Harada et al reported a simple equation for predicting the volume of the left lobe of the liver. This can help to determine if size of the left lobe of the liver is suitable for live donor transplantation. The authors are from Kyushu University in Japan.
Patient population: adult
Outcome: volume of left lobe of liver, presumably in a Japanese population
Parameters:
(1) body weight in kilograms
(2) left-to-right thoracic distance in an AP chest X-ray (presumably at the level of the diaphragm), in cm
volume of the left lobe of the liver in mL =
= (7.7 * (body weight in kilograms)) - (12.6 * (left-to-right thoracic distance in cm)) + 313.4
Limitation:
• The equation may need to be adjusted in Caucasians and other races.
• The landmarks for the left-to-right thoracic distance need to be standardized. Variables include the precise level and the position relative to the ribs.
