Lineal venous drainage in bovine fetuses

Abstract

A total of 30 bovine fetuses was utilized (19 males e 11 females) in order to study the lienal venous drainage. Illustrations of the vascular arrangement of the spleens, as demonstrated by the vinylite-corrosion technique, are presented. Venous drainage of the spleen stems from the cranial (cranial-para-axial branches) and caudal (caudal- para-axial branches) borders and diaphragmatic surface (short branches). These branches empty into para-axial trunk, found in all of the cases. In this study, use caudal para-axial branches were invariably longer than the cranial para-axial branches.
