D-dimer Value in Recurrent VTE

Filed under: archives of internal medicine, VTE — medblog @ 8:27 pm

ArchIM 1/23 – This weeks Archives features 3 articles focusing on PE/ VTE.
D-dimer can help us rule out PE due to its high sensitivity, but will the presence of prior VTE result in too many false-positives to make it useful? In Le Gal, et al report that PE was ruled out by negative D-dimer in about 16% of pts with previous VTE, vs about 32% of of those without previous VTE.

Bottom Line: D-dimer can still be useful to rule out PE despite prior VTE, but works only about half as often when compared to patients with no history of VTE.

  1. my 18 yr old daughter has been told that her d-dimer level is 52 and at times has been higher yet no cause can be determined other then sever abdominal pain. we have done MRI and MRV and doplar of legs all negitive however we can’t seem to pin point the cause of the pain..is there any connection to d-dimer and digestive caused ie acid reflux just looking for answers as the doctors that we go to are stumped. Thanks for your assistance.
