A breakthrough medical technique using high-intensity sound waves offers a new way to treat twin-to-twin transfusion syndrome (TTTS), a dangerous condition affecting identical twins who share a placenta. In this rare complication, uneven blood flow results in one fetus becoming undersized while the other grows too large, jeopardizing the survival of both infants. Typically, intervention involves invasive procedures to drain fluid or use lasers to block blood vessels.
Brioney Garrett, whose identical twins Nancy and Margo were at risk during her pregnancy, became one of the first patients to benefit from this new approach at a London hospital. Surgeons utilized a specialized device to direct ultrasound energy toward problematic blood vessels, effectively sealing them without the need for needles or surgical incisions. The 20-minute session successfully restored balance to the twins’ blood flow, and both were born healthy at approximately 34 weeks.
Led by Professor Christoph Lees of Imperial College London, the study demonstrated that the focused ultrasound could accurately target vessels beneath the skin without causing side effects. While the results—published in the American Journal of Obstetrics & Gynecology—are encouraging, researchers emphasize that more extensive trials are necessary to confirm long-term efficacy. For now, the medical community and groups like the Twins Trust view this non-invasive method as a potential turning point for managing high-risk pregnancies.
