Cryopreserved Human Umbilical Cord as a Meningeal Patch in Fetoscopic Spina Bifida Repair

Under general anesthesia and tocolysis, in-utero repair begins with a laparotomy that is followed by exteriorization of the uterus. The fetus is then positioned by external cephalic version. Uterine entry will be accessed using 3 cannulas, followed by heated-humidified carbon dioxide insufflation for visualization. Then, fetoscopically the placode will be examined and dissected. The lesion will be repaired using NEOX Cord 1K® (HUC) for closure of the first layer over the neural placode. Primary closure of the skin will then occur, or NEOX Cord 1K® (human umbilical cord) will be used for skin closure at the discretion of the Pediatric Neurosurgeon. Finally, the laparotomy site will be sutured in multiple layers.
