OC22.04: The importance of gestational age at laser surgery in TTTS

Abstract

0.67 *chi-square testIf deliveries by planned Cesarean section and deliveries following induced labor are excluded, 872 twin pairs remain, where 28.6% were MMP, 44.6% were MFP and 26.8% were FFP. Mean GA at delivery was 246.8 days (SD 20.4) for MMP, 245.5 days (SD 21.8) for MFP and 246.2 days (SD 21.2) for FFP (p>0.05). The distribution of preterm and very preterm births was similar in the three groups. Conclusions: Mean GA at birth does not seem to be correlated to fetal gender in twin pregnancies.

Chorioamniotic membrane separation after fetoscopy in monochorionic twin pregnancy: incidence and impact on perinatal outcome

“…In our dataset, gestational age at surgery was the main factor influencing the occurrence of CMS. Our findings are in agreement with those of previous studies suggesting a poorer outcome when fetoscopy was performed at an early gestational age, particularly before 18 weeks' gestation. Thus, a higher prevalence of CMS could partially contribute to the poorer outcome of early fetoscopy.…”

Preoperative prediction of the individualized risk of early fetal death after laser therapy in twin‐to‐twin transfusion syndrome

“…10 The relation of Quintero stages with the risk of early IUFD after laser has been evaluated in various studies with inconsistent results. [11][12][13][14] It has been suggested that earlier gestational age (GA), 15 Doppler parameters such as absent or reversed umbilical artery (UA) end-diastolic flow (EDF) in the donor, 9,16,17 and elevated middle cerebral artery peak systolic velocity (MCAPSV) in the recipient 18 are associated with the increased risk of early IUFD.…”
