresis of the right XI th and XII th nerve, moderate diminu-tion of deep and discriminative sensation, slight disturbance of right touch and thermal sense, hyperactive tendon reflexes and several positive pathological reflexes of the right extremities, disappearance of abdominal and cremasteric reflex, and cerebellar ataxia of the left extremities. Chocked disc, aphasia, apraxia and astereognosia were not observed. Cerebral angiogram, P. E. G. and E. E. G. were, however, normal.
