摘要
目的:本研究的目的是评估两步静脉内激光消融(EVLA)治疗膝下长反流大隐静脉(GSV) (BK)的临床疗效，同时预防隐神经损伤。方法:采用Biolitec 1470 nm激光系统和径向2环细纤维，对370条长时间回流至BK-GSV的腿进行EVLA。膝关节以上GSV以7 W (50-70 J/cm)消融，bk段以5 W (20-25 J/cm)分两步消融。结果:消融长度平均为51 cm，治疗长度超过60 cm者28例。未见隐神经损伤。1个月后，超声检查显示所有治疗的GSV完全闭塞。结论:我们的EVLA方案治疗BK-GSV是一种安全有效的方法。
Prevention of saphenous nerve injury after below-knee laser ablation of incompetent great saphenous veins: A trial of two-step ablation and an early result.
Objectives: The objective of this study was to evaluate the clinical efficacy of a two-step endovenous laser ablation (EVLA) protocol for treating long-reflux great saphenous veins (GSV) below the knee (BK) while preventing saphenous nerve injury.
Methods: A total of 370 legs with long-reflux to BK-GSV underwent EVLA using a Biolitec 1470 nm laser system and a radial 2-ring slim fiber. The above-knee GSV was ablated at 7 W (50-70 J/cm), and the BK-segment was ablated at 5 W (20-25 J/cm) in a two-step.
Results: The average ablation length was 51 cm, including 28 legs treated over 60 cm. Saphenous nerve injury was not observed in any patients. One month later, ultrasonography revealed complete occlusion of all treated GSV.
Conclusions: Our EVLA protocol for treating BK-GSV was found to be a safe and efficient procedure.
