CTICasesAortic Rupture and Cardiac Arrest Physiology
Imaging findings
A patient in cardiac arrest/shock showing a compact bolus in the ascending aorta with minimal distal contrast progression, indicating poor cardiac output. Significant extravasation of contrast into the abdominal cavity was observed, along with a narrow IVC and small heart chambers.
Key takeaways
Recognizing the "gradient" effect in the aorta—where contrast fails to diffuse distally—is a critical sign of pulseless electrical activity or poor systemic perfusion, rather than chronic thrombus.
