Abstract:
Objective: To assign tendency to thrombosis in patients with preeclampsia and inherited thrombophilia using thromboelastography (TEG), and therefore to evaluate possible relationship between thrombophilia and preeclampsia. Materials and Methods: Kinetics of clot formation was assessed with TEG analyzer in 49 patients with severe preeclampsia, 54 cases with previous diagnosis of inherited thrombophilia, and 31 controls. Results: 'r', 'k', TMA, coagulation index (CI) parameters were found statistically discrete between patients with inherited thrombophilia and controls. The difference between preeclampsia and control groups was not statistically significant. The difference in a angle was statistically significant between thrombophilics and preeclamptics (p = 0.01), and between thrombophilics and controls (p = 0.004). CI was found statistically lower in thrombophilia group than control group (p = 0.006). Particularly, clot lysis time (CLT) was measured to shorten in preeclampsia when compared with controls and patients with thrombophilia (p = 0.032, p = 0.028, respectively). Conclusions: Not only the inherited thrombophilia group but also preeclampsia group demonstrated elongated clot initiation patterns when compared to the controls. Moreover, apart from the patients with inherited thrombophilia, preeclamptics exposed shorter CLT values indicating a possible increment in clot turn over, which eventually results in increased depletion of coagulation substrates, and thus, increased frequencies of oxidative cycle injury.
