Comparative Study
Use of soluble fibrin antigen instead of D-dimer as fibrin-related marker may enhance the prognostic power of the ISTH overt DIC score.
The overt DIC score of the DIC subcommittee of the ISTH includes a fibrin-related marker (FRM) as indicator of intravascular fibrin formation. The type of marker to be used has not been specified, but D-dimer antigen, or fibrin degradation products are used by most investigators. Soluble fibrin complexes have been suggested as more specific indicators of acute intravascular fibrin formation. ⋯ Using MDA D-dimer, and TINAquant D-dimer, 28-day mortality was between 35.5% and 39.3% in patients with overt DIC, and 15.5% to 15.6% in patients without overt DIC. Selection of the FRM as component of the DIC score has a small, but relevant impact on the prognostic performance of the overt DIC score. The present data on the distribution of values may provide a basis for the selection of appropriate cutoff points for assigning 2, and 3 points in the score.

We investigated age- and sex-specific incidence, risk factors, and latency period of a perioperative acute thromboembolism syndrome (PATS) in a large cohort study. We prospectively analyzed data on 21903 consecutive surgery patients to determine the incidence of myocardial infarction, pulmonary embolism, deep venous thrombosis, stroke, and cardiovascular death within 30 postoperative days. Among 255 (1.2 percent) patients with thromboembolism, 105 (0.48 percent) suffered myocardial infarction (mean latency: 5 days), 30 (0.14 percent) suffered pulmonary embolism (6 days), 23 (0.11 percent) suffered deep venous thrombosis (10 days), 97 (0.44 percent) suffered stroke (11 days), and 13 (0.06 percent) died (12 days). ⋯ Risk of thromboembolic event was higher (P<0.0001) in patients with a history of arterial thrombotic events or cancer. Trend analysis indicates that thromboembolic events will increase 3-fold over the next decade. Our findings enable identification of higher risk patients for prophylactic anti-thromboembolic treatment and awareness of the critical postoperative period.
