Endovenous laser ablation of the small saphenous vein: prospective analysis of 150 patients, a cohort study.

Abstract

To evaluate treatment of the small saphenous vein (SSV) by endovenous laser ablation. A cohort study, occlusion of the vein and safety of the procedure was analysed prospectively. 150 consecutive patients (169 limbs) were treated between August 2006 and January 2008 in an outpatient clinic setting. The average age was 57 years (range 23-87); 82% female; 31% had serious varicose disease (CEAP 3-6). Treated length averaged 23 cm (range 6-53 cm). All patients underwent a standardised assessment comprising digital questionnaire, physical examination and duplex ultrasonography. The SSV was cannulated percutaneously under ultrasound control and perivascular local anaesthesia (tumescent) was injected. An 810 nm diode laser was used, delivering 70 J/cm. Three months post-treatment all patients received a duplex ultrasound of the treated vessel. Complete occlusion of the SSV after 3 months was achieved in 98% of the cases. Two patients (1.3%) had sural nerve paraesthesia. Six patients developed superficial thrombophlebitis. Serious complications did not occur. Endovenous laser ablation for treating the incompetent small saphenous vein is a safe, effective and technically feasible technique.
