Abstract

We studied the arterials and venous distribution of 30 pairs of four months old Large White breed pig's kidneys (15 females and 15 males) from the Matadouro e Frigorífico "Eder", in Itapecerica da Serra, SP. After fixing the material in water solution of formol at 10.0% we dissected the vascular elements of the renal pedicle. In these animals the right renal artery supplies from six(10.0%) to twenty (3.3%) branches, generally with ten(20.0%) and the left from four (3.3%) to eighteen (3.3%) showing a greater indice of ten (16.7%). The greatest concentration being on the craniodorsal quadrant, following the cranioventral, caudoventral and caudodorsal quadrants. Concerning the venous roots, the right renal vein shows a variation from one(10.0%) to five (33.8%) roots, generally with five(33.8%) and left from two (13.3%) to seven (3.3%) with greater concentration of (26.7%) localized with greater frequency in the cranioventral quadrant followed by the caudoventral, craniodorsal and caudodorsal quadrants. Referring to the general situation, of the alone mentioned, the branches of the right and left arteries appear a greater number of times on the outer side (43.3%) while the venous root shows exclusively on the outer side (16.7%). There is an equal number of renal arteries and veins branches, right and left, once (3.3%) with a unequal distribution in the quadrants. There is no significant statistic difference between sexes.
