ARTERIAL COLLATERAL CIRCULATION OF THE BRAIN


Abstract
The collateral circulation to the brain exists in 3 main areas: (1) through extracranial arterial connections; (2) through developmental extracranial to intracranial persisting arteries; ,and (3) through intracranial cerebral arterial anastomoses. The intracranial cerebral arterial collaterals occur in 3 main areas: (1) through connections of the large base vessels (circulus arteriosus cerebri); (2) through connections between the perforating vessels directed to the basal cell masses; and (3) through interarterial connections on the suprasegmental areas of the brain. All functional collateralization occurs on the surface of the brain.
