Spinal Cord Infarction During Extracorporeal Membrane Oxygenation：A Case Series and Review of the Literature

Background: Little is known about extracorporeal membrane oxygenation (ECMO)-related spinal cord infarction (SCI), and reports regarding this rare and catastrophic complication are rare. Here, we report two cases of ECMO-related SCI that occurred between April and December 2023. Data were collected from patients' medical records, with SCI as the endpoint. We reviewed previously published reports by searching PubMed and summarizing the findings. Case summary: One female patient presenting with multiple traumas required oxygenation support through veno-venous ECMO (VV ECMO) due to pulmonary hemorrhage, while one male patient required circulatory support via veno-arterial ECMO (VA ECMO) concurrently with an intra-aortic balloon pump due to cardiac arrest. Neither patient had preexisting neurological deficits; however, upon weaning from ECMO, they presented with severe neurological deficits of uncertain etiology, subsequently confirmed as SCI using magnetic resonance imaging. Conclusion: ECMO-related SCI remains elusive and intricate, and this is the first report of adult VV ECMO-related SCI.
