摘要目的 观察内窥镜辅助下980 nm波长激光经皮光纤介入治疗静脉畸形的疗效和安全性.方法 167例静脉畸形患者中女102例,男65例,年龄0.5～60岁.皮损见于四肢66例、头面部48例、胸腹部24例、背部13例、颈部10例、阴囊6例.使用980 nm波长激光,固定脉冲0ms ～ 2.5 s,脉宽能量0～20 W,光纤直径400 μm.病灶周围环状浸润麻醉后穿刺,同一穿刺点置入光纤,利用光热效应、热凝固直接或间接破坏血管壁,对于较为深在、重要解剖结构周围的病灶,在内窥镜辅助或者B超引导下行介入治疗.根据瘤体大小及形状,以2～4cm/s的速度往返照射,不同方向扇形插入3～5次直至瘤体缩小甚至消失.再次治疗时间间隔3个月.平均随访4个月.结果 治愈148例(88.6％),显效11例(6.6％),有效4例(2.4％),无效4例(2.4％).有效率为97.6％;159例治疗1次获满意效果,8例需治疗2次,间隔3个月,术后均得到改善;6例(3.6％)术区出现色素沉着,但均较轻微;3例(1.8％)出现皮肤烫伤.3个月后上述症状明显改善.2例(1.2％)有血管再通及病灶残留表现,进行再次手术后得到改善.无出血、瘢痕、肌腱和神经损伤,无功能障碍发生等不良反应.结论 980 nm波长激光经皮光纤介入治疗皮肤静脉畸形,是一种安全、有效的方法.

abstractsObjective To evaluate the efficacy and safety of endoscopy-assisted percutaneous interventional procedure with a 980-nm laser for the treatment of venous malformations.Methods A total of 167 patients with venous malformation were enrolled,including 102 females and 65 males,whose age ranged from 0.5 to 60 years.Skin lesions occurred on the limbs in 66 patients,on the head and face in 48,on the chest and abdomen in 24,on the back in 13,on the neck in 10,as well as on the scrotum in 6.A 980-nm laser operated at pulse width of 0 ms-2.5 s and pulse energy of 0-20 W with a 400 μm-diameter optical fiber.Puncture was performed after circular infiltration anesthesia around skin lesions,and then the optical fiber was inserted at the same puncture point to directly or indirectly destruct the vascular wall by photothermal effects and thermal coagulation.For deep lesions around important anatomical structures,the interventional therapy was performed with the assistance of endoscopy or ultrasound.According to the size and shape of tumors,these tumors were irradiated back and forth with speeds of 2 cm/s-4 cm/s.The optical fiber was also inserted in different directions in a fan-shaped pattern for 3-5 sessions until tumors were shrunken or even disappeared.The time interval between two treatments was 3 months,and all the patients were followed up for 4 months on average.Results Of the 167 patients,148 (88.6％)were cured,11 (6.6％) markedly improved,4(2.4％) improved,and 4(2.4％) unimproved.The response rate was 97.6％.Totally,159 patients were satisfied with the therapeutic effects after 1 session of treatment,and 8 were improved after 2 sessions of treatment with a time interval of 3 months.In addition,mild postoperative pigmentation occurred in 6 (3.6％) cases,and skin burns in 3 (1.8％) cases.After 3 months,the above symptoms were improved significantly.Two (1.2％) patients had vascular recanalization and residual lesions,but they were improved after reoperation.No adverse reactions were observed,such as bleeding,scar,tendon and nerve injuries,and dysfunction.Conclusion A 980-nm laser percutaneously delivered through an optical fiber is safe and effective for the treatment of venous malformation.
