ABSTRACT
The mesenteric lymph drainage has great importance in the survival of the whole organism because it participates in the absorption of the digestive products, in the enterosystemic circulation of endogenous metabolites, and of the white blood cells. Lymphography proved to be the better method when it is done via a little laparotomy by mesenteric lymph node injection: the contrast medium flows into the inferior vena cava only in patent anastomoses. The acute and chronic obstruction of the lymph vessels has been realized experimentally in legs, but at the mesenteric level it was very difficult to induce in large animals because of the thickness of the mesenteric root and the high number of lymph vessels. In the mesenteric area, the lymphostasis can be treated by two surgical procedures: the lymph node-venous shunts and the lymphangiovenous shunts. The blood parameters reached near-to-normal values in the patent lymphaticovenous shunts.
