A. prostatica branches to most of the organs, situated in the pelvic cavity. The prostate is vascularized by three large blood vessels; the cranial ramus is the smallest one, the medium ramus is the main vessel of the gland, and the caudal one is divided into three little rami before reaching the prostate. Because of the multiple ramifications of a. prostatica (NAV, 1994) we condsider more appropriate to call it a.pelviana. A. prostatica is suitable name of its final part, giving three ramifications: a. prostatica cranialis, a. prostatica media, a. prostatica caudalis.
Blood draining vessels are not always accompanying the arterial ones. We found out several routes of draining blood from prostate, specified to different glandular regions. On the ventral surface, two veins are formed: v. prostatica ventralis caudalis and v. prostatica ventralis cranialis. In the middle part of the gland there are two other veins. The main vessel draining blood from the gland is situated laterally to the prostatic lobes in the middle of each lobe (v. prostatica). The other vessel is situated on the medial side in the middle of each lobe (v. prostatica medialis). V. prostatica is the only satellite vessel. It is situated in the vicinity of a. prostatica media. For the precise classification, v. prostatica should be changed for v. pelviana. The name v. prostatica should be attributed to its final part.
