There are several ways to treat varicose veins of the lower limbs, among which use of 1470nm diode lasers stands out. This technique can be used to treat patients in outpatient settings, with early return to work, good esthetic results, and low rates of complications. However, variables such as the laser wavelength, the power administered in each area, the type of fiber, and the linear intravenous energy density (LEED) are still extensively discussed.
To analyze the results of superficial venous insufficiency treatment with a 1470nm diode laser.
Retrospective study conducted at a private clinic in a private hospital in Florianopolis, based on a database collected prospectively. The sample comprised 287 patients who underwent surgery to treat superficial venous insufficiency with 1470nm diode laser, from January 2016 to December 2018, totaling 358 great saphenous veins (GSVs) and 84 small saphenous veins (SSVs) treated.
The total occlusion rates after 12 months of surgery were 94.4% in the GSVs, with an average LEED of 45.90 J/cm, and 96.4% in the SSVs, with an average LEED of 44.07 J/cm.
During the follow-up period, the 1470nm diode laser proved to be a safe treatment, with great efficacy and low rates of complications (pain, edema, bruising, deep vein thrombosis, and endothermal heat-induced thrombosis - EHIT).
下肢静脉曲张有多种治疗方法，其中1470nm二极管激光的应用较为突出。该技术可用于门诊治疗患者，患者能早日恢复工作，美观效果良好，并发症发生率低。然而，诸如激光波长、每个区域施加的功率、光纤类型以及线性静脉能量密度（LEED）等变量仍在广泛讨论中。
分析1470nm二极管激光治疗浅静脉功能不全的效果。
在弗洛里亚诺波利斯一家私立医院的私人诊所进行回顾性研究，基于前瞻性收集的数据库。样本包括2016年1月至2018年12月期间接受1470nm二极管激光手术治疗浅静脉功能不全的287例患者，共治疗358条大隐静脉（GSV）和84条小隐静脉（SSV）。
术后12个月，GSV的总闭塞率为94.4%，平均LEED为45.90 J/cm；SSV的总闭塞率为96.4%，平均LEED为44.07 J/cm。
在随访期间，1470nm二极管激光被证明是一种安全的治疗方法，疗效显著，并发症发生率低（疼痛、水肿、瘀伤、深静脉血栓形成和内热诱导血栓形成 - EHIT）。
