Renal venous architectonics in domestic swine.
Renal venous architectonics were investigated in 240 kidneys from 120 swines at an age of 1-8 months. The methods used were: preparation, corrosion and X-ray examination. It was established that, in 75% of the cases, v. renalis cranialis and v. renalis caudalis were present. In the rest of the cases (25%), v. renalis intermedia was present. It was also observed that right and left renal veins formed distentions, which enveloped the caudal medial part of each adrenal gland. V. adrenalis (suprarenalis) was not formed as an independent blood vessel. Venous blood from the adrenal gland drains through 2-3 orifices in these distentions. This study describes vv. prelobares, vv, interlobares and vv. arcuatae. Anastomoses were found between them. On that basis this concluded that the renal venous system in domestic swine is not segmented.
