Portal flow steal after liver transplantation
نویسندگان
چکیده
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.

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 venous perfusion steal causing graft dysfunction after orthotopic liver transplantation: serial imaging findings in a successfully treated patient
A 53-year-old male with hepatocellular carcinoma underwent orthotopic liver transplantation. Preoperative computed tomography revealed main portal vein luminal narrowing by flat thrombi and the development of cavernous transformation. On post-transplantation day 1, thrombotic portal venous occlusion occurred, and emergency thrombectomy was performed. Subsequent Doppler ultrasonography and contr...
متن کاملLigation of huge spontaneous porto-systemic collaterals to avoid portal inflow steal in adult living donor liver transplantation: A case-report
INTRODUCTION In adult living donor liver transplantation (LDLT), maintenance of adequate portal inflow is essential for the graft regeneration. Portal inflow steal (PFS) may occur due to presence of huge spontaneous porto-systemic collaterals. A surgical procedure to increase the portal inflow is rarely necessary in adult LDLT. PRESENTATION A 52 years male patient with end-stage liver disease...
متن کاملPerioperative management of spontaneous splenorenal shunts in orthotopic liver transplant patients.
OBJECTIVES Spontaneous splenorenal shunts cause significant vascular steal from the liver. There is no accepted algorithm for treating spontaneous splenorenal shunts before, during, or after liver transplant, and evidence for efficacy of treatments remains limited. MATERIALS AND METHODS We reviewed the literature, and our institution's experience regarding spontaneous splenorenal shunts, incl...
متن کاملA Case of Left Renal Vein Ligation in a Patient with Solitary Left Kidney Undergoing Liver Transplantation to Control Splenorenal Shunt and Improve Portal Venous Flow
BACKGROUND Adequate portal venous flow is required for successful liver transplantation. Reduced venous flow and blood flow 'steal' by collateral vessels are a concern, and when there is a prominent splenorenal shunt present, ligation of the left renal vein has been recommended to improve portal venous blood flow. CASE REPORT A 51-year-old man who had undergone right nephrectomy in childhood re...
