Background/Objectives: The use of intraoperative venoarterial extracorporeal life support (VA ECLS) has traditionally been used to support unstable patients undergoing complex lung transplantation. More evidence is emerging that the use of intraoperative VA ECLS may be beneficial for all patients undergoing lung transplantation. The aim of this study was to report the safety and feasibility of lung transplantation with the routine use of central VA ECLS. Methods: In this single-center retrospective observational study, all consecutive patients undergoing lung transplantation from April 2021 until September 2025 were included. Early outcomes and the incidence of primary graft dysfunction were evaluated with the International Society for Heart and Lung Transplantation criteria at 72 h after transplantation. Survival and chronic lung allograft dysfunction (CLAD)-free survival were reported with Kaplan–Meier estimates and 95% confidence intervals (CIs). Results: During the study period, 35 patients were successfully transplanted with the aid of central VA ECLS. There were no complications associated with intraoperative ECLS. One revision surgery was performed for immediate postoperative bleeding, and one for bronchial anastomosis air leak. Operative mortality occurred in three patients (8.6%). The median in-hospital stay was 30 (25–43) days. Severe primary graft dysfunction at 72 h was observed in four (11.4%) patients. Survival and CLAD-free survival at 1-, 3-, and 5-years following surgery were 85% (95% CI [74–98]), 74% (95% CI [59–92]), 67% (95% CI [28–82]), and 82% (95% CI [70–96]), 52% (95% CI [37–74]), 36% (95% CI [11–59]), respectively. Conclusions: Lung transplantation can safely be performed with the aid of central VA ECLS, with a low rate of primary graft dysfunction and favorable long-term outcomes. Further follow-up studies and greater experience are needed to make inferences on the long-term outcomes. This technique is relatively recent and evolving, representing an innovative intersection of advanced supportive technology with transplant surgery, potentially broadening indications and improving success rates.
