Chronic Venous Insufficiency Due to Great Saphenous Vein Incompetence Treated with Radiofrequency Ablation: An Effective and Safe Procedure in the Elderly

Abstract

Chronic venous insufficiency (CVI) with the resultant clinical sequelae significantly reduces quality of life. Most elderly patients with CVI are treated nonoperatively owing to concerns of increased operative risk and therefore suffer more advanced disease. Radiofrequency ablation (RFA) has emerged as a minimally invasive procedure to treat patients with superficial venous insufficiency (SVI) due to great saphenous vein (GSV) incompetence. The purpose of this study was to review our experience using RFA of the GSV to treat CVI due to superficial disease in elderly patients compared to younger patients in terms of procedure-related morbidity and severity of disease at time of treatment. RFA treatment of the GSV was performed in 490 extremities of 421 patients with SVI between March 2001 and December 2002. Indications, medical history, and outcome (operative complications and hospital stay) were compared between 2 groups: Group I: 41 extremities of 35 patients, 70 years if age or older (mean 75 ±4); and Group II: 449 limbs of 386 patients younger than 70 years (mean 47 ±11). The incidence of skin pigmentation and healed/nonhealed ulcers (CEAP 4–6) was significantly higher in the elderly than in the younger group (41% vs 16%, p <0.05). Hypertension, diabetes, and previous myocardial infarction were 2.8, 5.4, and 6.7 times more prevalent in the elderly (p <0.05), respectively. There were no major postoperative complications in either group; 97% of all patients were discharged on the day of operation and there was no difference between the 2 groups in overnight hospital stay. There is a treatment bias against operative management in elderly patients with SVI, as evidenced by their more advanced disease at the time of definitive treatment than their younger cohort. However, operative morbidity is no different compared to the younger subset. RFA is a safe and effective procedure for older patients; therefore, the threshold for operative management of older patients should be lowered.
