CTICasesAortic Arch Dissection with Arch Calcification Displacement
[...]. Aortic Arch Dissection with Arch Calcification Displacement. CTICases. Published December 7, 2019. https://str-case-explorer.pages.dev/c/yg4cu
Imaging findings
Chest radiographs and CT show acute widening of the aortic arch and displacement of intimal calcification from the outer wall. CT chest confirms a Type A aortic dissection with stagnant flow (contrast level) in the false lumen and hemopericardium.
Key takeaways
Widening of the aortic contour and displacement of intimal calcification by more than 1 cm on chest radiographs are classic signs of aortic dissection. Hemopericardium from retrograde extension into the aortic root is a surgical emergency.
