Key result
MSCTA demonstrated significant differences compared to DSA in displaying the position of entry tears, measuring the distance between the first entry tear and the left subclavian artery as 3.5 mm versus 4.2 mm (p=0.002).
Why the study?
Does MSCTA provide comparable or superior diagnostic value to DSA in patients with aortic dissection?

Absolute Event Rate: 3.5% vs 4.2%
p-value: p=0.002
MSCTA with multiplanar reformation and curved planar reconstruction is an optimal imaging method for diagnosing aortic dissection and evaluating patients preoperatively, performing comparably to DSA in dimensional measurements.
Dong et al. (2016) conducted an observational in Aortic dissection (n=49). Multislice computerized tomography angiography (MSCTA) vs. Digital subtraction angiography (DSA) was evaluated on Distance between first entry tear and left subclavian artery (LSCA) in mm (p=0.002). MSCTA demonstrated significant differences compared to DSA in displaying the position of entry tears, measuring the distance between the first entry tear and the left subclavian artery as 3.5 mm versus 4.2 mm (p=0.002).
