Split liver transplantation: Current developments

Table 1 Recently published formulae to calculate the liver volume

Ref.	Formula	Patient group	Technique
Urata et al[20], 1995	LV (mL) = 706.2 × BSA (m2) + 2.4	96 patients (65 pediatric)	CT
Vauthey et al[21], 2002	Based on BSA:	292 adults	CT
	LV = -794.41 + 1267.28 × BSA (m2)
	r2 = 0.46; P < 0.0001
	Based on patient weight:
	LV = 191.80 + 18.51 × body weight (kg)
	r2 = 0.49; P < 0.0001
Heinemann et al[17], 1999	LV (mL) = 1072.8 × BSA (m2) - 345.7	1332 patients	Autopsy
Kokudo et al[19], 2015	LV = 203.3 - (3.61 × age) + [58.7 × thoracic width (cm)] - [463.7 × race (1 = Asian, 0 = Caucasian)]	180 Japanese and 160 Swiss patients	CT
Herden et al[18], 2013	Children 0 to ≤ 1 yr:	388 pediatrics	Autopsy
	LV (mL) = 143.062973 + 4.274603051 × body length (cm) + 14.78817631 × body weight (kg)
	Children > 1 yr to < 16 yr:
	LV (mL) = 20.2472281 + 3.339056437 × body length (cm) + 13.11312561 × body weight (kg)
