Pulmonary function of individual lung lobes after complex living-donor lobar lung transplantation using inspiratory and expiratory three-dimensional computed tomographic volumetry.

A combination of inspiratory and expiratory three-dimensional computed tomographic volumetry provides useful information on pulmonary function and lung volume. We previously reported an early outcome of a patient undergoing living-donor lobar lung transplantation with sparing of the bilateral native upper lobes. Long-term follow-up on such patients had not been reported, and therefore we herein, for the first time, reported the 2-year follow-up of the previously reported case. According to the inspiratory and expiratory three-dimensional computed tomographic volumetric data, we demonstrated that transplanted lower lobe grafts had been working efficiently and spared bilateral native upper lobes had not provided any adverse effects.
