BACKGROUND & AIMS: Complex portal vein thrombosis (PVT) is a challenge in liver transplantation (LT). Extra-anatomical approaches to portal revascularization, including renoportal (RPA), left gastric vein (LGA), pericholedochal vein (PCA), and cavoportal (CPA) anastomoses, have been described in case reports and series. The RP4LT Collaborative was created to record cases of alternative portal revascularization performed for complex PVT. METHODS: An international, observational web registry was launched in 2020...

BACKGROUND: This study was designed to analyze the risk of extra-anatomical portal vein reconstruction during liver transplantation (LT) in patient with portal vein thrombosis (PVT). METHODS: Patients who underwent LT between 2008 and 2018 were reviewed. PVT was graded according to the Yerdel system. Risk factor for portal vein complication-free, graft and overall survival were analyzed with multivariate Cox regression. RESULTS: Seventy out of 1180 patients had PVT...

BACKGROUND AND PURPOSE: Small infants with biliary atresia and hypoplastic portal veins (PV) are at risk for portal vein thrombosis (PVT) after liver transplantation (LT), which can lead to graft loss and mortality. Extra-anatomical PV reconstruction techniques have been established for adult cases of PVT; however, they have not been widely accepted for infants. METHODS: Here, we report the successful use of an extra-anatomical meso-portal venous jump graft to treat early PVT after LT in a 6-month-old infant with biliary atresia and PV hypoplasia...

Although the lateral segment (LS) from the split-liver of a deceased donor or a live donor can increase the organ pool of pediatric patients awaiting liver transplantation, the shortage of organ donation in Asia countries is still serious and results in high death rates of pediatric patients. The medial segment (MS) of the liver is sacrificed during the standard technique of splitting a whole liver into an LS and an extended right liver because the cutting sites of portal vein, hepatic artery and bile duct are all in the bifurcation of the liver hilum to have adequate length of vascular and biliary pedicles for easier grafting...

BACKGROUND: Portal venous and hepatic arterial reconstruction are critical to successful outcomes in orthotopic liver transplantation (OLT). With portal vein thrombosis or inadequate hepatic arterial inflow, extra-anatomic vascular reconstruction is required. However, the clinical outcomes following extra-anatomic vascular reconstruction are largely unknown. METHODS: To determine the outcomes associated with extra-anatomic vascular reconstruction, we performed a retrospective review of 205 OLT recipients transplanted between 1995 and 2000...

Portal venous thrombosis in hepatic transplant candidates is considered a relative contraindication to transplantation. In addition to thrombectomy, which is often technically impossible, donor portal venous arterialization or extra-anatomic venous bypass have been described. Two patients who underwent portal venous resection and subsequent anatomic reconstruction are presented herein. In the first patient, a graft with donor common iliac vein was interposed, and in the second, the donor portal vein was long enough to be anastomosed to the mesentericosplenic venous confluens...

Splanchnic venous inflow is considered mandatory to ensure graft survival after liver transplantation. Over a 68-month period, we performed 570 liver transplants in 495 patients. Portal vein thrombosis was present in 16 patients. At transplant, the extent of the occlusion included portal vein alone (n = 4), portal including confluence of the splenic and superior mesenteric veins (n = 8), portal, splenic, and distal superior mesenteric veins (n = 2), and the entire portal vein, splenic vein, and superior mesenteric vein (n = 2)...
