title: Interposition grafting for portal hypertension.
abstract: During the past six years, thirty-seven patients underwent interposition graft shunting for thirty-three instances of bleeding from varices and five instances of intractable ascites, either electively (twenty-seven instances) or as an emergency (eleven instances). Autogenous jugular vein was used in twenty-five instances, homologous vena cava in nine, and Dacron in four. Portacaval and mesocaval anastomoses were done in equal numbers (nineteen). Using Childs' method of clinical evaluation, thirty-three patients were Class C and four Class B. There were five (13.2 per cent) early deaths with one (3.5 per cent) in the elective and four (36 per cent) in the emergency group. Twelve grafts were open at autopsy, fifteen at splenoportography, and seven assumed patent because patients were asymptomatic. Two Dacron grafts and two homografts thrombosed. There were ten late deaths, only one related to graft failure. Apparently, the operation controls ascites, with autogenous jugular vein being the ideal material. Interposition grafting is a simple, safe procedure that can be used for portal decompression in patients with bleeding varices.
