Endovenous treatment for varicose veins of the lower extremities is an old technique. New technologies such as radiofrequency and laser have revived its indications. Thermal energy which is delivered to the vein wall results in a fibrous retraction and eventually complete obstruction of the vessel.     

静脉腔内激光治疗下肢静脉曲张的疗效观察

目的　评价静脉腔内激光治疗下肢静脉曲张的疗效。方法　 46例患者共 5 4条患肢行单纯激光治疗或大隐静脉高位结扎加激光治疗。结果　所有患者的静脉曲张均闭塞。 19.5 %患者出现肢体淤斑 ,81.5 %患者肢体发生沿大隐静脉行程条索状硬结或硬块 ,11.1%患者皮肤局部麻木 ,1例患者发生皮肤浅表烧伤。所有患者均获随访 ,平均随访 6个月 (3～ 8个月 ) ,均痊愈。无深静脉血栓 ,无局部复发 ,疗效满意。结论　静脉腔内激光治疗是一种安全、有效、微创的治疗方法 ,选择大隐静脉高位结扎加激光治疗则更安全。
