Maternal outcomes
4/70 women (6%) with known outcomes were admitted to intensive care [ITU] (critical care level 3). Of these women, 3 women were admitted with sepsis (with a background of chorioamnionitis). Two of these had previously undergone invasive, prenatal intervention for MC twin complications earlier in pregnancy. There was more than 6 weeks between the procedure and ITU admission. One woman was admitted for suspected “mirror syndrome” (severe pre-eclampsia in association with a hydropic fetus). The maximum length of stay in ITU was 2 days (range 1-2 days). No maternal deaths or other major maternal morbidities were reported.
