简要总结
The purpose of this clinical trial is to evaluate the effectiveness and safety of Medical Adhesive produced by Beijing Compont Medical Devices Co., Ltd. in the treatment of varicose veins in the lower extremities.
The main questions it aims to answer is: What medical problems do participants have when using tissue glue? Researchers will compare Medical Adhesive to ClosureFast Endovenous Radiofrequency Ablation (RFA) Catheter (produced by Medtronic Inc. to see if Medical Adhesive works to treat varicose veins in the lower extremities.
Participants will:
Treated with closed varicose veins of the lower extremity by Medical Adhesive or ClosureFast.
Return to the hospital at 1, 12, and 24 weeks postoperatively for Doppler ultrasound, and at 4, 12, 24 weeks postoperatively for venous scoring.
