Abstract
The anatomic surgical arterial segmentation of the kidney in wild boar (Sus scrofa). Thirty pairs of kidneys of wild boar (Sus scrofa) were studied from adult males, with permission from the Brazilian Institute of theEnvironment (Process n. 02001.003237/05), aiming to characterize the vasculature and anatomic surgical segmentation. The arteries of these kidneys were injected with red pigment and subsequently submitted to acid corrosion in order to identify the renal arterial vascular pattern, particularly its divisions and distribution. The results reveal the sectorial branches of the renal arteries, two in number (cranial and caudal); the sectorial arteries provide the segmentary branches to the dorsal and ventral portions of the kidney; in the right kidney, the segmentary branches are 2-6 in the cranial sector and 3-7 in the caudal sector. In the right kidney, the segmentary branches are 3-7 and 2-7 in the same respective sectors; the vascular arterial symmetry (25%) between the right
and left kidney in the animals is evident. There are 3 arterial anatomic surgical segments on both kidneys. On the basis of the distribution of the sectorial and segmentary arteries, it is possible to accomplish setorectomy and segmentectomy on the kidneys of the wild boar, with functional aspects such as species preservation and animal experimental modeling.
