Worth a Double Take? An In-Depth Review of Lung Retransplantation

Abstract

Provided advancements in Lung Transplantation (LT) survival, the efficacy of Lung Retransplantation (LRT) has often been debated. Decades of retrospective analyses on thousands of LRT cases provide insight enabling predictive patient criteria for retransplantation. This review used the Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) guidelines. The PubMed search engine was utilized for articles relating to LRT published through August 2023, and a systematic review was performed using Covidence software version 2.0 (Veritas Health Innovation, Australia). Careful patient selection is vital for successful LRT, and the benefit leans in favor of those in optimal health following their initial transplant. However, the lack of a standardized approach remains apparent. Through an in-depth review, we will address considerations such as chronic lung allograft dysfunction, timing to LRT, surgical and perioperative complexity, and critical ethical concerns that guide the current practice as it relates to this subset of patients for whom LRT is the only therapeutic option available.
