Objective: The aim was to evaluate the safety and effectiveness of endovenous thermal ablation (EVTA) with or without adding high ligation (HL) for the treatment of incompetent saphenous veins with an aneurysm (>20 mm for the great saphenous vein, >15 mm for the small saphenous vein) close to the junction. Methods: This was a prospective observational cohort study in a single centre. All patients presenting with saphenous aneurysms close to the junction were included. Those with a venous aneurysm more distally, at >2 cm from the junction, or with associated deep venous aneurysms were excluded. Patients were treated with EVTA alone or combined with HL in cases of an aneurysm with a diameter >30 mm. Phlebectomies were performed during the same treatment session. Patients were followed up one and six weeks, and one year after treatment. Duplex ultrasound (DUS) was performed to evaluate occlusion of the vein and aneurysm as well as possible complications such as endovenous heat induced thrombosis (EHIT) or deep vein thrombosis (DVT). Venous clinical severity scores (VCSS) were registered before and one year after treatment. Results: Thirteen patients (15 limbs) were included between February 2012 and January 2015. Eleven limbs were treated with EVTA alone, the remaining four limbs with EVTA and HL. No severe adverse events occurred (no EHIT, no DVT). After one year none of the aneurysms was still visible on DUS and the truncal obliteration rate was 80% (two partial, one segmental recanalisation). Both treatment strategies showed significant improvement of the VCSS at the one year follow up, from a median score of 6 (interquartile range [IQR] 5e 7) to 2 (IQR 1e3) (p ¼ .001). Conclusion: EVTA with or without HL appeared to be a safe and effective treatment for patients presenting with incompetent saphenous veins with an aneurysm close to the junction.
