The significance for the cerebral blood supply of anastomoses between the branches of the external and internal carotid arteries

  • A. M. Blinova

A study was made of the blood supply to the brain and the extracranial, tissues in hypoxia, hypercapnia and during stimulation of the intestinal interoceptors; measurements were made before and after occluding the anastomoses. The blood flow was recorded on a photokymograph. Simultaneous recordings were made, by a thermoelectric method, of the blood flow in the meninges and anterior carotid arteries, and of the arterial pressure and respiration. The results have shown: a) That occlusion of the anastomoses does not affect the cerebral blood supply, and b) that in reflex reactions of the general circulation, the nature and extent of the changes in blood flow in the extra- and intracranial vessels were nearly the same whether the anastomoses were intact or occluded. Even when there was a backflow of blood in the extra- and intracranial vessels, occlusion of the anastomoses had but little effect upon the cerebral blood supply.
