[A modified technique for normothermic bloodless hepatic resection. Experimental and clinical studies].

On the basis of experimental study of canine normothermic total hepatic vascular blockade (NTHVB) through portal decompression by means of jugulo-splenic shunting. We proposed a critical period of the hepatic ischemic time with NTHVB be 45 minutes. The conventional technique of Heaney's bloodless hepatic resection was modified, including the cancellation of the synchronous blockade of the abdominal aorta and effective application of limited hepatic ischemic time to the critical manipulation during operation through the combination of various techniques for hepatectomy. The technique was successfully employed in 4 patients with central hepatic tumors. The modified Heaney's technique is simpler and safer than the conventional one. It may increase the resectability of central hepatic tumors (segments I, IV, V, VIII of Couinaud's classification) and is of clinical value.
