ANATOMIC STUDY OF THE DIAGONAL ARTERIES IN HEARTS OF PIGS

SUMMARY: Considering the importance of the diagonal artery for myocardial vascularization and the existence of a series of similar features between the hearts of men and pigs, this reserch was carried out to make a morphometric study of the diagonal artery in hearts of pigs. For this study 100 heart...

For this study 100 hearts of pigs were used. Coronary arteries of these hearts were injected with 15% gelatin solution stained with red chess. Next, the hearts were fixed in 10% formol solution for 10 days and dissectd to allow visualization of the diagonal artery and measurement of the ventricular height. It was considered diagonal artery only the vessel emerging from the angle between the anterior interventricular and circunflex arteries. It was observed that the diagonal artery in the hearts of pigs was present in 20% of the samples. Its lenght varied from 11,33 mm to 39,5 mm, with mean of 22,4 mm, being the majority (95%) described as artery of short course on the subepidardial plane. As for its behaviour, it was noted that it gave rise to a single branch in 50% of the cases, two branches in 45% of the cases and in one case (5%) it gave rise to three brances. It can be concluded that in case of absence of the diagonal artery the circunflex artery gives rise to many branches, possibly to play the role of irrigation suplly of the left ventricle.info:eu-repo/semantics/openAccessSociedad Chilena de AnatomíaRevista chilena de anatomía v.17 n.1 19991999-01-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0716-98681999000100011en10.4067/S0716-98681999000100011
