Aims: Intraoperative blood loss (IBL) usually predominates during the dissection of the native liver. A right-lobe living donor liver transplantation (LDLT) sometimes requires an additional procedure to obtain an autologous vein from the recipient for the vascular reconstruction. These procedure can sometime contribute to progressive coagulopathy causing unexpected bleeding. Therefore, we analyzed our cases to determine the optimal timing for vascular preparation from the patient in terms of IBL. Methods: Among 67 patients included in the study, 30 did not require an additional procedure to obtain the venous graft (group A), and 37 LDLT employed a superficial femoral vein (SFV). Of these, 13 had undergone removal of SFV after the hilar dissection and liver mobilization from retrohepatic area while preserving the inferior vena cava (group B), and 24 removal of the SFV immediately after hilar dissection without liver mobilization from the retrohepatic space (group C). Results: A significant difference existed only in the scores of the Model for End-stage Liver Disease. Although the median IBL for group C was similar to that for group A, the median IBL for group B was significantly higher than that for other 2 groups. The median duration from skin incision to graft implantation for group B was significantly longer than that for groups A and group C, because of the additional hemostatic procedures in the retrohepatic space including the leg site. Conclusions: The timing for removal of SFV in LDLT patients affects IBL associated with consumptive coagulopathy and prolongs operative time. Based on our experience, we concluded that SFV preparation should be performed before liver mobilization from the retrohepatic area to minimize IBL.
