Filter by: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 this research study, the investigators want to learn more about the role of new innovative surgical devices, the Karl Storz Curved and Straight Fetoscopes for in-utero surgery. A fetoscope is like a small telescope that can see inside of the uterus (womb) during minimally invasive surgery. The curved scope is used for patients with an anterior placenta (front of uterus), while the straight scope is used for patients with a posterior placenta (back of uterus). The scopes will be used to assist in procedures involving fetoscopic laser photocoagulation (FLP), which is a minimally invasive surgery that uses a small camera (fetoscope) to locate abnormal blood vessel connections in the placenta and seal them off using laser energy. These fetoscopes will be utilized in the diagnosis and management of various fetal conditions that can arise during pregnancy. Outcome data will be reported in a descriptive statistical analysis. The investigators will assess the surgical outcomes, short and long-term morbidity, complications, and gestational age of participants in order to evaluate the benefit of using these devices.
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.
