Objective: To present the feasibility of fetal myelomeningocele (MMC) repair through a mini-hysterotomy and to describe the perinatal results from our initial experience. Methods: A descriptive study of cases of fetal MMC correction via mini-hysterotomy performed between 2014 and 2016. Results: Forty-five women underwent fetal surgery and 87% (39/45) delivered. A complete multilayer correction of the MMC was possible in all cases. There were no maternal, fetal or neonatal deaths. No maternal or fetal complications occurred from fetal MMC correction until maternal hospital discharge. The average gestational age (GA) at surgery was 24.5 weeks (standard deviation, SD: 1.7; range: 20.7-26.9). The median hysterotomy length was 3.05 cm (SD: 0.39; range: 2.50-3.50). One patient (1/39; 2.6%) experienced chorioamniotic separation. Nine patients (9/39; 23.1%) had premature preterm rupture of membranes at a median GA of 34.1 weeks (range: 31.1-36.0). The average GA at delivery was 35.3 weeks (SD: 2.2; range: 27.9-39.1). Ninety-five percent (37/39) of our patients had an intact hysterotomy site at delivery. Ventriculoperitoneal shunt placement was necessary for 7.7% (3/39) of the neonates. Conclusion: Fetal MMC repair is feasible through a mini-hysterotomy. This approach appears to be associated with reduced risks of very preterm delivery and maternal, fetal and neonatal complications.

Objective: To analyze the impact of gestational age (GA) at the time of fetal open spinal dysraphism (OSD) repair through a mini-hysterotomy on the perinatal outcomes and the infants' ventriculoperitoneal shunt rates.Methods: Retrospective study of cases of fetal OSD correction performed from 2014 and 2019.Results: One hundred and ninety women underwent fetal surgery for OSD through a mini-hysterotomy, and 176 (176/190:92.6%) have since delivered. Fetal OSD correction performed earlier in the gestational period, ranging from 19.7 to 26.9 weeks, was associated with lower rates of postnatal ventriculoperitoneal shunting (P: .049).Earlier fetal surgeries were associated with shorter surgical times (P: .01), smaller hysterotomy lengths (P < .001), higher frequencies of hindbrain herniation reversal (P: .003), and longer latencies from surgery to delivery (P < .001). Median GA at delivery was 35.3 weeks. Multivariate binary logistic regression showed that both fetal lateral ventricle-to-hemisphere ratio (%; P < .001; OR: 1.14 [95% CI: 1.09-1.21]) and GA at the time of fetal surgery (P: .016; OR: 1.37 [95% CI: 1.07-1.77]) were independent predictors of postnatal ventriculoperitoneal shunting.Conclusion: Fetuses with OSD who were operated on earlier in the gestational interval, which ranged from 19.7 to 26.9 weeks, were less prone to receiving postnatal ventriculoperitoneal shunts.

PRISM II is a reliable and easy performing tool for assessing the prognosis of non-accidental cranial traumatism in young children. GCS and PTS, scores even simpler than PRISM II, showed good accuracy regarding survival prediction.

Objective:To analyze the impact of gestational age (GA) at the time of fetal open spinal dysraphism (OSD) repair through a mini-hysterotomy on the ability of children to walk. Methods:Children who underwent in utero repair of OSD and had formal neurological assessment after 2.5 years of age were compared regarding their ability to walk in relation to pre-surgical predictors.Results: Sixty-nine children fulfilled the inclusion criteria. Among them, 63.7% (44/ 69) were able to walk with or without orthesis. Fetal OSD correction performed earlier in gestation (from 19.7 to 26.9 weeks) was associated with a higher probability of walking with or without orthesis (p = 0.033). The median GA at delivery was 35.3 weeks. Multivariate binary logistic regression showed that the upper anatomical level of the OSD ( L5) (p < 0.004; OR: 10.31 [95% CI: 2.07-51.28]) and GA at the time of fetal surgery (p = 0.026; OR = 0.68 [95% CI: 0.48-0.95]) were independent predictors of the postnatal ability to walk with or without orthesis. Conclusion:Fetuses with OSD who were operated on earlier in pregnancy (range: 19.7-26.9 weeks), were more likely to walk with or without orthesis. Key pointsWhat is known about this topic?Children who undergo an in utero correction of an open spinal dysraphism have better neurological outcomes than those who are treated after birth � Children who undergo an in utero correction of an open spinal dysraphism at an earlier gestational age are less prone to needing postnatal ventriculoperitoneal shunts What this article adds? � Children who undergo an in utero correction of an open spinal dysraphism at an earlier gestational age have increased probability of walking with or without orthesis 1634 -Prenatal Diagnosis.
