TECHNIQUES AND RESULTS IN BILATERAL SEQUENTIAL SINGLE-LUNG TRANSPLANTATION

Lung transplantation continues to evolve as a therapeutic option for patients with end-stage lung disease. Bilateral sequential single lung transplantation (BSSLTx) is a recent addition to the lung transplant surgeon's armamentarium that incorporates the benefits of single lung transplantation in patients who require double lung replacement while avoiding the morbidity inherent in the en bloc double lung transplant procedure. Between November 1992 and October 1993, 17 recipients underwent 18 bilateral BSSLTx procedures for a variety of indications. In 53% of patients, the procedure was completed without the requirement for cardiopulmonary bypass. Telescoping of the bronchial anastomosis has proved satisfactory. Induction cytolytic therapy has not been utilized. Patients received methyl prednisolone from day 1 and as maintenance prednisolone therapy. Actuarial 1-year survival is 87%; 12 of the 15 survivors are in Functional Class I. BSSLTx is an evolving transplant option for patients who require double lung replacement. Definitive clinical diffusion of the procedure will depend upon intermediate and long-term outcomes for specific recipient pathologies.
