[Experimental study of portal and caval clamping in dogs. Its significance in the direction of vascular exclusion technics of the liver in men]. / Etude expérimentale des clampages cave et porte chez le chien. Son intérêt dans l'orientation des techniques d'exclusion vasculaire du foie chez l'homme

An experimental study of portal and inferior vena-caval clamping in the dog showed the respective roles of splanchnic blood sequestration and inferior vena-caval blood sequestration in the onset of the hemo-dynamic disturbances caused by vascular exclusion of the liver, with severe arterial hypotension. Stasis in the inferior vena cava is corrected by a caval shunt which, on the other hand, has no effect on splanchnic stasis. Clamping of the aorta may, however, act on both components of the hypotension, and this has proved promising.
