Clinical Trial Summary

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.

Intervention

Device:
• Medical Adhesive
Medical Adhesive (produced by Beijing Compont Medical Devices Co., Ltd.) For varicose veins in the main saphenous vein, use 0.1 ml glue for every 3 cm of blood vessels.
• ClosureFast Endovenous Radiofrequency Ablation(RFA) Catheter
ClosureFast Endovenous Radiofrequency Ablation (RFA) Catheter (produced by America Medtronic Inc.) The ClosureFast catheter precisely heats a 7 cm vein segment in one 20-second interval.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Clinical success rate	At 24 weeks after surgery, Doppler ultrasound was used to check the closure of the target blood vessels.	24 weeks after operation.
Secondary	Technical success rate	Immediately after operation, Doppler ultrasound was used to check the closure of the target blood vessels.	Immediately after operation
Secondary	Target vascular closure rate at 12 weeks after operation.	At 12 weeks after surgery, Doppler ultrasound was used to check the closure of the target blood vessels.	12 weeks after operation.
Secondary	Clinical signs	The severity of the patient's clinical presentation was assessed according to the Clinical signs- etiologic classification- anatomic distribution- pathophysiologic dysfunction classification (CEAP classification) criteria.; classification are as follows. C0: Without any visible or palpable signs of disease. C1: Telangiectasia or reticular veins C2: Varicose veins C2r: Recurrent varicose veins C3: Edema is present. C4: Changes in skin and subcutaneous tissue C4a: Pigmentation or eczema C4b: Lipodermatosclerosis or atrophie blanche C4c: Corona phlebectatica C5: Healed ulcers C6: Active ulcers C6r: Recurrent active venous ulcer	Screening period, 12 and 24 weeks after operation.
Secondary	Venous Clinical Severity Score (VCSS)	The VCSS score ranges from 0 to 30, with a larger value indicating approximately severe symptoms.	Screening period, 4 weeks, 12 weeks and 24 weeks after operation.
Secondary	Aberdeen Varicose Vein Questionnaire (AVVQ)	AVVQ scores range between 0 and 33, a higher score indicates a lower quality of life for patients.	Screening period, 4 weeks, 12 weeks and 24 weeks after operation.
Secondary	Operation duration		Immediately after operation
Secondary	Evaluation of product performance	The researchers evaluated the operation performance of the product from the aspects of ease of operation and injection function, and divided the evaluation into three levels: satisfactory, general and unsatisfactory.	within 24 hours after operation
