The aim of this study was to determine the feasibility of identifying velamentous insertion of the umbilical cord during routine obstetric ultrasound.<\/jats:p><\/jats:sec><jats:sec><jats:title>Design<\/jats:title><jats:p>This was a prospective, cross\u2010sectional ultrasound study in 832 unselected second\u2010 and third\u2010trimester singleton pregnancies. Color Doppler ultrasound was routinely performed to identify the placental cord insertion site. The role of three\u2010dimensional (3D) ultrasound in evaluating the placental cord insertion site was also studied in a subset of 50 pregnancies from this population.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The placental cord insertion site was identified in 825\/832 (99%) cases. Visualization was not achieved in seven third\u2010trimester pregnancies with a posterior placenta. A velamentous insertion was suspected prenatally in eight cases, seven of which were confirmed after delivery as velamentous and one as markedly eccentric (battledore placenta). 3D ultrasound performed poorly at evaluating placental cord insertion site, being less efficient due to poor\u2010quality resolution and far more time\u2010consuming than the combined use of gray\u2010scale and color Doppler ultrasound.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Velamentous insertion of the umbilical cord can reliably be detected prenatally by gray\u2010scale and color Doppler ultrasound. 3D imaging had limited value in the evaluation of the placental cord insertion site in our subset of patients. Systematic assessment of the placental cord insertion site at routine obstetric ultrasound has the potential of identifying pregnancies with velamentous insertion and, therefore, those at risk for obstetric complications including vasa previa.
