Abstract

Aim: To compare pathomorphological changes in the venous wall of large diameter great saphenous veins (GSV) after endovenous laser ablation (EVLA) using wavelengths of 1470 nm and 1940 nm. Materials and Methods: We studied 120 specimens of great saphenous veins from 30 patients with chronic venous disease with large-diameter (>1 cm). Patients were randomly divided into two groups. The 1st group received EVLA using wavelengths of 1470 nm, the 2nd group received EVLA using wavelengths of 1940 nm. Four specimens were taken at the level of the lower third of the thigh after laser coagulation in each patient. Vein specimens were processed for histological studies. Both qualitative and quantitative analyses were performed to assess the degree of wall changes. Results: The share of satisfactory results when using 1470 nm laser wavelengths is 83.3%, while when using 1940 nm laser wavelengths this result is 93.3%. When using both wavelengths of laser irradiation with a GSV diameter of more than 1 cm, no unsatisfactory results are observed. Conclusions: Obtained in our study data confirmed efficacy of the 1470 and 1940 nm endovenous laser ablation in the treatment of the large size GSV (more than 10 mm). Histological exams show preferability in the 1940 nm EVLA versa 1470 nm, considering the excellent result in the uniformity of distribution and safety in the deepness of the thermal injury.
1470 nm与1940 nm激光消融大直径大隐静脉的对比分析
目的:比较1470 nm和1940 nm激光消融(EVLA)后大直径大隐静脉(GSV)静脉壁的病理形态学变化。材料与方法:对30例大直径(bbb10 ~ 1cm)慢性静脉疾病患者120例大隐静脉标本进行研究。患者随机分为两组。第一组接受1470 nm波长的EVLA,第二组接受1940 nm波长的EVLA。每个患者在激光凝固后的大腿下三分之一处取4个标本。对静脉标本进行组织学研究。进行定性和定量分析以评估壁的变化程度。结果:激光波长为1470 nm时满意率为83.3%,激光波长为1940 nm时满意率为93.3%。当GSV直径大于1 cm时,使用两种波长的激光照射,没有观察到令人不满意的结果。结论:我们的研究数据证实了1470 nm和1940 nm静脉内激光消融治疗大尺寸GSV(大于10 mm)的疗效。组织学检查显示1940 nm的EVLA优于1470 nm,考虑到热损伤分布均匀性和深度安全性的优异结果。
