説明

The contrast medium was injected to 51 cases of postmortem and studies were made by soft X ray in regard with the correlation of small and finer arteries, stenosis of middle sized artery in cerebral blood vessels, pathological and clinical evidences especially transient cerebral ischemic lesion.<br>1) Of cases with disturbance of cranial nerve function, stenosis seen on small and finer arteries was striking and in some cases with transient cerebral ischmic attack, the same finding appeared more strikingly, and also, the close correlation with progression of stenosis seen in vertebral as well as in basilar artery was observed.<br>2) When observed symptoms shown on the angiogram of cerebral arteries by soft X ray, in cases that clinical disturbance of cranial nerve function were apparent, tortuous vessels were seen numerically not only on small and middle sized cerebral arteries, but also on the entire end arteries and in cases, proliferation of blood vessels, displacement of cortical artery and medullar artery were significant.<br>3) Also, in cases with small blood vessel occlusion, diminishing number of blood vessels seen on the angiogram was marked distal to the occlusion, where a massive softening was recognized. It was noted also that stems of blood vessels were constructed as a substitute for colateral artery, by the occurance of medullar artery occlusion.<br>4) In cases with clinical neurological lesion, small cerebral blood vessels were rarely seen on the angiogram and progression of capillary blood vessels were not observed.<br>5) In cases with cerebral thrombosis, the injection media was partially diffused and some cases showed round and spotty leakage of the injection media. From these results, it is supposed that, there must be some change in permeability of blood vessel wall.. So far, it is concluded that the clinical findings of various nervous and neurotic symptoms have a close intercommunication with stenosis of small and middle arterial blood vessels and further, with the displacement of the involved end arteries as well as the abnormal change of blood vessel wall.
