OP11.07: Fetoscopic MMC correction in Chile: Short oral presentation abstracts

Open surgery has been performed locally, with several maternal complications such as uterine ruptures or severe prematurity. Some series may be unreported. Instead, fetoscopic correction has claimed its place because of lower maternal risks. We report our local experience supported by the Brazilian team. Cases are selected with strict MOM-s trial criteria. Surgery was performed with four trocars and biocellulose patch. The first case was operated by the Brazilian team and the second by the local team, with presence of the supporting team. Two cases are operated. The patients: one primigravidae, the second with one previous Caesarean section. Fetuses had L2-5 lesions, with ventriculomegaly (12 and 19mm) and Arnold Chiari II. Both were operated at 27 weeks of GA. The patch could be placed and the skin closed without tension. Both had rupture of the membranes. The first child was born at 33 weeks, with complete skin closure and normal follow-up until 10 months of age. The hindbrain recovered before delivery, no need of valve, and normal development. The second pregnancy is ongoing, without recovery of the hindbrain, and stable ventriculomegaly, at 33 weeks. The surgery has been safe for fetuses and women. Fetoscopic procedure for MMC repair has been feasible with the support of a more experienced team. The procedure is identical in order to lower complications. One case has satisfactory outcome, the second is ongoing. Please note: The publisher is not responsible for the content or functionality of any supporting information supplied by the authors.
