1470nm半导体激光治疗下肢静脉曲张疗效评价

Evaluation of efficacy of endovenous laser treatment with a 1470nm diode laser for lower extremity varicosity

目的比较1470nm(输出功率6W)及810nm(输出功率8W)半导体激光腔内治疗下肢静脉曲张的近期疗效。方法对30例行1470nm激光静脉腔内激光治疗(研究组)和29例行810nm激光静脉腔内激光治疗(对照组)的下肢静脉曲张患者的临床资料进行分析,比较二组的手术成功率、手术时间、术后疼痛、术后住院时间及手术并发症的情况。结果术后3天、3个月,研究组和对照组手术前后静脉临床严重程度评分(VCSS)比较,差异均有统计学意义(P<0.01);二组在手术成功率、手术时间、术后疼痛、术后住院时间及手术并发症方面比较,差异均无统计学意义(P>0.05)。结论采用1470nm波长,输出功率6W的半导体激光腔内治疗下肢静脉曲张是一种安全、有效、节能的微创治疗方法。

Objective To compare the short-term efficacy of endovenous laser treatment(EVLT) between using 1470nm(Output power 6W)and 810nm(Output power 8W)diode laser for lower extremity varicosity.Methods The data of 30 patients with varicose veins treated by EVLT with the 1470 nm diode laser(research group)and 29 patients with varicose veins by EVLT with the 810 nm diode laser(control group)were reviewed and compared in terms of operation success rate,operation time, postoperative pain, postoperative hospitalized duration and operative complications.Results The differences between preoperative and postoperative(3-day and 3-month after operation) venous clinical severity score(VCSS)were statistically significant in both groups(P<0.01). The operation success rate,operation time, postoperative pain, postoperative hospitalized duration, operative complications had no statistical differences between the two groups(P >0.05).Conclusion The 1470 nm wavelength and output power 6W EVLT is a treatment for lower extremity varicosity with advantages of safety,effectiveness, energy saving and minimal invasion.
