Mesentericocaval shunt with the internal jugular vein.
Seventy-nine mesocaval shunts using the internal jugular vein and 54 side-to-side portocaval shunts have been performed during the past six years. Patients were evaluated from the stand-point of protection from recurrent bleeding, patency of the shunt, encephalopathy, rehabilitation and long term survival. All of the patients underwent follow-up observation. In a selected group of patients, postoperative angiographic control was performed, and serum levels of octopamine were examined. In the mesentericocaval group, patency of the shunt was demonstrated in 82 per cent, the incidence of encephalopathy was 35 per cent and the long term survival rate, as computed by the actuarial method, was 65 per cent. In the portocaval group, the incidence of encephalopathy was 54 per cent and the survival rate, 38 per cent. There was no correlation between octopamine serum levels and encephalopathy. Persistent perfusion of the liver was documented in 95 per cent of the patents controlled by arteriography in the mesentericocaval group with patent shunts. The mesentericocaval shunt seems to be an effective technique in terms of incidence of encephalopathy and survival rate, but a randomized study will be necessary to prove that this technique is more effective than the standard portocaval shunt.
