Integration of hepatic vein tributaries with a diameter 5 mm into the drainage system in rightlobe
living-donor liver transplantation (LDLT) is of vital importance for graft function.
Recently, the most commonly emphasized hepatic venous reconstruction model is the all-in-one
reconstruction model. In the final stage of this model that aims to form a common large opening,
allogeneic vascular grafts are almost always used to construct a circumferential fence. To date,
no other study has reported the use of polyethylene terephthalate (Dacron) vascular graft as a
circumferential fence in LDLT. We aimed to present the 1st 4 cases of circumferential fences
created with Dacron vascular graft. Four right-lobe grafts weighing 522e1,040 g were used. A
polytetrafluoroethylene vascular graft was used for the integration of segment 5 vein and
segment 8 vein into the drainage model, whereas a Dacron graft was used to creating a
circumferential fence. The patency of hepatic outflow evaluated with the use of multidetector
computerized tomography at postoperative day 7. Venous outflow obstruction
was not detected in any cases. This study suggested that owing to its flexible structure the
polyethylene terephthalate vascular graft can be an alternative to allogeneic vascular
grafts in forming circumferential fence.
