title: [Vasa praevia diagnosis during transvaginal measurement of cervical length as preventing preterm delivery in the second quarter].
abstract: BACKGROUND
  Vasa praevia is a rare pregnancy complication with a high fetal mortality when not diagnosed in the prenatal period.
  
  
  METHODS
  two cases of vasa praevia diagnosed during the second trimester ultrasound cervical measurement.
  
  
  CONCLUSIONS
  We propose carry out further investigation about cost effectiveness of double vaginal screening (cervical length measurement and vasa praevia) during the second trimester morphology ultrasound. This implementation could allow to reduce the high mortality associated to this obstetric complication.
