Gámez-Varela A, Martínez-Rodríguez M, López-Briones H, et al. - Researchers herein examined the predictive performance of preoperative cervical length (CL) for delivery within 1 week after pleuroamniotic shunting (PAS) in fetuses with severe hydrothorax. An accumulation of fluid within the fetal pleural space accompanied with severe bilateral lung compression, mediastinal shift, polyhydramnios, and/or hydrop defined severe fetal hydrothorax. They assessed a total of 35 pregnancies with severe fetal hydrothorax treated with PAS. PAS was performed at median gestational age of (weeks + days) 31 ⁺² (range, 26+0–36+1). Delivery within the first 24 h and 1 week after PAS were recorded in two (5.7%) and 7 (20.0%) cases, respectively. Per outcomes, identification of a short cervix before fetal intervention is predictive of delivery within 1 week after PAS in pregnancies with severe fetal hydrothorax candidates.
