[Are problems with portosystemic shunts still a reality and is shunt selectivity the deciding factor for justifying
Objective:
The objective of the work is detailed evaluation of portosystemic shunts. The criterium of suitability and justification is their selectivity and preservation in the course of time.
Methods:
The authors used a clinical group of patients who had either a Warren shunt or a mesocaval H-shunt with a limited blood flow (diameter 8 mm). In these patients the blood flow was assessed by dopplerometry in the portal vein and before the shunt, i.e. in the lienal or possibly mesenterial vein.
Results:
Of 32 shunts made during the last five years it was possible to make 12 assessments (8 Warren and 4 H-mesocaval shunts). An adequate decline in the blood flow in the portal vein was recorded and a corresponding increase in the lienal or mesenteric vein. Even after one year no marked drop in the flow through the portal vein was recorded.
Conclusion:
A distal Warren shunt and H-mesocaval shunt with a restricted blood flow preserve the signs of selectivity even after one year. An adequate blood flow through the liver is also preserved. From this aspect selective shunts are still suitable treatment of portal hypertension. Obviously correct indication is the basic prerequisite of success.
