Preoperative estimation of right lateral sector graft by three-dimensional computed tomography

Transplant Proc. 2006 Jun;38(5):1400-3. doi: 10.1016/j.transproceed.2006.02.133.

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 cm3. 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.
