Q: What level of d-dimer along with clinical signs is predictive of Acute Aortic dissection?


Answer: In acute aortic dissection, usually level more than 500ng/ml is significant. In most cases, in acute aortic dissection this level is reported to be more than 2000ng/ml. D-dimer levels is useful in risk stratifying patients with suspected aortic dissection to rule out aortic dissection if used within the first 24 hours after symptom onset.
