  • Title: Morphological study on the thebesian veins of the right cavities of the heart in the dog.
    Author: Esperança Pina JA, Correia M, O'Neill JG.
    Journal: Acta Anat (Basel); 1975; 92(2):310-20. PubMed ID: 1155019.
    Abstract:
    The authors studied 48 dog hearts, using the injection-corrosion-fluorescence method to study the topography of thebesian veins in all the walls of the cardiac cavities. The thebesian veins are small, situated deep in the myocardium, opening after a short course into the cardiac cavities, by small openings with diameters in general not exceeding 1 mm, known 'foraminula'. They have a centripetal course, while every other vein in the heart has a centrifugal one, to reach the subepicardial zone. In the heart of the dog five types of thebesian veins were served: arboriform, sinuous, brush-like, canaliculated and stellate. The thebesian veins are almost regularly found in every wall of the cardiac cavities. The authors also observed that they predominated in the right ventricle (81.24%) and in the right atrium (77.43%).
