A contribution to the study of arterial and venous vascularization of the kidney hilus in German Shepherd dogs

Abstract

In this paper we studied the number, distribution, the entry and exit sites of arterial branches and venous roots in 30 pairs of kidneys obtained from 15 male and 15 female German Shepherddogs. The paper was done not only to improve our knowledge of the kidney morphology but also to bring some data to comparative anatomy. The kidneys were dissected, at least 48 hours, after being fixed in a 10% formalin solution. Concerning the right kidney the arterial branches numbered 7 to 14 were localized in the craniodorsal and cranioventral quadrants while the venous roots numbered from 3 to 5 predominated in the cranioventral and caudoventral quadrants. Most of the vessels showed peripheral situation. In relation to the left kidney the arterial branches numbered from 8 to 15 were seen in the craniodorsal quadrant and the venous roots numbered 2 to 4 in the caudoventral quadrant. We found an exclusive peripherical situation for the arterial branches and venous roots in almost all kidneys examined.
