[Critical evaluation of fibronectin in pregnancy-induced hypertension/pre-eclampsia and placental insufficiency].

1. Fibronectin does not correlate with the grade of proteinuria. 2. Fibronectin does not correlate with birth weight. 3. Fibronectin level is not elevated in pregnancy-induced hypertension and preeclampsia. 4. Fibronectin level is elevated in cases of preeclampsia, combined with chronic placental insufficiency respectively intrauterine growth retardation. 5. There is a statistic significant difference between pregnancy-induced hypertension/preeclampsia with or with out placental insufficiency. 6. Extremely problematic pregnancies ended in all pregnancies with values of fibronectin above 0.4 g/l in caesarean section without knowledge of the elevated fibronectin level at the time of operation. 7. In the group of pregnancy-induced hypertension the fibronectin level is elevated in relation to control group. This increase is particularly evident, if a placental insufficiency is concontinant with preeclampsia.
