The association between vein-to-vein anastomoses and birth weight discordance in relation to placental sharing in monochorionic twin placentas KU Leuven
INTRODUCTION: This study aims to examine the association between the presence and size of a vein-to-vein (VV) anastomosis and birth weight discordance relative to placental discordance in monochorionic diamniotic twin pregnancies. METHODS: Placentas of two previous prospective studies were included in this retrospective analysis. After injection with color dye, we measured the placental surface of each twin and VV, artery-to-artery (AA), and ...
