Abstract

In radiofrequency ablation (RFA), the ions in the tissue surrounding the probe's uninsulated tip are noticeably stirred up by the electrode's high-frequency alternating current. The surrounding tissue experiences thermal coagulation necrosis as a result of the frictional heat.

RFA is used in complicated monochorionic twin pregnancies with selective fetal growth restriction (FGR), TRAP, and TTTS. RFA may also be considered in giant chorioangioma with favorable vascular anatomy and giant sacrococcygeal teratoma with imminent hydrops. It serves as a substitute to laser.

Keywords

monochorionic twin - radiofrequency ablation - selective FGR - twin reversed arterial perfusion sequence - twin twin transfusion syndrome
