Haemodynamic changes in the cerebral circulation of the cat during occlusion of the middle cerebral artery

In a group of 21 cats, the middle cerebral artery pressure (MCAP) was recorded by means of a catheter introduced into the artery at its origin, just distal to the occlusion. The effects of hypertension, hypercapnia, and hypocapnia were studied. In a group of five cats, both middle cerebral arteries (MCA) were catheterized and the pressure was...
