Název v původním jazyce

Morphology of the vasa vasorum in coronary arteries of the porcine heart

Popis výsledku v původním jazyce

Introduction: The vasa vasorum interna were described during the last decade as a special kind of vessels originating directly from the lumen of the paternal artery and participating in the nourishment of its wall, especially of the aorta and coronary arteries. At the same time, their existence was repeatedly denied/negated by many other authors. Aim: The purpose of the actual study was the anatomical verification of the existence of the vasa vasorum interna in porcine coronary arteries. Materials and Methods: The vascular supply was studied on the wall of the anterior interventricular branch of the left coronary artery on 36 hearts taken from healthy pigs. Light microscopy, vascular injections and scanning electron microscopy were used for the analysis of 141 samples. Results: In only two cases small arteries resembling vasa vasorum interna and originating directly from the lumen of the coronary artery were found. But, in both cases these vessels ran without branching, passed over the whole thickness of adventitia and branched in the wider periarterial space. In contrast to this all feeding arteries of the vasa vasorum arose from the larger branches of the paternal artery, branched entirely in its adventitia and did not enter the media. Conclusion: Due to the very low incidence of these small arteries originating from the lumen of the paternal artery and the absence of their participation on the nourishment of the arterial wall we came to the conclusion that it is not suitable to use the term "vasa vasorum interna "for their designation.
