radiofrequency ablation
Also written as: RFA
Minimally invasive technique using thermal energy to ablate abnormal fetal tissues or vascular connections.
Full Definition
Radiofrequency ablation (RFA) in fetal surgery involves the percutaneous insertion of specialized needles that deliver controlled thermal energy to target tissues. This technique is used to treat various fetal conditions including selective reduction in multiple pregnancies, ablation of abnormal vascular connections in twin pregnancies, and treatment of fetal tumors. The procedure is performed under ultrasound guidance with careful monitoring to avoid injury to normal structures.
Usage
Usage note: Often abbreviated as RFA in surgical documentation.
