One year follow-up of the first bilateral living-donor lobar lung transplantation in Japan.

One-year follow-up results on Japan's first bilateral living-donor lobar lung transplantation concern a 24-year-old woman who had become ventilator-dependent due to severe bronchiectasis associated with primary ciliary dyskinesia. Surgery was conducted using her sister's right lower lobe and her mother's left lower lobe. Total forced vital capacity of the 2 transplanted lobes was 51.7% of the recipient's predicted forced vital capacity. One-year after transplantation, her forced vital capacity was 2,160 ml--73.2% of her predicted forced vital capacity. The recipient's sister's decrease in forced vital capacity was 410 ml and that of her mother 440 ml. The recipient and donors have since returned to normal, unrestricted lives.
