BACKGROUND
Generalized essential telangiectasia is a rare cutaneous disorder with limited therapeutic options.
OBJECTIVE
To evaluate the treatment with high-energy, high-frequency, long-pulse Nd:YAG laser in a patient with generalized essential telangiectasia.
METHODS
A 62-year-old woman presented with a 20-year history of generalized essential telangiectasia. She had extensive telangiectasias primarily on the forearms and lower legs. The patient was treated with an Nd:YAG laser using a fluence of 20 J/cm2 and a pulse width of 20 msec. A sapphire water-cooled chill tip was used to cool the skin during laser therapy. The treatment was performed every 4 weeks over a period of 6 months.
RESULTS
After six treatment sessions an almost complete clearance of telangiectatic lesions was observed. Side effects such as purpura, scarring, and pain did not occur. After a follow-up of 6 months, small telangiectatic lesions relapsed.
CONCLUSION
Our results suggest that the Nd:YAG laser appears to be an effective and safe treatment option for generalized essential telangiectasia.
背景
泛发性特发性毛细血管扩张症是一种罕见的皮肤疾病，治疗选择有限。
目的
评估高能、高频、长脉冲钕：钇铝石榴石激光治疗泛发性特发性毛细血管扩张症患者的疗效。
方法
一名62岁女性，有20年泛发性特发性毛细血管扩张症病史。她主要在前臂和小腿有广泛的毛细血管扩张。使用能量密度为20 J/cm²、脉冲宽度为20毫秒的钕：钇铝石榴石激光对患者进行治疗。激光治疗期间使用蓝宝石水冷冷却头冷却皮肤。治疗每4周进行一次，持续6个月。
结果
经过6次治疗后，观察到毛细血管扩张性病变几乎完全清除。未出现紫癜、瘢痕形成和疼痛等副作用。随访6个月后，出现了小的毛细血管扩张性病变复发。
结论
我们的结果表明，钕：钇铝石榴石激光似乎是泛发性特发性毛细血管扩张症一种有效且安全的治疗选择。
