[Morphologic study of the arterial vasa vasorum of the pulmonary veins in dogs].
The authors studied 54 hearts of dog, to try and find a pattern of the origin, traject and distribution of the vasa vasorum of the great vessels in the heart of the dog. They used the injection-corrosion-fluorescence method imagined by one of them, verifying the good penetrability of the substance they injected and a fine visualization under Wood light. They observed that the arterial vasa vasorum of the pulmonary veins come from the atrial branches of the circumflex artery, from an atrial antero-right branch of the artery of sinusatrial node, branches from the right-coronary artery and from the bronchial arteries. The systematize the arterial blood supply of the different sides of the pulmonary veins, though it is not a rigid classification as the atrial arterial branches, supplying the vasa vasorum, show a great variability of size and there are several anastomosis between them.
