Referrals for lung transplantation in Japan. Unique indications and necessity of living-donor lobar lung transplantation.

Abstract

The purpose of this study was to review all referrals to our lung transplant program and to find realistic options for accepted candidates in Japan. During the period from April 1992 to August 1999, 45 referrals were received. After screening, 22 of the referred patients were admitted for an extensive inpatient evaluation, and 15 of these were accepted as candidates for transplantation. The indication was primary pulmonary hypertension in 9, bronchiectasis in 2, lymphangioleiomyomatosis in 2, idiopathic pulmonary fibrosis in 1, and pneumoconiosis in the other 1. Two of those with primary pulmonary hypertension went to the USA and there received bilateral lung transplant. One with bronchiectasis received living-donor lobar lung transplantation in our center. These three recipients are alive and doing well during the follow-up period of 11 to 69 months. Among the 12 patients who have not received lung transplant, 5 patients have died while waiting. Indications for lung transplant are quite distinct in Japan, and primary pulmonary hypertension is the most frequent indication. Living-donor lobar lung transplantation is a realistic option for properly selected candidates.
