Flujo diastólico umbilical intermitente en gestación gemelar monocorial: descripción de un nuevo signo en la exploración Doppler y asociación con mal pronóstico perinatal

The incidence of intermittent diastolic flow is significantly increased in the context of selective intrauterine growth retardation, indicating a poor perinatal outcome in these cases.
