OBJECTIVE To evaluate the incidence, type and severity of cerebral injury in the surviving monochorionic (MC) cotwin after single fetal demise in twin pregnancies. METHODS All MC pregnancies with single fetal demise that were evaluated at the Leiden University Medical Center between 2002 and 2013 were included. Perinatal characteristics, neonatal outcome(More)
OBJECTIVE To assess for lenticulostriate vasculopathy (LSV) on cranial ultrasound (cUS) scans of very preterm infants: incidence and aetiology, evolution during neonatal period, association with clinical parameters, and MRI equivalent. DESIGN Prospective study. SETTING Tertiary neonatal referral centre. PATIENTS Very preterm infants (<32 weeks)(More)
Single intrauterine fetal demise in monochorionic (MC) twins may result in acute exsanguination from the surviving twin into the low-pressure circulation of the demised co-twin through the vascular anastomoses. This may lead to severe hypoxic-ischemic injury in the surviving twin due to hypovolemia, hypotension and anemia, resulting in multiorgan damage.(More)
Vasa previa is a condition in which one or more fetal blood vessels run through the amniotic membranes and cross or run near the external orifice of the uterus. Rupture of membranes can lead to tearing of these vessels and cause acute fetal exsanguination. In monochorionic twin (MC) pregnancies, acute exsanguination in one twin can lead to severe(More)
OBJECTIVE To estimate the incidence, risk factors, severity and outcome after perinatal asphyxia in monochorionic (MC) versus dichorionic (DC) twins. METHODS We included all consecutive near-term MC and DC twins with perinatal asphyxia admitted to our neonatal ward between 2004 and 2013 and compared the perinatal characteristics and neonatal outcome(More)
To investigate in preterm infants associations between Diffusion Tensor Imaging (DTI) parameters of the posterior limb of the internal capsule (PLIC) and corpus callosum (CC) and age, white matter (WM) injury and clinical factors. In 84 preterm infants DTI was performed between 40–62 weeks postmenstrual age on 3 T MR. Fractional anisotropy (FA), apparent(More)
