Key facts
- A new study highlights a pioneering procedure using high-powered sound waves to treat twin-to-twin transfusion syndrome (TTTS).
- The non-invasive treatment seals blood vessels causing uneven blood flow between identical twins.
- Identical twins Nancy and Margo were born healthy after undergoing the procedure.
- The treatment involves firing focused ultrasound waves at tiny blood vessels in the placenta.
- The procedure blocked blood flow in 90% of treated vessels without adverse side-effects.
A groundbreaking procedure utilizing high-powered ultrasound waves has demonstrated the potential to treat twin-to-twin transfusion syndrome (TTTS), a serious and rare condition affecting identical twins during early pregnancy. This non-invasive method seals problematic blood vessels without the need for surgery, offering new hope to affected families.
Twin-to-twin transfusion syndrome occurs when blood flow between identical twins sharing a placenta is uneven. This imbalance results in one twin receiving too much blood and fluid, while the other receives too little, placing both at significant risk. The condition affects approximately 10-15% of identical twin pregnancies sharing a placenta, equating to 300-400 pregnancies annually in the UK.
In a study conducted at Queen Charlotte's and Chelsea Hospital, Brioney Garrett's identical twins, Nancy and Margo, were successfully treated using this novel technique. The procedure, which took about 20 minutes, involved firing focused ultrasound waves at tiny blood vessels in the placenta. Unlike traditional treatments that often require inserting needles or telescopes into the womb, this method was described as quick and painless.
Following the treatment, Nancy and Margo were born healthy at nearly 34 weeks gestation, weighing over 3 lbs each. Now four years old, they are thriving and preparing to start school. Researchers involved in the study expressed excitement about the non-invasive approach but emphasized the need for larger trials to confirm its effectiveness for wider clinical use.
The study reported that the procedure successfully blocked blood flow in 90% of the targeted blood vessels, with no reported unwanted side-effects. Experts believe that if further studies confirm its efficacy, this technique could significantly improve outcomes for many pregnant women facing TTTS, offering a less invasive and potentially safer alternative to existing treatments.
