Purpose : One of the most critical huddle in pediatric lung transplantation is a shortage of the size-matched donor. Lobar lung transplantation utilizing a lobe from an adult is a practical solution. Lung volumes can be measured from the chest CT by using the three-dimensional image analyzing software. However, donor chest CT is rarely available, and an accurate method to predict the size of the lobe of the adult donor using demographic data is mandatory.

Methods : A total of 100 children (2-120 months) and 162 adults (21-49 years) were enrolled. The volume of the lungs and lobes were calculated by 3D-image analysis software using Chest CT with DICOM format. We set up an equation to predict the volume of the lobes using clinical data and tested its accuracy.

Results : The volume of the lung in children (right: 119.5ml-1101.0ml, left: 102.9ml-912.8ml) and that of lower lobes in adult (right: 200.5ml~726.2ml, left: 117.4ml~577.8ml) overlapped. The equation predicting lobe volume showed an acceptable performance.

Conclusion : The selection of adult cadaveric donor for lobar transplantation can be facilitated by using a 3D-image analyzing software and the equation predicting lower lobes volumes
