Origem e ramificações ventriculares da artéria coronária esquerda no macaco prego (Cebus apella)

Abstract

Was to study the origins and ramifications, ventricular branches and of the left coronary artery. 25 monkey used taken from Cebus apella (Capuchin monkey), 12 male and 13 female. by means of injection of neoprene latex 601 A® (Du pont do Brasil S/A) colored with Suvinil color 2350 0003®), through the right femoral artery and hereafter dissection. The left coronary artery originated from the coronary ascending aorta, covering the coronary groove and driving on the left in 21 animals (84%), and of this total, 19 animals (90.5%) coronary artery left in the forked branches paraconal interventricular and left circumflex in 2 cases (9.5%), there was a trifurcation of the left coronary artery trunk, the branches, paraconal interventricular, left circumflex and a headset to face the left ventricle. In 4 cases (16%), interventricular branch and circumflex paraconal left originated from the left coronary sinus via separate ostia. The following were anastomoses between the branches and sinuous paraconal interventricular and circumflex branches between the left and right.
