Vasa Previa Pathway and Alert Card

From the anatomy scan to the planned cesarean. Step 1 shows which ultrasound each pregnancy needs. Step 2 turns a confirmed diagnosis into a dated plan. Step 3 makes an alert card the pregnant woman carries to every visit and to labor and delivery. Every recommendation is taken from the 2024 international expert consensus.

Medical alertKNOWN VASA PREVIA

Unprotected fetal blood vessels run through the membranes over or near the cervix. If the membranes rupture, these vessels can tear and the baby can lose blood quickly.

Do not rupture the membranes. Any vaginal bleeding, leaking fluid or contractions: go to labor and delivery now and show this card.

All recommendations come from: Oyelese Y, Javinani A, Gudanowski B, et al. Vasa previa in singleton pregnancies: diagnosis and clinical management based on an international expert consensus. Am J Obstet Gynecol. 2024;231(6):638.e1-638.e24. PubMed 38494071.

The consensus covers singleton pregnancies only; twin pregnancies were excluded. The panel did not agree on a distance from the internal os that defines vasa previa, and did not reach consensus on routine antenatal corticosteroids or routine admission. This tool supports clinical judgment and does not replace it.
