Endovenous Laser Ablation in the Treatment of Recurrent Varicose Veins

Endovenous laser ablation (EVLA) was evaluated for its effectiveness in treating recurrent varicose veins in patients who had prior surgical interventions. The study found that 15% of patients assessed had previous vein surgery, and the presence of varicose veins was linked to various vein pathologies. EVLA proved to be feasible and effective, with most patients reporting symptomatic improvement post-treatment.

Endovenous laser ablation in the treatment of recurrent varicose veins. Aims: 1. Determine how many patients presented to a single center Vein Specialty Clinic with varicose veins despite prior surgical intervention. 2. Identify the site and cause of varicose veins in patients with prior surgical intervention. 3. Assess the role of endovenous laser ablation in the retreatment of varicose veins in patients with prior intervention. 3

Summary 1. 15% of patients presenting for evaluation of leg vein problems had prior intervention. 9% had prior surgery. 2. Presence of varicose veins associated with segmental or fully intact great saphenous vein, perforator vein pathology, and accessory vein reflux. 3. Short-term, EVLA is feasible and effective in the majority of patients with varicose veins and prior saphenous vein surgery. 4. The majority of EVLA-retreated patients reported symptomatic improvement. 14
