Study of the placental characteristics and time of onset of twin-to-twin transfusion syndrome
Copyright © 2020. Published by Elsevier Ltd..
INTRODUCTION: To investigate the correlation between placental superficial anastomoses, placental territory and the umbilical cord attachment site with the time of onset of twin-to-twin transfusion syndrome (TTTS), and to explore the influence of placental characteristics on the time of onset of TTTS.
METHODS: A retrospective analysis was performed on 48 cases of TTTS managed conservatively at the Obstetrics Department of Peking University Third Hospital from April 2014 to April 2019. Placental superficial anastomoses, placental territory, the distance between the insertion points of the umbilical cord were measured after placental dye injection. Correlation analysis was conducted between placental characteristics and the time of onset of TTTS.
RESULTS: (1) The incidence of AA anastomoses was 33.3% (16/48) with a mean total diameter of 2.3 ± 1.4 mm, that of AV anastomoses was 95.8% (46/48) with a mean total diameter of 1.2 ± 0.4 mm, and that of VV anastomoses 22.9% (11/48) with a mean total diameter of 2.3 ± 1.1 mm (2) The time of onset of TTTS was positively correlated with the umbilical insertion ratio (Spearman correlation coefficient = 0.404, P = 0.004), but not correlated with the total diameter of anastomoses in the three different types, or with placental territory discordance.
DISCUSSION: The time of onset of TTTS was positively correlated with the umbilical insertion ratio, which suggest that the distance between umbilical cord insertion sites may affect the time of onset of TTTS. The smaller the distance between the umbilical cord insertion sites, the earlier the time of onset of TTTS is likely to be.
