Functional features of blood and cerebrospinal fluid circulation through the dura venous sinuses depend on anastomotic connections with intracranial and extracranial venous systems. The spatial and structural organisation of the dog’s sinuses is not well understood, especially the sinuses of the skull base. Three main types of blood outflow have been identified in mammals, which means that each type has its own mechanism and conditions for the development of pathological processes of blood supply to the dog brain. Our results can also be considered as an experimental model of scientific research. The work aimed to establish the macroscopic morphological features of the dog cavernous sinus. To achieve this goal, we used corrosion preparations of the venous bed of helpless dogs. The models were scanned, and their 3-D images were obtained, which made it possible to establish comprehensive morphometric parameters. We used an approximation method followed by statistical analysis of the data. The corrosive preparations showed that the cavernous sinus in dogs is represented by right and left longitudinal canals, which are rostrally anastomosed to the ophthalmic veins. The latter, in turn, are directed to the orbit, where they flow into the orbital venous plexus. Around the sella turcica, the right and left canals are connected by intercavitary anastomoses - rostral and caudal, which may be absent. The free posterior divisions of the cavernous sinus diverge laterally and, heading into the posterior cranial fossa, pass into the ventral petrosal sinus, located in the petrous-occipital bone canal. The preparations show a complex of emissary veins, through which blood flows to the veins of the head and the internal jugular vein. Thus, the dog cavernous sinus is macroscopically represented by three sections on corrosion preparations: 1 - rostral, anastomosing with the ophthalmic veins, 2 - central, located near the sella turcica together with the anterior and posterior intercavernous sinuses, and 3 - caudal, passing into the ventral petrosal sinus. At the end of the morphological study of the dog’s cavernous sinus, we performed a comprehensive morphometric analysis of each section’s length, width and height. We determined the area of the ring around the pituitary stalk. The results obtained after statistical processing are presented in tables for certain groups of animals.
