Ultrasound has revolutionised the management of multiple pregnancies and their complications. Increasing frequency of twin pregnancies mandates familiarity of all clinicians with the relevant pathologies and evidence-based surveillance and management protocols for their care. In this review, we summarise the latest evidence relating to ultrasound surveillance of twin pregnancies including first trimester assessment and screening, growth surveillance and the detection and management of the complications of monochorionic pregnancies including twin-to-twin-transfusion syndrome, selective fetal growth restriction, twin reversed arterial perfusion sequence and conjoined twinning.
Since the introduction of ultrasound into routine obstetric practice, the advantages for the mothers carrying twins have moved beyond the simple ability to identify multiple pregnancies antenatally to the possibility of screening these pregnancies both for the same pathologies as those screened for in singleton pregnancies, as well as the identification and management of those complications specific to twin pregnancies.
As twins continue to increase in frequency, 4 routine ultrasound surveillance for the complications of twin pregnancies is becoming a common task and, therefore, familiarity with the clinical problems specific to twin pregnancies is important for all team members. National guidelines recommend that women with twin pregnancies are looked after by a core multidisciplinary team, which includes obstetricians, midwives and sonographers, who are familiar with the management of complicated and uncomplicated twin pregnancies, in order to optimise their outcomes.
