[Hepatic surgery with vascular exclusion. Experimental bases. Technic and preliminary results]

Hepatic surgery has a high mortality due to hemorrhage or gas embolism due to tears of the hepatic veins or vena cava, hence the idea of temporary vascular exclusion. Based on clinical, hemodynamic, laboratory and pathological findings, we have designed a catheter which permits one to isolate the retro and suprahepatic segment of the vena cana and obtain hepatic vascular exclusion within 30 minutes. We report here six cases where this technic was used, 3 hepatectomies, 2 liver injuries, and one case of disobstruction of an iliac vein which confirm the use, ease and harmlessness of this method.
