M. Hofmann et al., EVALUATION OF HEMOSTASIS PARAMETERS BEFOR E AND AFTER DELIVERY IN PREGNANCIES WITH SIH AND PREECLAMPSIA COMPARED WITH NORMAL PREGNANCIES, Zeitschrift fur Geburtshilfe und Perinatologie, 200(3), 1996, pp. 104-108
Pregnancy is accompanished by a physiological activation of intravascu
lar coagulation: however without disorder. Normal markers of coagulati
on are unchanged despit activation. Special coagulation parameter - su
ch as Thrombin-Antithrombin-III-complex (TAT) or D-Dimer are increased
also in normal pregnant women. Pregnancy induced hypertension (SIH) a
nd preeklampsia may be associated with a disorder of coagulation that
preceedes the well known clinical manifestation of hypertension. There
fore it was the aim of the study to distinguish both the pregnancy ind
uced hypertension (15 patients) and preeklampsia (10 patients) as far
as it is possible by coagulation parameters such as thrombin generatio
n (by TAT), fibrinolysis (by D-Dimer), AT-III. platelets and others co
mparing them with 25 normotensive pregnancies. In preeklampsia, the re
sults showed that clinical signs were associated with simultaneous coa
gulation abnormalities. TAT and D-Dimere are significant increased whe
reas a decrease of AT-III and platelets was observed. There are no sig
nificant differences between SIH and normal pregnancies. Three days al
ter delivery there was an increase of D-Dimer, AT-III and platelets an
d a decrease of TAT-complex in all groups. For risk pregnancy, the par
ameters TAT and D-Dimer may be useful as screeningtest. They although
may support confirming the diagnosis of preeklampsia.
