Résumé
We aimed to investigate whether transabdominal uterine artery (UtA) pulsatility index (PI) differs between monochorionic (MC) diamniotic and dichorionic (DC) twins and is useful to predict pregnancy complications. A total of 406 uncomplicated twin pregnancies (94 MC, 312 DC) were examined at 22 Median mean UtA PI was 0.68 in DC and 0.75 in MC pregnancies (P = .005). Bilateral notches were observed in one MC pregnancy; unilateral notch was seen in 8 DC (2.6%) and 5 MC diamniotic (5.3%) pregnancies. FGR occurred more frequently in DC twin pregnancies, while intrauterine fetal death in MC. Overall, the sensitivity of the parameters tested was low. Pregnancies with both PI above 95th percentile and presence of notch were all associated with complications, particularly FGR. MC pregnancies have higher mean UtA PI. UtA screening in twins shows lower performances than in singletons for the detection of complications.
