The use of a diagnostic algorithm that includes the Wells' criteria and a D-dimer
concentration can exclude PE without CTPA in 20% to 30% of patients.
That patient with the DVT diagnosis met none of the three YEARS criteria and had a D-dimer
level of 480 ng/mL, and so did not undergo CT pulmonary angiography, investigators said.
To evaluate the relationship of D-dimer
, CD147 and miR-203
Group 1 (control group): Blood was obtained from the ear of the rabbits to determine the IL-2, IL-6, PCT, and D-dimer
levels without surgery.
Effectiveness of managing suspected pulmonary embolism using an algorithm combining clinical probability, D-dimer
testing, and computed tomography.
The association between plasma D-dimer
levels and community-acquired pneumonia.
The researchers found that PE was diagnosed in 28 women (7.1 percent; proximal deep venous thrombosis found on ultrasound, positive CTPA, and high probability ventilation/perfusion [V/Q] scan) and was excluded in 367 women (clinical probability and negative D-dimer
result, negative CTPA result, normal or low-probability V/Q scan, and other reasons).
Conclusion: This study demonstrated that systemic sclerosis (SSc) patients with diffuse subset are characterized by increased plasma D-dimer
values, reflecting a potential activation of both the hemostatic and fibrinolytic cascades, which might finally predispose these patients to thrombotic complications.
Mouabbi presented a single-center retrospective study of 102 matched patients who presented with lower extremity swelling and had a CBC drawn, as well as a D-dimer
test, on the same day they underwent a lower extremity Doppler ultrasound evaluation.
Recent studies revealed that high D-Dimer
levels may predict the existence of a pseudoaneurysm.
A positive result was determined for 21 (84%) of the 25 patients for which D-Dimer
was examined (Table 2).
