Imaging findings
Non-contrast CT chest sequence from an acute aortic syndrome protocol demonstrates a crescentic, high-attenuation thickening of the ascending aortic wall. This acute intramural hematoma extends from the aortic root to the proximal descending aorta, following a difficult and prolonged coronary angiogram procedure.
Key takeaways
Acute aortic intramural hematoma can occur as a rare, serious iatrogenic complication of cardiac catheterization, particularly during difficult or prolonged coronary cannulation. Incorporating a non-contrast CT sequence in suspected acute aortic syndromes is vital, as it allows for the clear visualization of hyperdense hematoma within the aortic wall.
