| Abstract: | Background and Objectives: Current treatment methods of superficial venous insufficiency (SVI) can be painful or result in incomplete occlusion. The objective of this study was to evaluate a technique for laser endovenous ablation with a newly developed diffuser fiber. Study Design/Materials and Methods: Six lateral saphenous veins in three goats were used. A specifically designed diffuser laser fiber tip was employed in all trials to deliver a wavelength of 1,064 nm. Each segment was treated with a different energy fluence by changing the power setting of the laser or the withdrawal rate of the fiber. Energy fluence was calculated by dividing the Joules employed for each segment over the internal surface area of the vessel. Segments were evaluated with ultrasound and histologically. Results: Seventy-five percent of the segments were occluded when an energy fluence of greater than 85 J/cm 2 was employed. No perforations were observed, but perivascular changes were more common at higher energy fluence. Conclusions: Endovenous laser occlusion of veins with minimal perivascular effects can be achieved with laser wave-lengths of 1,064 nm if an energy fluence of 84.9-224 J/cm 2 is employed and circumferential effect is achieved. © 2003 Wiley-Liss, Inc. |
