Abstract
Hepatic encephalopathy due to portosystemic shunts is a well-defined entity in patients with cirrhosis. Rarely, liver transplant recipients develop hepatic encephalopathy owing to persistence or surgically created portosystemic shunts. We present a case of post-transplant recurrent hepatic encephalopathy due to a surgically created portocaval shunt. The patient was managed by a covered metal stent placement in the inferior vena cava, thus causing functional closure of the shunt.

Unusual venous collateral pathways allow for reperfusion of the intrahepatic portal venous system in children with portal vein thrombosis after split liver transplantation: Clinical relevance and management implications.

Abstract
PVT is the most frequent vascular complication after LT in small children, and a higher incidence has been observed in those transplanted for biliary atresia or with a LLSG. Thrombosis of the PV causes extrahepatic portal hypertension and is associated with splenomegaly and the development of venous neo-collaterals, including gastro-oesophageal varices and splenorenal shunts. It has also been incidentally suggested in the literature that patients who have had a Roux-en-Y loop for a biliary reconstruction may present with a cavernomatous transformation of the distal portion of the loop. In this study, 13 children with CEPH caused by thrombosis of the PV after LT were analysed. The study evidenced the development of two types of hepatopetal venous networks: (a) a large cavernoma along the Roux loop and around the biliary anastomosis, and (b) a network of neo-collaterals in the gastro-duodeno-pancreatic area that connected to the intrahepatic portal branches directly through the liver capsule. These hepatopetal venous networks between the venous system of the surrounding organs or the omentum and the intrahepatic portal branches can be identified by radiologists. The relevance for the transplanting physician and the transplant surgeon is discussed.

Abstract
Postshunt hepatic encephalopathy after liver transplantation (LT) is an infrequent condition and is commonly associated with portal occlusion or stenosis and the presence of a patent portosystemic shunt. Portal vein stenosis (PVS) or thrombosis (PVT) are uncommon complications after LT. The overall frequency of both complications is reported to be less than 3%. When PVS or PVT develop early after LT, the occlusion of the portal vein can have catastrophic consequences to the graft including acute liver failure and graft loss. Late PVT/PVS are asymptomatic in approximately 50% of the cases and mainly diagnosed by a routine ultrasound. Symptomatic postshunt hepatic encephalopathy (HE) is a very infrequent condition after LT that has been scarcely reported in the literature. We present here the case of a liver recipient with normal graft function who presented with hepatic encephalopathy 3 months after LT with stable liver function but a severe portal stenosis and the presence of a spontaneous portosystemic shunt whose successful endovascular treatment was followed by the complete resolution of the HE.

Abstract
Direct portal revascularization can be achieved by interposing a vascular graft between the SMV and the Rex recessus (left portal vein system): the MRB. To review indications and results of the procedure in the setting of pediatric liver transplantation, reports were selected from the English literature. Previously reported series were updated to analyze long-term outcome. A new series was added and analyzed as a complementary set of cases. A total of 51 cases were analyzed. With a 96% overall patient survival rate and a 100% long-term patency rate when the IJV is used for the bypass, MRB achieves a very successful physiologic cure of chronic portal hypertension and restores the portal flow into and through the liver graft. It also has been used successfully for primary revascularization of liver grafts, as well as for managing early acute portal vein thrombosis episodes. The use of this procedure in conjunction with other strategies and techniques might be of interest for transplant surgeons, particularly those caring for children.

Abstract
PHALT may result from graft dysfunction, portal vein thrombosis, arterio-venous fistulas and can lead to GIB, commonly from bleeding esophageal varices. We present three children with GIB requiring multiple blood transfusions that were diagnosed with RY Loop bleeding. Routine EGD, colonoscopy, and CE failed to reveal the bleeding source. However, enteroscopy revealed large varices at the site of hepaticojejunostomy anastomosis in all. Our experience demonstrates that RY loop varices in children with PHALT are a rare and treatable cause of obscure GI bleeding.

Abstract
A 20-year-old patient underwent liver transplantation (LT) because of chronic hepatitis-associated cirrhosis. After transplantation, the patient developed partial portal vein thrombosis without deterioration of liver function. However, in the long-term follow-up, the patient developed refractory portal hypertension with recurrent episodes of severe upper gastrointestinal bleeding. Extensive nonoperative treatment including multiple esophageal ligatures and sclerotherapy was not successful. Thus, the patient had to be treated surgically with a mesocaval H-shunt. Pathophysiology, therapy and prognosis of this rare complication after LT are discussed with regard to the literature.
