“…They emphasized that the higher amount is effective and safe for EVLA treatment. Theivacumar et al (20) reported that the energy amount is the main parameter that affects treatment success, and that 60/cm −1 or greater should be used for successful treatment. In contrast, Kim et al (21) reported 100% technical success using 35.16/ cm −1 in 34 patients.…”

ORIGINAL ARTICLE PURPOSE Endovenous laser ablation has replaced surgical methods in the treatment of saphenous insufficiency. The aims of this study were to compare the effectiveness of 1470-and 980-nm wavelength (WL) laser systems, to compare the postoperative complication rates, and to determine the effect of laser WL on postoperative pain scores. MATERIALS AND METHODSBetween October 2010 and November 2011, 79 consecutive patients with saphenous vein insufficiency were examined. The patients who received the 980-nm treatment were defined as Group 1; 54 extremities of 47 patients were treated in this group. The patients who received the 1470-nm treatment were defined as Group 2; 36 extremities of 32 patients were treated in this group. RESULTSEarly technical success was 100% in both groups. Both major and minor complications were seen in Group 2. The complications in Group 1 were mostly major; however, three minor complications were reported in this group. The complication rates of the two groups were not significantly different. There was no statistically significant difference between the pain scores of the two groups. CONCLUSION Early postoperative pain was the major factor that impaired quality of life. There was no relationship between the postoperative pain scores and laser WL or energy density. The laser WL did not affect technical success or occurrence of complications. Use of a suitable energy density resulted in complete occlusion in all patients with saphenous vein insufficiency. Lower extremity venous insufficiency is a very common medical condition that affects approximately 25% of females and 15% of males (1). Great saphenous vein reflux is the most common underlying cause of symptomatic varicose veins. Other causes are reflux in other truncal veins, such as the small saphenous vein, the anterior or posterior thigh circumflex vein, the Giacomini vein, and perforating veins. Treatment options for varicose veins include conservative management, minimally invasive procedures, and surgery.In 1999, Salat (2) first reported the delivery of endoluminal laser energy with an 810-nm diode laser for the treatment of varicose veins. Early success with this device prompted development of other devices that supplied wavelengths (WLs) more specific to the hemoglobin chromophore (810-, 940-, and 980-nm devices) in an effort to achieve 100% saphenous vein closure (2-7). In contrast to these laser systems, the 1320-and 1470-nm WL laser systems affect interstitial water (8, 9). Goldman (6) introduced the 1320-nm WL, which better exploits water as the energy-absorbing molecule. Two comparative studies indicated that patients treated with water-specific laser WLs reported less postoperative pain, used less painkillers, and were less likely to have ecchymosis (8, 10).There is increasing focus on reducing postoperative pain and bruising, while maintaining high saphenous vein ablation rates. Because the 1470-nm WL is absorbed by water at a level 40-times more than the 980-nm WL, the manufacturer hypothesized that it woul...

“…26 It is possible to provoke adequate closure of the vein using 35, 60 or 80 J/cm; so a safe LEED level was used for treatment with both the bare and the radial fibers. 15,27,28 With relation to the frequency of paresthesia, it was found that tumescence played a protective role with regard to occurrence of paresthesia during the postoperative period, and the comparison with the conventional fiber at 7 days was significant (23.33% vs. 60%). The difference was not statistically significant for the comparison with the double radial fiber group, even though the latter was treated with a greater quantity of energy.…”

Background: Endovenous laser treatment of saphenous veins offers patients a procedure with low rates of complications and an early return to occupational activities. Objective: To compare rates of formation of bruising, of paresthesia along the path of the great saphenous vein (GSV), and of GSV obliteration 30 days after thermal ablation in the thigh, performed with or without tumescence and using two different types of fiber. Methods: This was a prospective study, analyzing three groups of patients who underwent GSV thermal ablation in the thigh, using a wavelength of 1470 nm. Patients in group 1 were treated with a conventional fiber using tumescence; those in group 2 were treated with a conventional fiber without using tumescence; and patients in group 3 were treated with a double radial fiber without tumescence. After 30 days, the rates of obliteration shown by Doppler ultrasonography, of paresthesias, and of bruising were compared. Results: Comparison of the results of thermal ablation of 90 GSVs in the thigh revealed similar rates of obliteration, with no statistical differences. The rate of paresthesia along the path of the GSV in the thigh was higher in the groups without tumescence than in the group with tumescence, but the difference only attained statistical significance for the comparison with the group that was treated with the conventional fiber. There was bruising in all groups, with greater frequency in group 1 (73.33%). Conclusions: Tumescence proved useful for preventing minor neurological injuries, but didn't have any influence on the rates of bruising occurrence or of occlusion of the GSV in the thigh up to 30 days after thermal ablation.
