Summary

Single-lung transplantation (SLT) effectively treats severe emphysema, improving lung function and patient status. This procedure offers advantages over heart-lung transplantation (HLT), including shorter wait times.

Area of Science:

  • Pulmonology
  • Thoracic Surgery
  • Transplant Medicine

Background:

  • Severe obstructive lung disease, particularly emphysema, significantly impacts patient quality of life and survival.
  • Lung transplantation is a viable therapeutic option for end-stage lung disease.
  • Evaluating single-lung transplantation (SLT) outcomes is crucial for optimizing treatment strategies.

Purpose of the Study:

  • To assess the efficacy and outcomes of single-lung transplantation (SLT) in patients with severe emphysema.
  • To compare SLT outcomes with heart-lung transplantation (HLT) in terms of waiting time, resource utilization, and patient survival.
  • To determine the impact of SLT on pulmonary function and functional status in emphysema patients.

Main Methods:

  • Retrospective review of seven patients with severe emphysema who underwent SLT between August 1989 and September 1990.

  • Pre-transplant cardiac function assessment including right and left ventricular function and pulmonary artery pressure.
  • Post-transplant follow-up to evaluate pulmonary function (FEV1), survival, and hospital resource utilization.

    • Main Results:

    • Pulmonary function, measured by FEV1, significantly improved after SLT (0.76 L pre-op to 1.78 L post-op, p<0.01).
    • Six out of seven SLT recipients survived the follow-up period (17 +/- 5 months), with one death due to pulmonary embolism.
    • SLT recipients experienced shorter waiting times (2.9 months) compared to HLT recipients (9.6 months).

    Conclusions:

    • Single-lung transplantation is an effective treatment for severe emphysema, even in patients with moderate right ventricular dysfunction.
    • SLT offers advantages over HLT, including reduced waiting times, better organ utilization, and less frequent need for cardiopulmonary bypass.
    • SLT leads to marked improvement in pulmonary function and overall functional status for patients with severe emphysema.
