The anatomosurgical arterial segments of the kidney of mongrel caprines

ABSTRACT

Thirty pair of kidneys of adult, mongrel caprines, Capra hircus, were studied after injection of a plasticsubstance followed by corrosion, focusing on the main branches of the terminal divison of the renal artery and their distribution through renal sectors. Segmental arteries and consequently anatomicosurgical segments were identified. The right and left renal aa, were always single and bifurcated into ventral and dorsal sectorial arteries, which in turn originate, off the segmental arteries. Extra-hilar arteries were foundin the right kidney 20 (per cent) and left 10 (per cent) and were also considered segmental arteries. More frequently there were 4 anatomosurgical segments in the ventral sector being 53 (per cent) on the right and 66.7 (per cent) on the left, and in left kidney, eight anatomosurgical segments ventrocranial, ventromediocranial, and ventrocaudal, in the ventral sector, and dorsocranial, dorsomediocranial, dorsomediocaudal and dorsocaudal, in the dorsal sector. Bilateral symmetry of the renal arterial anatomosurgical segmentation occured in 20 (per cent).
