ABSTRACT

Delayed appearance of the anterior cerebral arteries on an isotopic cerebral flow study in association with a right frontal area of decreased activity was seen in a patient with a hemorrhage from a ruptured anterior communicating artery aneurysm. It is suggested that closer scrutiny of the major vessels, in addition to the usual grosser hemispheric observations, would prove this finding to be more frequent. The importance of making this observation of delayed appearance of a major vessel, particularly in conjunction with a hemispheric abnormality, is that it raises the suspicion of an aneurysm as the cause of the cerebral vascular accident. This suspicion alters the further evaluation and care of the typical stroke patient because a lesion potentially correctable by surgery may otherwise be overlooked.
