Background |
The aim of this study was to delineate an algorithm for donor and recipient criteria and middle hepatic vein (MHV) management in right-graft live-donor liver transplantation (LDLT) on the basis of computerized 3-dimensional computed tomographic image analysis.
Methods |
Data on 94 consecutive right-graft LDLTs were prospectively collected. Graft and remnant data for the first 23 cases were retrospectively evaluated by means of 3-dimensional computed tomographic reconstructions, and on the basis of that preliminary series, a graft selection algorithm using 3 parameters—hepatic vein dominance classification, graft and remnant graft volume/body weight ratios, and congestion volumes—was created. It was subsequently applied to the next 71 right-graft LDLTs.
Results |
Fifty-nine right grafts contained the MHV. Four of the 12 grafts with no MHVs required MHV reconstructions. In 18 cases, small liver grafts were used. The postoperative function of liver grafts and remnants with versus without MHVs was not statistically different.
Conclusions |
The proposed algorithm favored the inclusion of the MHV with the right grafts. It also allowed for the procurement of grafts that were potentially small for size without compromising donor or recipient safety.
