Summary

This study aims to see if a common vein treatment called radiofrequency ablation is safe and helpful for people aged 80 and older with severe chronic venous insufficiency. About 50 participants will receive the procedure and be followed for 6 months. The goal is to measure how well the treated veins close and how much leg symptoms improve.

Inclusion Criteria: 1. Age: Aged 80 years or older. 2. Clinical Diagnosis: Symptomatic chronic venous insufficiency of the lower extremity, with the highest clinical class (CEAP classification) being one of the following: * C3: Venous edema * C4a: Pigmentation or eczema * C4b: Lipodermatosclerosis or atrophie blanche * C5: Healed venous ulcer * C6: Active venous ulcer 3. Confirmed Reflux: Color duplex ultrasound examination confirming reflux (reflux time \> 0.5 seconds) in the great saphenous vein (GSV) and/or small saphenous vein (SSV) of the target limb. 4. Informed Consent: The patient or their legally authorized representative is able to understand and voluntarily provides written informed consent. Exclusion Criteria: * Participants who meet any of the following criteria will be excluded from the study: 1. Mobility: Non-ambulatory or bedridden. 2. Thrombosis: Presence of acute superficial thrombophlebitis of the target vein, or deep vein thrombosis (DVT) in the target limb. 3. Arterial Disease: Significant peripheral arterial disease, defined as an ankle-brachial index (ABI) \< 0.8 in the target limb. 4. Coagulopathy: Uncorrectable coagulation disorder. 5. Allergy: Known severe allergy to local anesthetics (e.g., lidocaine) or relevant device materials. 6. Cognition \& Compliance: Severe cognitive impairment or psychiatric illness that, in the investigator's judgment, precludes adequate understanding and cooperation for the study procedures and follow-up. 7.
