Patterns of arterial vascularization in swine hearts
Abstract: This study aimed to characterize the patterns of arterial vascularization in swine hearts. Ninety swine hearts were submitted to the Spalteholz diaphanization technique in order to dissect the coronary arteries. Three types of arterial vascularization patterns were characterized through th...

Ninety swine hearts were submitted to the Spalteholz diaphanization technique in order to dissect the coronary arteries. Three types of arterial vascularization patterns were characterized through the behaviorof the rami circumflexus and interventricularis, namely: balanced, right and left types. The balanced pattern was the most frequently (42.2%); in this case, the rami circumflexus and interventricularis occupied their respective sulci. The right type (40%) was further categorized into three vascularization subtypes. In the first, ramus circumflexus dexter branched from the ramus interventricularis subsinuosus. In the second, the arteria coronaria dextra branched from ramus interventricularis subsinuosus and ramus circumflexus. In the third model, arteria coronaria sinister branched from ramus interventricularis paraconalis. The left type (17.7%) exhibited two subtypes. In the first, ramus interventricularis paraconalis ran through the entire corresponding sulcus and the ventral third of sulcus interventricularis subsinuosus, and ramus interventricularis subsinuosus occupied the dorsal and middle third of its respective sulcus. In the second, ramus interventricularis subsinuosus branched from arteria coronaria dextra and ran through the dorsal and medium thirds of its respective sulcus, and the ventral third was occupied by the collateral branch of ramus circumflexus sinister. Our results reinforce the thesis that the blood distribution system through the coronary artery in swine is similar to human, not only in qualitative but also by a quantitative comparison.http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-736X2016000500417&lng=en&tlng=enCoraçãosistema cardiovascularcirculaçãoo coronáriasuínosmodelos animais. |
