Safe, Fast and Effective Solution for Venous Insufficiency Evaluation of a Unique 1319 nm Nd:YAG Laser for the Endovenous Ablation of the Saphenous Vein RON BUSH, MD, FACS Cincinnati, OH Abstract 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. Introduction Endovenous ablation of the saphenous vein for greater saphenous insufficiency is now widely accepted as a primary treatment. Three to five year follow-up continues to support its efficacy. Current wavelengths of laser used include the 810, 940, 980, and 1320 nm. This study evaluated another wavelength, the 1319 nm (Sciton Inc, Palo Alto, CA). Methods Thirty patients were evaluated. Informed consent was obtained. The size of the greater saphenous vein at the sapheno femoral junction ranged from 10-20 mm. All patients had documented saphenous insufficiency. The majority was in CEAP class, 2-4 with one patient in class 5, and one a class 6. 1 | SCITON White Paper

Evaluation of a Unique 1319 nm Nd:YAG Laser for the Endovenous Ablation of the Saphenous Vein Three different energy levels were used and in two or three patients in each group, histological evaluation of a portion of the treated vein was undertaken. Follow-up ultrasounds were performed at two days, one month, and three months. Procedures were carried out as has previously been described.1,2 Access was either percutaneous or by cut down when resecting a small portion of the saphenous vein for histological study. A 600-micron filament was inserted through a 5-Fr. catheter to within 2-3 cm of...

Evaluation of a Unique 1319 nm Nd:YAG Laser for the Endovenous Ablation of the Saphenous Vein Discussion From our early study and preliminary findings, the following observations were made. First, due to the 1319 nm wavelengths greater absorption by water, more transmural damage will occur. There is less absorption by blood as compared to other wavelengths, (i.e., 940, 980, and to a lesser extent the 810 nm). On ultrasound examination during firing there was considerably more steam bubble formation. The sapheno femoral junction must be compressed when using this wavelength during the...

Evaluation of a Unique 1319 nm Nd:YAG Laser for the Endovenous Ablation of the Saphenous Vein Conclusions Early studies confirm the 1319 nm is a safe and effective wavelength to use in endovenous ablation. There appears to be energy damage at the subendothelial level. From initial evaluation, 7.4-8.4 W seems to be the ideal energy level. Long-term follow-up and careful analysis is needed in comparing these higher wavelength lasers to other wavelengths used for the last five years. References 1. Navaro L, Min RJ, Bone.
