What is RadioFrequency Ablation?

Radiofrequency ablation is a procedure that can be done for a variety of reasons that stops the blood from flowing in a particular area.  Most often in pregnancy, it is utilized as a way to safely selectively reduced a complicated twin pregnancy in which there is concern over a shared placenta. 

How is it done?

RadioFrequency Ablation is done under local anesthesia (lidocaine) in the Maternal Fetal Medicine office.  A small needle is guided to the umbilical cord of the affected twin via ultrasound.  The cord is heated so that the blood vessels in the cord are simultaneously sealed.  This procedure takes approximately 15 minutes.

Who is suitable for RadioFrequency Ablation?

Monochorionic twin pregnancies complicated by:

  • Twin Reversed Arterial Perfusion (TRAP) Sequence
  • Severe discordant lethal anomalies
