boventijds

Boventijds is a Dutch term used primarily in obstetrics to describe a pregnancy that lasts longer than the usual term. It is typically defined as a gestational duration exceeding 42 weeks (294 days) from the first day of the last menstrual period; some guidelines also reference 41 weeks as a threshold for heightened monitoring or induction.

Etymologically, the word combines boven meaning “above” or “beyond” and tijd meaning “time,” denoting a duration that has passed beyond the expected time.

In practice, post-term or boventijds pregnancies are relatively uncommon. The exact share depends on dating methods and definitions but commonly falls in the low single digits when using the >42 weeks criterion.

Management of boventijds pregnancies focuses on careful fetal and maternal monitoring. This may include serial ultrasound assessments of fetal growth and amniotic fluid volume, non-stress tests or fetal heart rate monitoring, and Doppler studies as indicated. Many guidelines recommend considering induction of labor around 41 to 42 weeks to reduce risks associated with prolonged gestation, though decisions are individualized based on maternal health, fetal status, and patient preferences.

Potential risks associated with continuing a pregnancy beyond 42 weeks include placental aging, decreased fetal well-being, meconium-stained amniotic fluid, and a modestly higher risk of stillbirth. With appropriate monitoring and timely intervention when indicated, outcomes for boventijds pregnancies can be favorable.

Outside obstetrics, boventijds is rarely used; in medical contexts it primarily denotes pregnancies extending beyond the established term and the associated clinical management.
