Abstract
The right lateral sector is an alternative graft for living donor liver transplantation. Three-dimensional image reconstruction of right lateral sector grafts was performed to reveal vascular anatomy and volume using three-dimensional computed tomography software in three donors. There was a correlation between actual and estimated volume ( r = .93), although actual graft volume tended to be larger than the preoperative estimated volume. In one donor, a portal branch of the right lateral sector was independently ramified. The branch was sacrificed in the operation because its territory volume was only 44 cm 3. Three-dimensional images matched the shape of the right lateral sector graft. Three-dimensional computed tomography might be useful before donor hepatectomy, providing important information for decisions regarding the operative procedure.
