The presence of a viable, living fetus is considered a general contraindication to performing a destructive vaginal delivery.

A live fetus is explicitly listed as a contraindication. The lecture gives exceptions to the usual fetal-death prerequisite for a malformation or tumour incompatible with life, but it separately lists a live fetus as contraindicated. A markedly contracted pelvis, obstructing pelvic tumour, imminent uterine rupture, and previous uterine scar are also listed contraindications.\n\n**Key takeaway:** Fetal status and maternal anatomical or uterine risks must be considered before any such procedure.\n\n**Glossary:** **Contraindication**: A condition or circumstance in which a procedure should not be performed; **uterine rupture**: A tear through the uterine wall.
