However, different treatment methods have different results.1 In 1997, Bergan first applied endovenous laser treatment (EVLT) for varicose veins, which has been applied in China since 2003.
The data of the patients who received EVLT from Jan.
The most common indication for EVLT was large bulging varicosities and accompanying symptoms such as lower extremity swelling, eczema, pigmentation, stasis dermatitis, and ulceration.
We used an 810 nm semiconductor laser (Dornier MedTech, Italy) with 600 um-diameter optical fibre6 (however, other authors think that EVLT using a 1,320 nm-laser achieves better clinical outcomes, as well as lower recurrence and recanalisation rates than EVLT using an 810 nm laser.).7 An 18 gauge needle, 0.035 in ultrasmooth guide wire, 4/5 F catheter was used.
The mean energy was 6515 J (ranging from 1000 J to 11330 J), and increasing energy delivery had no significant effect on EVLT morbidity and complications for superficial venous insufficiency.2
This includes cutting and ligating the GSV and its tributaries, stripping the trunk of the GSV, and removing other local varicose veins.5 The main purpose of a variety of surgical methods for treating varicose veins is to eliminate varicose veins, with endovenous ablation effectively reducing symptoms of superficial venous insufficiency.11 Incomplete removal of the great saphenous vein is the most common cause recurrent varicose veins, hence, there is a need to relieve venous hypertension and prevent recurrence.12 EVLT combined with high ligation is based on the principles of the operation.13,14
Recanalisation has been reported after simple EVLT,13 although recanalisation has not been found by B-ultrasound in our centre.
The rate of varicose vein recurrence in the EVLT without SFL group is similar to that in the EVLT with SFL group.
In a large single centre experience Ravi et al (2006) found no differences between EVLT and RFA in terms of their efficacy or complications (Ravi et al 2006).
Common complications with both EVLT and RFA include thrombophlebitis, haematoma formation, extension of thrombus into deep veins, paresthesia and inadvertent burns.
