Portal Steal Syndrome After Full-Size Deceased Donor Liver Transplantation.
Successful liver transplantation typically results in an immediate decrease in intrahepatic resistance accompanied by an initial increased hepatopedal portal flow. Within a short period of time, the portal hypertension resolves and the variceal shunts involute. However, in situations in which intrahepatic vascular resistance to venous flow remains elevated, significant hepatofugal portal flow m...
متن کاملPortal flow steal after liver transplantation
Portal flow steal occasionally persists even after the liver transplantation, which may reduce the portal flow and thus threaten the patients' outcome. Therefore, pre- and peri-operative detection of portal steal phenomenon requiring radiological or surgical interruption is essential for the liver transplantation candidates as well as for the recipients.
متن کاملLiver graft-to-recipient spleen size ratio as a novel predictor of portal hyperperfusion syndrome in living donor liver transplantation.
Portal hyperperfusion in a small-size liver graft is one cause of posttransplant graft dysfunction. We retrospectively analyzed the potential risk factors predicting the development of portal hyperperfusion in 43 adult living donor liver transplantation recipients. The following were evaluated: age, body weight, native liver disease, spleen size, graft size, graft-to-recipient weight ratio (GRW...
متن کاملLiver transplantation as ultimate tool to treat portal hypertension.
Portal hypertension is a complication of liver cirrhosis that may itself cause complications such as variceal bleeding, ascites and hepatorenal syndrome. There are several options for symptomatic treatment including drug therapy, endoscopy, transjugular intrahepatic portosystemic shunt (TIPS), and various surgical procedures, notably liver transplantation, the only causal treatment. The indicat...
متن کاملDe novo hypertension after liver transplantation.
Hypertension develops in most patients after transplantation when immunosuppression is based on cyclosporine and prednisone. The pathogenesis appears to be multifactorial but involves rapidly rising vasoconstrictor tone in renal and systemic vascular beds. Much of this tone reflects abnormal vascular function, characterized by impaired prostacyclin and EDRF effects, in conjunction with increase...
