Abstract

Endovenous laser therapy (EVLT) is a recognized option in the treatment of uncomplicated varicose veins. This uncontrolled case series evaluates its effectiveness in the management of chronic venous insufficiency. Patients with a history of active or healed ulcers were selected for EVLT. The procedure was carried out in an outpatient setting over a period of 12 months. Assessment was carried out for evidence of ulcer healing and recurrence, long saphenous vein occlusion, and patient satisfaction at 3, 12, and 22 months. Results are expressed as means with range. EVLT was used to treat 23 limbs in 20 patients with a median age of 59 years (range 32-76) including 12 females and eight males. All patients had evidence of chronic venous insufficiency, graded at C5 or greater on the CEAP classification (C5 16, C6 7). Patients with long saphenous vein insufficiency were included, whereas those with either deep or combined deep and superficial venous incompetence were excluded. The cumulative 3-, 12-, and 22-month healing rates were 87% (20/23), 100% (23/23), and 95% (21/22), respectively. The only patient having a recurrence of ulcers at 22 months' follow-up (CEAP 6) had mid-calf perforator incompetence with recanalized long saphenous vein. Duplex scan demonstrated long saphenous vein occlusion in 100% (23/23), 96% (22/23), and 91% (20/22) at 3, 12, and 22 months, respectively. In all, 84% (16/19) of patients were satisfied with the results of treatment without any major procedure-related complication. These results demonstrate that EVLT, carried out in an outpatient setting, is effective in the treatment and prevention of chronic venous ulcers, with good patient satisfaction and no major complication.
