The term "cerebral vascular lesions" in this report includes cerebral arteriosclerosis and cerebral apoplexy. The cerebral arteriosclerosis is not only the cause of various cerebral symptoms, but important as the basis of cerebral vascular accidents. The cerebral arteriography is an excellent method for the diagnosis of cerebral atherosclerosis as well as for the etiologic and differential diagnosis of cerebral stroke. There have hitherto been many angiographic studies of cerebral stroke, but few attentions have been paid to the angiographic study of cerebral atherosclerosis. The author has performed arteriography on 60 cases of the aged with cerebral vascular lesions, the results of which are reported here. Method 1. The arteriography and observation of eyegrounds were performed on 60 cases, and mesurement of cerebral circulation on 24 cases, with cerebral vascular lesions, aging 50 to 80. 2. The arteriography was performed transcutaneously, using 60% Urographin or 50% Hypaque as contrast medium. The patients were injected with 40% papaverinum hydrochloricum for safety 30 minutes before arteriography. For the prevention of complications, general anesthesia was applied using thiopental sodium. In each arteriography, 10cc. of Urografin or Hypaque was used. 3. The cerebral circulation was measured by the N_2O-method of Kety & Schmidt. 4. The observation of eyegrounds was made according to the Keith-Wagener classification. Results A. Cerebral arteriosclerosis The arteriographic grades of sclerosis, classified according chiefly to Brobeil and Riischede, were compared to retinal vascular changes, subjective symptoms, and cerebral hemodynamics values. 1. A rough relation was found between retinal findings (KW) and the grade of arteriographic sclerosis. 2. There was a tendency for the subjective symptoms, such as headache, drumming in the ear, and vertigo to increase with the arteriographic grade of sclerosis. 3. The comparison of cerebral circulation to arteriographic grade of sclerosis and retinal findings (KW) is as follows :
