Rezumat: In Romania, postterm pregnancies are defined as
pregnancies which last beyond 41 weeks and 0 days
of gestation. The determination of the “true” postterm
pregnancies remains challenging, due to incorrect
gestational dating. Therefore, it is widely accepted that
the ultrasonographic measurement of crown-rump length
(CRL) (having an error of 4.7 days) is the most accurate
method of dating gestational age, being superior to
exclusively second-trimester fetal biometry. The maternal
complications rise exponentially through the five weeks
of “term” pregnancies. The pathophysiological basis for
the increased fetal risk in postterm pregnancies is unclear,
although it has been long suggested the role played by
the placental senescence; the most frequently associated
fetal risk of the postterm pregnancy is the meconial
aspiration syndrome. Thus, the question remains: when
should the intervention for delivery outrun the expectative
management? The delivery becomes necessary when the
fetal and/or maternal risks associated with the continuation
of pregnancy are greater than those faced after delivery. Cuvinte cheie: prolonged pregnancy, induction of labor,
conservative management, accurate dating.
