Summary

The prostate is the dog´s most important accessory sex gland, located in the pelvic canal, retroperitoneal and flow to the bladder, completely wrapping the pelvic urethra on its way out of the bladder neck. Its function is to produce seminal fluid that provides an optimum environment for the survival and motility. It may be affected by a number of pathological processes such as benign prostatic hyperplasia and neoplasia. The aim of this study was to describe the distribution of extraglandular arterial blood vessels of the canine prostate, as a factor of importance and relevance to the understanding of physiological control and certain pathological processes of the gland for subsequent medical and surgical approach. Five adult no breed male dogs between 3 and 5 years old, weighing 15 to 20 kg with no diagnosed prostatic disease, were used. They were euthanized in private and public veterinary clinics. The animals were perfused through the common carotid artery with fixative-preservative solution, and were injected by the same route after 72 hours, with red colored latex keeping the bodies in refrigeration until regional dissection. In relation with some authors, it was determined that independent of the ramifications of the prostatic artery, it always irrigates the gland through three vascular branches.
