[Anatomo-surgical notes on mesenterico-caval anastomosis with interposition of a prosthesis].
On the base of 17 interposition meso-caval shunts and of 24 cadaver dissections, the Authors discuss some technical details concerning this method of portal decompression. The segment of the superior mesenteric vein more suitable has his superior limit at the mid-point of the third duodenal portion, where his diameter is already as at the converging point with the splenic vein. The length of this segment nevertheless is conditioned by the different anatomical rapports with the third duodenal portion. The insertion of the graft can be obtained either dissecting through the mesenteric root, either after mobilization of the right colon. With the last procedure resulted easir the inferior vena cava dissection, while no technical differences where encountered during the procedures with the superior mesenteric vein isolation.
