Perinatal outcome of monochorionic diamniotic twins complicated by selective intrauterine growth restriction according to the umbilical artery Doppler flow pattern: a single-center study using a strict fetal surveillance protocol.

The classification system of MCDA twins complicated by sIUGR according to the UA Doppler flow pattern of the IUGR twin at final examination is correlated with perinatal outcome. Importantly, the UA Doppler flow pattern can change during gestation, which has an impact on the risk of fetal death. Nevertheless, under strict fetal surveillance, the perinatal outcome of these pregnancies is favorable. This article is protected by copyright. All rights reserved.
