Purpose
To investigate and compare the efficacy and safety of endovenous treatment using 980-nm, 1,470-nm endovenous laser ablation (EVLA), and radiofrequency ablation (RFA) in recurrent great saphenous vein (GSV) insufficiency.
Materials & Methods
From August 2005 to July 2014, a total of 37 limbs in 29 patients (8 men and 21 women; mean age, 53.2 years) those were treated endovenously for recurrent varicose vein of GSV after previous ligation ± stripping for incompetent GSV were evaluated retrospectively. Clinical/Etiology/Anatomy/Pathophysiology (CEAP) classes were C2 in 33 limbs and C3 in 4 limbs. Seventeen limbs among 13 patients, 11 limbs among 9 patients, and 9 limbs among 7 patients were treated by EVLA with a bare-tipped 980-nm laser, a bare-tipped 1,470-nm laser, and by RFA, respectively. Pre-and post-procedural Duplex ultrasonography (DUS) study, Venous Clinical Severity Score (VCSS) and adverse events such as ecchymosis, pain, paresthesia, deep vein thrombosis, or skin burns were examined at 1 week, 1, 3, 6, and 12 months after endovenous treatment.
Results
Endovenous thermal ablation of recurrent GSV insufficiency was technically successful in 37 of 37 limbs (100%). Complete closure was achieved in 35 limbs (94.6%, 35/37) at 12-month follow-up. Two limbs those were treated with 980 nm EVLA were recurred at 1-month and 6-month follow-up, and complete closure was achieved after the second EVLA. Ecchymosis grade was significantly low in RFA and 1470 nm EVLA groups compared with 980 nm EVLA group (p < 0.05), respectively. There was significant decrease of VCSS in RFA group compared with 980 nm and 1470 nm EVLA groups (p < 0.05).
Conclusions
Endovenous thermal ablation using either EVLA or RFA is a safe and effective treatment for closure of the recurrent GSV insufficiency. RFA and 1470 nm EVLA caused less ecchymosis than 980 nm EVLA. Furthermore, significant decrease of VCSS was noted in RFA compared with EVLA (980 nm and 1470 nm).
