[Portal circulation following the Warren operation--computerized tomography study of portal hemodynamics 5 to 11 years following distal splenorenal anastomosis]

Abstract

18 patients underwent CT-investigation with bolus injection of contrast medium 5 to 11 years after splenorenal Warren shunt. According to this investigation all patients were found to have developed hepatofugal collaterals in consequence of distal splenorenal anastomotic suction. In most cases the portal liver perfusion was maintained. These effects are not homogeneous and show variations from patient to patient.
