Clinical Analysis of Endovenous Laser Treatment Combined with High Ligation for Treatment of Varicose Vein

PURPOSE: Endovenous laser treatment (EVLT) for varicose vein has been shown to be an effective method of treatment. But, after EVLT, recurrence due to recanalization of the great saphenous vein has been identified as a complication. This study was performed to evaluate the effectiveness of EVLT combined with high ligation and to assess the recurrence rate. METHODS: Between April 2004 and April 2009, medical records of 163 patients treated with EVLT combined with high ligation and stab phlebectomy were reviewed retrospectively. Duplex ultrasonography was performed before surgery. All patients were followed up with clinical evaluation at 1 week and 1, 3, and 6 months after operation. The mean follow up period was 5.9 months. RESULTS: In total, 178 limbs of 163 patients were reviewed. In our study, almost all (98.8%) patients had symptomatic and cosmetic improvement. We observed complications such as ecchymosis (22.1%), edema (12.9%), pain (5.5%), and in one case, hematoma. Ecchymosis, edema, and pain were controlled by conservative treatment. The patient with hematoma was hospitalized and improved with conservative therapy. There were no cases of recanalization during the follow up period. CONCLUSION: Compared to previous studies, EVLT combined with high ligation showed satisfactory results, with no recurrence. However, the longer operation time and higher cost were issues and further studies are necessary for objective comparison.

Endovenous Laser Treatment (EVLT) Combined with Stab Phlebectomy (SP) for Lower Extremity Varicose Veins

PURPOSE: For the treatment of residual visible tributaries following minimally invasive saphenous vein ablation procedures such as endovenous laser treatment (EVLT) and radiofrequency ablation (RF), a variety of options including observation, sclerotherapy, ultrasonography-guided sclerotherapy, stab phlebectomy (SP) and additional laser therapy have been developed. We performed endovenous laser treatment combined with stab phlebectomy and we evaluated the early results to assess the efficacy and safety of this procedure. METHODS: Between February 2003 and February 2006, one hundred twelve venous insufficiencies of the lower limbs in 106 patients (46 men and 60 women; mean age: 51.7 years) were treated with EVLT combined with SP. According to the CEAP classification, 103 limbs were C2, and nine were C3/C4. 810-nm diode laser energy was delivered percutaneously into the saphenous veins (86 GSVs, 20 SSVs, 6 GSV+SSVs). All patients were followed up on an outpatient basis and duplex ultrasonography (US) was performed 3 months after operation. RESULTS: The mean follow-up period was 2.92 months. All the patients had symptomatic improvement and immediately returned to normal daily activities. The overall complication rate was 36.6% (41 cases), and most of them were minor problems including ecchymosis in 22, paresthesia in 8, induration in 5 and excessive pain in 2. Three cases of cellulitis or thrombophlebitis were present and this resolved with drainage and antibiotics. One case of foot drop developed, but this improved with active physiotherapy within a few months. No postprocedural symptomatic deep vein thrombosis occurred. The recurrence rate of tributaries at 3 months was 13.6%, but these were easily controlled by sclerotherapy if needed. The duplex US-confirmed saphenous vein recanalization rate at 3 months was 5.9%. CONCLUSION: EVLT combined with SP could be a novel minimally invasive modality for treating lower extremity varicose veins with an acceptable complication rate and a low recanalization rate of the saphenous veins. It could lessen the possibility of additional treatments for the residual visible tributaries and so improve the satisfaction index, along with the cosmetic and economic advantages. However, long-term follow up and postoperative duplex US with an additional objective index examination are required to confirm the effectiveness and durability of this operative procedure.
