When severe stenosis or occlusion develops in a surgically inaccessible segment of the internal carotid artery or in the middle cerebral artery, what collateral flow possibilities exist to maintain cerebral function? How does a microneurosurgical superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis contribute to preexisting collateral blood flow? Detailed descriptions of possible collateral pathways surrounding high cervical and cerebral arterial occlusions have been previously made.(1–5,7,9–11) It is our purpose to describe and illustrate the frequency of these collaterals in 26 anastomosis patients, and to give a radiologic evaluation of the contribution of these anastomoses to collateral flow.
