Endovenous laser ablation has replaced surgical methods in the treatment of saphenous insufficiency. The aims of this study were to compare the effectiveness of 1470- and 980-nm wavelength (WL) laser systems, to compare the postoperative complication rates, and to determine the effect of laser WL on postoperative pain scores.
Between October 2010 and November 2011, 79 consecutive patients with saphenous vein insufficiency were examined. The patients who received the 980-nm treatment were defined as Group 1; 54 extremities of 47 patients were treated in this group. The patients who received the 1470-nm treatment were defined as Group 2; 36 extremities of 32 patients were treated in this group.
Early technical success was 100% in both groups. Both major and minor complications were seen in Group 2. The complications in Group 1 were mostly major; however, three minor complications were reported in this group. The complication rates of the two groups were not significantly different. There was no statistically significant difference between the pain scores of the two groups.
Early postoperative pain was the major factor that impaired quality of life. There was no relationship between the postoperative pain scores and laser WL or energy density. The laser WL did not affect technical success or occurrence of complications. Use of a suitable energy density resulted in complete occlusion in all patients with saphenous vein insufficiency.
静脉内激光消融术已取代手术方法，用于治疗大隐静脉功能不全。本研究旨在比较 1470nm 和 980nm 波长（WL）激光系统的有效性，比较术后并发症发生率，并确定激光 WL 对术后疼痛评分的影响。
2010 年 10 月至 2011 年 11 月，检查了 79 例大隐静脉功能不全患者。接受 980nm 治疗的患者定义为第 1 组；该组 47 名患者的 54 条肢体接受了治疗。接受 1470nm 治疗的患者定义为第 2 组；该组 32 名患者的 36 条肢体接受了治疗。
两组的早期技术成功率均为 100%。两组均出现主要和次要并发症。第 2 组的并发症主要为主要并发症；然而，该组报告了 3 例轻微并发症。两组的并发症发生率无显著差异。两组的疼痛评分无统计学差异。
术后早期疼痛是影响生活质量的主要因素。术后疼痛评分与激光 WL 或能量密度之间没有关系。激光 WL 不影响技术成功率或并发症的发生。使用合适的能量密度可使所有大隐静脉功能不全患者的静脉完全闭塞。
