Short-term outcomes after third-time lung transplantation: A single institution experience.

BACKGROUND: Reoperative lung transplantation (LTx) survival has improved over time such that a growing number of patients may present for third-time LTx (L3Tx). To understand the safety of L3Tx, we evaluated perioperative outcomes and 3-year survival after L3Tx at a high-volume US LTx center. METHODS: This retrospective study included all patients who underwent bilateral L3Tx at our institution. Using an optimal matching technique, a primary LTx (L1Tx) cohort was matched 1:2 and a second-time LTx (L2Tx) cohort 1:1. Recipient, operative, and donor characteristics, perioperative outcomes, and 3-year survival were compared among L1Tx, L2Tx, and L3Tx groups. RESULTS: Eleven L3Tx, 11 L2Tx, and 22 L1Tx recipients were included. Among L3Tx recipients, median age at transplant was 37 years and most (73%) had cystic fibrosis. L3Tx was performed median 6.0 and 10.6 years after L2Tx and L1Tx, respectively. Compared to L1Tx and L2Tx recipients, L3Tx recipients had greater intraoperative transfusion requirements, a higher incidence of postoperative complications, and a higher rate of unplanned reoperation. Rates of grade 3 primary graft dysfunction at 72 hours, extracorporeal membrane oxygenation at 72 hours, reintubation, and in-hospital mortality were similar among groups. There were no differences in 3-year patient (log-rank p = 0.61) or rejection-free survival (log-rank p = 0.34) after L1Tx, L2Tx, and L3Tx. CONCLUSIONS: At our institution, L3Tx was associated with similar perioperative outcomes and 3-year patient survival compared to L1Tx and L2Tx. L3Tx represents the only safe treatment option for patients with allograft failure after L2Tx; however, further investigation is needed to understand the long-term survival and durability of L3Tx.
