The aim of the present study is to investigate the main arterial and venous vessels responsible for the blood supply of the spleen in dogs. The vessels were visualized through corrosion cast and radiographic imaging in 5 mixed breed dogs. For the purposes of the corrosion cast two polymers were used – Biodur (Biodur Products GmbH, Germany) and Duracril-Plus (SpofaDental, Kerr Corporation, USA) introduced through the splenic artery and vein. The radiographic images were taken after injection of barium sulfas solution in a. lienalis. The main external and intramural vessels were established together with their branches in the parenchyma and the stroma of the dogs´ spleen.
