BACKGROUND AND OBJECTIVES
Spider leg veins are telangiectasias located intracutaneously. This condition poses a cosmetic problem.
STUDY DESIGN/PATIENTS AND METHODS: The purpose of this study was to determine what influence the KTP (532 nm) laser has on spider leg veins dependent on the vascular diameter and to what extent the skin has been affected. Seventy female patients were treated in three laser sessions. Analysis was done 30 weeks after the last laser treatment session.
RESULTS
Fifty-six patients completed the study. In group 1 (vascular diameter < or = 0.6 mm), spider leg veins were no longer visible in 33%; in 40%, a decrease in vascular diameter could be observed; in 27%, no change in size occurred. In group 2 (vascular diameter 0.7-1.0 mm), laser-treated spider leg veins were visible in all patients. Hyperpigmentation occurred in 13 patients.
CONCLUSIONS
The KTP (532 nm) laser is an effective for treating spider leg veins having a vascular diameter under 0.7 mm.
背景与目的
蜘蛛腿样静脉是位于皮内的毛细血管扩张。这种情况会造成美容问题。
研究设计/患者与方法：本研究的目的是确定KTP（532纳米）激光对取决于血管直径的蜘蛛腿样静脉有何影响，以及皮肤受影响的程度。70名女性患者接受了三次激光治疗。在最后一次激光治疗后30周进行分析。
结果
56名患者完成了研究。在第1组（血管直径≤0.6毫米）中，33%的蜘蛛腿样静脉不再可见；40%的患者可观察到血管直径减小；27%的患者血管大小无变化。在第2组（血管直径0.7 - 1.0毫米）中，所有患者经激光治疗的蜘蛛腿样静脉均可见。13名患者出现色素沉着。
结论
KTP（532纳米）激光对于治疗血管直径小于0.7毫米的蜘蛛腿样静脉有效。
