Pregnancy
after the 40th week of gestation is often a great dilemma
for obstetrician in diagnostic, therapeutic and in psychological
terms as well. The aim of this study was to confirm the phenomenon
of placental insufficiency in pregnancy after the 40th
gestation week, the modality of delivery and perinatal outcome. The
study comprised 3405 deliveries in a period of one year, 391 of
which were terminated after the end of the 40th gestation week,
including healthy pregnant women with singleton pregnancies. Control
group included healthy pregnant women delivered between the 37th and
40th gestation week.
The incidence of deliveries after the 40th week of gestation is
11.48%. Non-stress test was reactive in 99.65% of women in the study
group. At the same time, CST (constriction – stress test) was
assessed as negative in 78.67% of cases. The pathological CST was
found in only 1.33% of cases. Doppler ultrasound measurements showed
the increased resistance in umbilical artery flow in 3% of cases.
Vacuum extraction was used for 16.62% of deliveries in the study
group, and 8.73% of deliveries in the control group (c2=23.24;
p<0.001). In the study group, Caesarean section was performed in
14.58% of cases, and in control group in 9.07% (χ2=11.09; p<0.001).
Placental insufficiency induced by duration of pregnancy is a rear
phenomenon in uncompromised pregnancy. There was no significant
difference in the morbidity and mortality rates between the study
and control group. Acta Medica Medianae 2007; 46(4):26-30.
