Endovenous ablation of the saphenous vein for greater saphenous insufficiency is now widely accepted as a primary treatment. In this study, thirty patients with documented saphenous insufficiency were evaluated using a unique 1319 nm (Sciton Inc. Palo Alto, CA) wavelength. Three different energy levels were used in two or three patients in each group. Follow-up ultrasounds were performed at two days, one month, and three months. Findings by ultrasound reveal all veins were successfully treated with no flow at day two. At one month, two patients showed flow in the previously treated saphenous vein. In each case this was less than 5 cm in length. Results at three months showed no variation. Early studies confirm the 1319 nm is a safe and effective wavelength to use in endovenous ablation.
