Venography and Selective Ablation for Recurrent Varices after Surgery Using Radiofrequency Ablation Catheter

Figure 1

Schemas of venography and selective ablation technique. Recurrent varicose vein after great saphenous vein surgery is caused by incompetent perforator veins (IPVs) (a). Venography is performed using a 7-French sheath at axial vein around the knee (arrowhead) (b). A 0.025-inch hydrophilic wire is crossed to the femoral vein (FV) (c). A radiofrequency ablation (RFA) catheter is advanced over the 0.025-inch wire to the FV (d). The RFA catheter is pulled back to adjust the border between the FV and branch vein while contrasting from the lumen (e). Endovenous thermal ablation is performed from the IPV to the axial vein (f). GSV: great saphenous vein; AAGSV: anterior accessory great saphenous vein.
