Twin-to-Twin Transfusion Sydrome is a disorder that impacts about ten percent of monozygotic (identical) twin pregnancies. Find more answers to Frequently Asked Questions About TTTS.
The only "cure" for TTTS is delivery. Doctors have to weigh the impact of delivering the babies prematurely, and consider the difficult question, "Are they better off in the womb or out?" They may prescribe bedrest and even hospitalization in order to closely monitor the situation and stave off preterm labor until the babies are viable (usually after 28 weeks gestation). Sometimes, an intervention to remove excess amniotic fluid from the recipient baby will be performed to stabilize the situation.
However, within the last ten years, medical technology has made it possible to correct the malformed blood vessels in the placenta by using a laser. Fetoscopic laser coagulation allows a surgeon to see inside the womb through a tiny incision, and seal off the connected blood vessels with a laser.
According to Texas Children's Hospital, one of the leading medical centers in the U.S. for diagnosing and treating TTTS and other fetal abnormalities, "laser ablation has a success rate of up to 80% of one of more of the twins surviving." The technology involves local anesthesia, one small incision and an operating time of 45 minutes to 2 hours.
