CTICasesAsystole on ECMO Flow Artifact
Imaging findings
Chest and abdomen CT of a patient in asystole on ECMO demonstrates retrograde flow of contrast down the azygos vein, into the hepatic and renal veins, and pooling along the mitral valve and left atrium.
Key takeaways
CT scanning in an asystolic patient on ECMO can produce highly unusual flow dynamics and pooling of contrast in dependent systemic veins and cardiac chambers, mimicking thrombus or vascular anomalies.
