Breech Fetal Presentation clinical trials

Breech Pelvimetry by EOS® Technique With Change of Maternal Position and Delivery Route

When a patient presents with a fetus in PS after 36+0SA, after acceptance of participation in the study, pelvimetry with evaluation of the height of the fetal presentation by EOS® system in the upright and sitting position will be performed. CT pelvimetry will not be performed. The patient may then be offered an attempt at VME, with clear, fair and appropriate information, after being informed of the data from the right standing EOS® pelvimetry (report and images). VME will be performed according to the recommendations and practice of the department. In the event of failure with a fetus that remains in PS, the choice of delivery route will be decided in consultation with the patient after clear, fair and appropriate information. If the patient wishes to have a vaginal delivery, the pregnancy will be continued without intervention until spontaneous labour or induction in case of indication (premature rupture of membranes (PMR), over term, or intercurrent maternal or fetal pathology). The modalities of the delivery route and/or a possible induction will be discussed between the obstetric team and the patient. If the patient wishes a caesarean delivery in case of persistent PS, the delivery will be scheduled after 39+0SA or earlier if indicated (RPM, intercurrent maternal or fetal pathology). In the case of a successful VME with a fetus that remains in cephalic presentation until labour, management will follow current recommendations. The characteristics of the dimensions and angles of the obstetric pelvis and the height of the fetal presentation in the standing and sitting positions, the performance and success of MEC, the choice of delivery route, and the final delivery route will be recorded.
