Color flow Doppler: a useful instrument in the diagnosis of funic presentation.

Color Doppler sonography offers the opportunity to evaluate the umbilical cord and to study blood velocity wave forms within the cord. Funic (cord) presentation can be diagnosed unequivocally with color Doppler sonography. Because funic presentation is likely to be the harbinger of cord prolapse, the morbidity and mortality associated with cord prolapse can be prevented if funic presentation is diagnosed before membrane rupture. This article describes the first case in the obstetric literature of funic presentation diagnosed with color Doppler sonography. The potential complications associated with cord prolapse were avoided with a cesarean section.
