PULSE PRESSURE CONTOURS IN CEREBRAL ARTERIES

Abstract

Pulse contours were recorded simultaneously from the lingual, the omocervical, the vertebral artery and from 1 cerebral artery in the dog. The cerebral arteries studied were the internal carotid where it enters the dura, the basilar, the middle cerebral, the posterior cerebral, the posterior communicating, the anterior cerebral and the ethmoidal. The pulse entering through the vertebral arteries may be smoothed out in the basilar so that large shifts of pressure are avoided while at the anterior portion of the circle the pulse is transferred almost unchanged to the middle cerebral artery and is not damped appreciably until it reaches the ethmoidal arteries.
