About this study

Official title: Optimal Management of Vasa Previa: Screening, Diagnosis and Management - A Retrospective Study.

This is a multicenter retrospective observational study of women diagnosed with a vasa previa during pregnancy or at delivery who delivered between 2000 and 2012. The study hopes to be able to describe techniques utilized to screen for and diagnose vasa previa as well as to describe the maternal characteristics and identify potential underlying risk factors that may provide a basis for future screening recommendations for vasa previa and treatment protocols.

Read the detailed description

This is a multicenter retrospective study of women identified as having a vasa previa during pregnancy or at the time of delivery who delivered between January 1, 2000 and December 31, 2012 at participating centers. The primary objective of the study is to describe techniques utilized to screen for and diagnose vasa previa.

  • In those cases that were diagnosed antenatally, to describe the different management protocols utilized, correlate these management protocols with neonatal outcomes and support the management protocol that offers optimal outcomes for both mother and neonate.
  • In those cases that were not diagnosed antenatally, to describe the clinical scenario surrounding delivery and the neonatal outcomes. Review the ultrasound reports and maternal characteristics to identify any potential risk factors for vasa previa that could have been identified antenatally in attempt to improve neonatal outcomes in the future.
  • In all cases of diagnosed vasa previa (those diagnosed antepartum, intrapartum, and postpartum), to describe the maternal characteristics and identify potential underlying risk factors that may provide a basis for future screening recommendations and protocols. Due to the rarity of this diagnosis, the study hopes to include 100-250 participants.

Vasa PreviaWomen with the diagnosis of Vasa Previa made during the pregnancy or at time of delivery who delivered between January 1, 2000 and December 31, 2012.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Diagnostic Profile of Techniques Utilized to Screen for and Diagnose Vasa Previa During Pregnancy.

    The primary outcome of the study it to describe antenatal techniques utilized to screen for and diagnose vasa previa. Vasa previa is when unprotected blood vessels implanted in the membranes or sac run from the placenta across the inside of the woman's cervix. Antepartum ultrasounds were conducted according to standard of care. Here we report the count of participants who were diagnosed during routine ultrasound exam. After initial diagnosis by ultrasound, Vasa Previa's were followed up by routine ultrasounds for confirmation prior to delivery.

    Measured: Participants will be followed from time of diagnosis of vasa previa until the baby is born, an expected time frame of 9 months

  2. Gestational Age at Time of Diagnosis Stratified by Diagnostic Profile.

    Measured: Participants will be followed from time of diagnosis of vasa previa during the second trimester up until delivery.

  3. Mode of Delivery Stratified by Diagnostic Profile.

    Mode of delivery (C/S - emergent, non-emergent, vaginal) stratified by diagnostic profile

    Measured: At birth.

  4. Gestational Age of Infant at Birth

    Gestational age of the infant noted in weeks at the time of birth

    Measured: At birth.
