遗传性出血性毛细血管扩张症鼻衄是令耳鼻喉科医生棘手的问题、鼻腔填塞、冷冻、电烙、雌激素、鼻中隔皮瓣成形术、动脉栓塞及动脉结扎等疗法仅在一部分病例有效,且常出现严重副作用。Nd-YAG 激光在光凝及止血方面优予 CO_2激光。作者采用 Nd-YAG 激光治疗该病患者19例,分3组:甲组,既往无需输血;乙组,偶需输血;丙组,需多次输血。使用 Cil-as100W 持续波 Nd-YAG 激光发生器,能量20～30W 照射0.2～0.5秒。手术在显微镜下进行,先将扩张出血的毛细血管其周围照射一周以凝
Hereditary hemorrhagic telangiectasia Epistaxis is a troublesome problem for otolaryngologists. Nasal packing, freezing, electrocautery, estrogen, nasal septoplasty, arterial embolization and arterial ligation are only effective in some cases, And often serious side effects. Nd-YAG laser in the photocoagulation and hemostasis give CO2 laser. The authors used Nd-YAG laser treatment of the disease in 19 patients, divided into three groups: Group A, no blood transfusion in the past; Group B, occasionally transfusion; Group C, need multiple transfusions. Using Cil-as100W continuous wave Nd-YAG laser generator, energy 20 ~ 30W irradiation 0.2 ~ 0.5 seconds. Surgery under a microscope, the first expansion of the blood vessels around the week of exposure to light coagulation
