Comparison of Radiofrequency Ablation With Concomitant or Staged Treatment for Tributary Varicose Veins

Condition(s) studied

Investigational drug(s) / intervention(s)

Staged surgery group: The patient is placed in the supine position, and then a DUS examination of the GSV in the affected limbs will be performed. At the appropriate site, local anesthesia will be performed, and the ultrasound-guided Seldinger technique will be used to puncture the main trunk of the GSV 10cm above and below the knee joint. When the needle puncture is successful, we will insert the guidewire, and a 7F vascular sheath (Terumo) will be inserted along the guidewire. Then, we will insert the radiofrequency catheter and advanced the tip to approximately 2 cm at the junction of the saphenofemoral vein, where it will be left in place. Under ultrasound guidance, the needle will be tightly attached to the GSV sheath, and an anesthetic solution will be injected to treat the swelling until the junction of the saphenofemoral vein will be reached. Then, we will secure the tip of the radiofrequency catheter and switch on the radiofrequency generator and ablated the primary trunk of the GSV in segments.

Concomitant surgery group: While the experimental group receives ablation alone, the control group received 1% polidocanol foam sclerosant injection and/or point excision treatment for the pre-marked calf segment branches of the GSV after ablation treatment. Both groups will wear elastic bandages for 24 hours postoperatively, followed by thigh-length class II compression stockings for 1 week after bandage removal.

Study summary

The purpose of this clinical trial is to know which is better to treat the branch vein at the same time or in stages during radiofrequency ablation. The main questions it aims to answer are:

Does the patient who did not treat the branch vein in the first stage of operation need to intervene again? Are there any differences in patients' indexes between the two surgical strategies?

Participants will:

Radiofrequency ablation with or without foam sclerosing agent therapy One week, three months and six months after operation, go to the clinic for a reexamination.

Record their symptoms
