Veno-arterial extracorporeal membrane oxygenation (VA ECMO) causes changes in the filling and blood flow of the cardiac chambers and pulmonary vessels as well as alterations in the path of intravenous contrast injected during CT. We present a patient with a potentially misleading CT pulmonary angiogram while on full VA ECMO. We demonstrate circulatory changes as well as alterations in contrast flow when ECMO flows are reduced.
