To evaluate the impact of cervical length and cervical pessary application in congenital diaphragmatic hernia (CDH) treated by the fetoscopic endotracheal occlusion (FETO) procedure.
The study group consisted of 80 patients with severe CDH treated by FETO. Cervical length measurement was performed by transvaginal ultrasound in all patients within the 24 h prior to the FETO procedure. The study group (n = 44) had cervical pessaries applied routinely within the 24 h following the FETO procedure, whereas the control group (n = 36) were not offered pessaries and only had cervical length measurement performed.
