The inferior vena cava (IVC) contrast level sign refers to a contrast-fluid level seen in the IVC on an arterial phase contrast-enhanced computed tomography (CT) scan. This sign has been documented in conditions including cardiac tamponade, myocardial infarction, and cardiac arrest. When this sign is detected, the patient requires immediate attention, with resuscitation initiated as needed, and the referring clinician alerted as soon as possible.
