Key result
Classic aortic dissection was associated with a significant increase in false lumen area from 5.8 to 9.0 cm2 over 3.3 years (p=0.036), whereas intramural hematoma showed decreased total aorta size.
Why the study?
What are the morphologic changes of the aorta after aortic dissection as evaluated by CT angiography?
Observational (n=43)
What are the morphologic changes of the aorta after aortic dissection as evaluated by CT angiography?
p-value: p=0.036
Long-term CT angiography follow-up reveals distinct morphologic trajectories depending on the type of aortic dissection, with false lumen enlargement in classic dissection and total aorta size reduction in intramural hematoma.
Supports subtype-specific CT surveillance in aortic dissection; leaves open optimal intervals and intervention thresholds.

Choi et al. (2002) conducted an observational in Aortic dissection (n=43). Aortic dissection (classic vs intramural hematoma) vs. Baseline (initial CTA) was evaluated on Morphologic changes in luminal areas (total, true, false, and true/total ratio) (p=0.036). Classic aortic dissection was associated with a significant increase in false lumen area from 5.8 to 9.0 cm2 over 3.3 years (p=0.036), whereas intramural hematoma showed decreased total aorta size.
