Venous radiofrequency ablation is an outpatient procedure that uses radiofrequency energy, delivered through a catheter, to close and eliminate varicose veins. Radiofrequency energy is a form of electrical energy that can penetrate the body and be absorbed without any heat sensation, making it virtually painless. Blood that would normally return toward the heart through the treated vein will travel through other veins instead. Over time the treated vein shrinks and is absorbed by the body. Compared with surgical options like ligation and vein stripping, venous radiofrequency ablation can result in less pain and quicker recovery time
