Symptomatic Intracranial Tractology

Abstract

It is well known that blood from arteries combined with various intracranial injuries shunts blood from arteries into veins. However, it is generally believed that clinical symptoms are caused by the lesion itself, rather than the redistribution of regional cerebral blood flow (rCBF). The author reports on the cerebral angiography and rCBF studies of 3 patients. Their symptoms were hemodynamic blood stealing within one cerebral hemisphere, between hemispheres, and from the brain into the tumor. Example 1: Paroxysmal right hemiplegia and aphasia, which basically recovered in about a week, but thereafter there was paroxysmal aphasia every time he hyperventilated. Technetium-99 brain scan showed increased absorption in the left parietal area, and spikes appeared in the same area on the EEG. Wave and slow wave lesions, left internal carotid artery angiography confirmed small arteriovenous malformations in the parietal lobe, the arterial blood supply mainly came from a single large branch of the middle cerebral artery, and also received from the left anterior cerebral artery and other middle cerebral arteries. Branched blood flow. The CBF results were measured using the xenon 133 method in the carotid artery, the area close to the arteriovenous malformation and forehead
