Abstract
<p>Purpose of this study is to determine the effect of laser energy of endovenous laser treatment (EVLT) on venous occlusion and minor complications such as bruising and delayed tightness. Thirty six great saphenous veins were included in this study. Laser fiber was inserted in the vein under ultrasound guidance, and EVLT was performed by using 810-nm diode laser with energy at 14W (nロ27) or 10W (nロ9) in continuous mode. With 14W, complete occlusion was observed in all veins except I case of no-occlusion and I case of partial re-canalization (92.6%). With 10W, complete occlusion was observed in all veins except I case of partial re-canalization (88.9%, P>0.05). Bruising/delayed tightness were noticed in 33.3% and 74.1% with 14W, respectively, while 11.1% (P<0.05) and 77.81% with 10W, respectively. To reduce the laser energy from 14W to 10W may decrease a rate of bruising after maneuver and may not decrease a rate of venous occlusion.</p>
