Summary

In this research study, the investigators want to learn more about the safety and effectiveness of a fetal surgery, known as fetoscopic laser photocoagulation (FLP), for the treatment of a pregnancy condition called vasa previa (VP). Vasa previa is a pregnancy complication that happens when blood vessels from the fetus grow over the entrance to the womb. In a VP pregnancy, natural vaginal birth is deadly for the baby in more than half of cases due to the bursting of VP vessels and severe blood loss. Currently, VP patients are recommended to be closely monitored and often hospitalized once they reach the third trimester of pregnancy. An early delivery by C-section would typically be performed in order to avoid breaking the exposed fetal vessels.

Fetoscopic laser photocoagulation is a minimally invasive surgery in the womb to remove or correct abnormal blood vessels and tissues. In the FLP procedure, the surgeon uses a fetoscope (a tiny telescope) and a laser device to seal off unprotected vessels. While this surgery has been used to treat other pregnancy conditions, it has not yet been proven to be safe and/or effective for the treatment of vasa previa. This treatment aims to eliminate the VP, and, if successful, may have the potential to minimize the risk of bleeding, thereby enabling patients to avoid long hospitalization before delivery. This procedure may enable VP patients to have a vaginal delivery instead of C-section.

  • In Utero Procedure Affecting Fetus or Newborn

Interventions

DEVICE

Fetoscopic Laser Photocoagulation

Pregnant patients diagnosed with type II vasa previa will undergo fetoscopic laser photocoagulation of the involved fetal vessels. FLP will be performed laparoscopically using a fetoscope (tiny telescope) and a laser device inside of the womb. This procedure will be completed at 30w0d to 32w6d gestational age.
