This study compares the effectiveness of veno-arterial (V-A) and veno-venous (V-V) extracorporeal membrane oxygenation (ECMO) in lung transplantation. Analyzing 62 patients over eight years, results show that V-A ECMO provides superior pulmonary circulatory unloading and improved survival outcomes. Patients on V-A ECMO had lower pulmonary artery pressure, better oxygenation, and reduced pulmonary edema compared to V-V ECMO. Findings suggest V-A ECMO should be the preferred choice when clinically appropriate.
