| Collection Summary: | Amniotic fluid was previously collected and banked from pregnant individuals with monochorionic-diamniotic twins complicated by TTTS undergoing fetoscopic laser ablation of placental anastomoses at the UTHealth Houston Fetal Center at Children’s Memorial Hermann Hospital. Samples were collected from the recipient twin sac immediately upon entry with the operative cannula and prior to placental laser ablation or amnioinfusion for improving the visualization. The amniotic fluid was centrifuged, and the supernatant was stored at -80 C for future use. Frozen genetic amniocentesis samples, discarded from further analyses, served as controls. For TTTS cases, demographics, clinical characteristics, and outcomes were abstracted from the Fetal Center research database which is maintained by trained research staff. For controls, available clinical variables were limited to maternal age, gestational age, indication for amniocentesis, and genetic testing results. |
