“…However, we often encounter GRWR mismatch in donors in clinical practice. In the case of difficult graft selection, the right posterior sector (RPS) graft is an alternative for liver graft to ensure the safety of the donor and overcome these problems ( 15 - 17 ). Currently, RPS transplantation is mainly carried out in Asian countries, especially Japan and South Korea.…”

Background: The anatomy of the right posterior portal vein (RPPV) plays an important role in planning hepatic resection, living transplantation and interventional radiological procedures, yet the incidence of variations of RPPV without a common trunk in Chinese persons is still unclear. Therefore, we conducted this study and discussed its clinical implications.Methods: A retrospective analysis of multidetector computed tomography (MDCT) scans was performed

“…Another favorable anatomy is an extrahepatic right posterior HD that drains into the common HD. Additionally, the right posterior HD that runs through the ventral side of the right posterior PV is the most suitable anatomy [ 11 , 12 ].…”

Purpose Unusual grafts, including extended left liver plus caudate lobe, right anterior section, and right posterior section grafts, are alternatives to left and right lobe grafts for living-donor liver transplantation. This study aimed to investigate unusual grafts from the perspectives of recipients and donors. Methods From 2016 to 2021, 497 patients received living-donor liver transplantation at Severance Hospital. Among them, 10 patients received unusual grafts. Three patients received extended left liver plus caudate lobe grafts, two patients received right anterior section grafts, and five patients received right posterior section grafts. Liver volumetrics and anatomy were analyzed for all recipients and donors. We collected data on laboratory examinations (alanine aminotransferase, total bilirubin, international normalized ratio), imaging studies, graft survival, and complications. A 1:2 ratio propensity-score matching method was used to reduce selection bias and balance variables between the unusual and conventional graft groups. Results The median of Model for End-stage Liver Disease score of unusual graft recipients was 13.5 (interquartile range 11.5–19.3) and that of graft–recipient weight ratio was 0.767 (0.7–0.9). ABO incompatibility was observed in four cases. The alanine aminotransferase level, total bilirubin level, and international normalized ratio decreased in both recipients and donors. Unusual and conventional grafts had similar survival rates (p = 0.492). The right and left subgroups did not differ from each counter-conventional subgroup (p = 0.339 and p = 0.695, respectively). The incidence of major complications was not significantly different between unusual and conventional graft recipients (p = 0.513). Wound seromas were reported by unusual graft donors; the complication ratio was similar to that in conventional graft donors (p = 0.169). Conclusion Although unusual grafts require a complex indication, they may show feasible surgical outcomes for recipients with an acceptable donor complication.

“…Additionally, the right posterior HD that runs through the ventral side of the right posterior PV is the most suitable anatomy. [11,12] Donor Graft Sectionectomy Division of ligamentum teres to hilar dissection was performed in the same manner as that for right anterior section grafts. The posterior branches of the right HA and PV were identi ed and isolated separately.…”

We collected data on laboratory examinations (alanine aminotransferase, total bilirubin, international normalized ratio), imaging studies, graft survival, and complications. A 1:2 ratio propensity score matching method was used to reduce selection bias and balance variables between the unusual and conventional graft groups. Results: The mean model for end-stage liver disease score of unusual graft recipients was 18±9.64 and mean graft recipient weight ratio was 0.80±0.18. ABO incompatibility was observed in four cases. The alanine aminotransferase level, total bilirubin level, and international normalized ratio decreased in both recipients and donors. Unusual and conventional grafts had similar survival rates (p=0.492). The right and left subgroups did not differ from each counter-conventional sub-group (p=0.339 and p=0.695, respectively). The incidence of major complications was not significantly different between unusual and conventional graft recipients (p=0.513). Wound seromas were reported by unusual graft donors; the complication ratio was similar to that in conventional graft donors (p=0.169). Conclusion: Although unusual grafts require a complex indication, they may show feasible surgical outcomes for recipients with a donor safety.
