Notes:
The venous system of the canine brain was investigated by gross dissection and by radiographs. The system was divided into four major groups of vessels: cerebral veins, central veins, cerebellar veins, and pontomedullary veins.The dorsal cerebral veins emptied into the dorsal sagittal sinus and the ventral cerebral veins entered the dorsal petrosal or transverse sinus. The internal system of cerebral veins, and the central veins, were drained by the great cerebral vein which entered the straight sinus. Cerebellar and pontomedullary veins flowed mainly to the sigmoid sinus.The venous system of the dog differed from the human configuration in several ways. In the dog the major dorsal cerebral veins entered the dorsal sagittal sinus by independent lacunae in the same direction as the flow of blood. A middle cerebral vein was not present in the dog but was replaced by a continuation of the caudal ventral cerebral vein. There was a basal vein in the dog but its main flow of blood was to the dorsal petrosal sinus; in man, this vein passes to the great cerebral vein. The entire venous system of the brain was plexiform and collateral circulation was prominent. The larger veins were identified radiographically.
