[Usefulness of prothrombin fragment 1 + 2 and fibrin dimer in the detection of hypercoagulation in obstetrical patients with thrombosis risk factors].
We measured prothrombin 1 + 2 fragment (f1 + 2p) and dimer D (dD) in plasma from 100 pregnant women at high risk for thromboembolic disease (TED) and in 23 non-pregnant control. Measures of f1 + 2p were made by immunoassay analysis in 75 patients and dD by semiquantitative analysis of plate agglutination in 97 cases. F1 + 2p was significantly elevated in 85% of cases, but its levels was not predictive value for TED. Dimer D was not found in 40 cases, in 33 patients its values were between 500 and 1000 ng/ml. and in the other 24 cases were higher than 2000 ng/ml. Values higher than 1000 ng/ml. were founded in 78% of patients with history of TED, in 60% of cesarean section patients, in 37% of hypertensive patients and in the 23% of diabetic patients. Dimer D, that was higher than 500 ng/ml. in 59% of pregnant and puerperal patients, have predictive value for TED, because 25% of 24 patients that had dD higher than 2000 ng/ml. developed TED and/or coagulation anomalies suggestive of thrombotic activity. These findings were not found in the rest of patients (n 73) which had negative dD or less than 1000 ng/ml.
