MORPHOLOGICAL STUDIES ON THE BLOOD VESSELS OF THE ELBOW REGION OF THE DOG

The purpose of this study is to investigate in details the major blood vessels and their branches in the structures of the elbow joint through corrosion, radiography, and computed tomography angiography. The vessels were visualized on 17 canine thoracic limbs. The corrosion cast was obtained after the introduction of Duracryl-Plus dental plastics through the brachial artery, freezing and subsequent tissue lysis. Barium sulfate introduced through the same artery postmortem was used to visualize the vessels by radiography. For the purpose of computed tomography angiography, an arterial catheter was introduced into the brachial artery through which a contrast solution of Ultravist 300 at a rate of 0.5 ml per second was injected using an infusion apparatus. Variations in arterial anastomoses in the elbow region have been identified.
