Radiofrequency ablation, or RF ablation, is a minimally invasive treatment for certain varicose veins and venous reflux. The procedure uses controlled radiofrequency energy to heat and close the targeted vein.
It is performed through a small catheter rather than through traditional surgical vein removal. Closing the unhealthy vein allows blood to reroute through healthier vessels.
Ultrasound is used to locate the vein and guide the procedure. A catheter is inserted into the affected vein through a small access point. Radiofrequency energy is delivered through the catheter to heat the vein wall.
The treated vein contracts and closes, preventing abnormal blood flow through it. Blood then travels through healthier veins while the body gradually processes the closed vessel.
RF ablation is commonly used to treat certain veins affected by venous reflux. Venous reflux occurs when blood flows backward because vein valves are not functioning properly.
This can contribute to varicose veins, swelling, heaviness, and discomfort. Your provider can determine whether RF ablation is appropriate after an ultrasound evaluation.
Local anesthesia is used around the treatment area to improve comfort. Patients may feel pressure or mild sensations during catheter placement and treatment.
The procedure avoids the large incisions associated with traditional vein surgery. Your provider will discuss what you should expect before the procedure.
Both procedures use thermal energy to close an unhealthy vein. RF ablation uses radiofrequency energy, while laser ablation uses laser energy.
Both are catheter-based minimally invasive treatments. The choice depends on your vein anatomy, medical history, and provider recommendation.
Your provider will give you specific instructions for walking, activity, and wound care. Some patients experience temporary bruising, tenderness, or tightness along the treated vein.
Follow-up may include an ultrasound examination to evaluate the treated area. Always follow your provider’s individualized recovery instructions.
Closing an unhealthy superficial vein generally redirects blood into healthier veins. The body has an extensive network of veins that can carry blood back toward the heart.
The purpose of treatment is to eliminate abnormal blood flow through the targeted vein. Your provider evaluates your circulation before recommending ablation.
