Risk of venous congestion in live donors of extended right liver graft

Table 2 Concordant vs non-concordant interrelation between remnant volume (donor) body weight ratio and remnant volume percentage of total liver volume in discriminating small-for-size from non-small-for-size remnants according to two different cut-off values

¹incl. 2 remnants with RVBWR = 0.60;

²incl. 1 remnant with RVBWR = 0.60. SFS: Small-for-size; RV/TLV: Remnant volume percentage of total liver volume; RVBWR: Remnant volume (donor) body weight ratio.
