目的　评价经皮穿刺经导管栓塞术治疗肺动静脉畸形 (PAVMs)的安全性和疗效。资料与方法　对 10例PAVMs患者进行了经导管栓塞治疗 ,男 4例 ,女 6例 ,平均年龄 12岁 (6个月～ 2 8岁 ) ,均为先天性。临床表现有紫绀和杵状指 /趾 7例 ,劳力性呼吸困难 6例 ,胸部血管杂音 4例 ,咯血 2例和心功能不全 2例。栓塞时用微型钢丝圈2例 ,普通钢丝圈 8例。结果　PAVMs病灶为多发性 7例 ,单发性 3例。 10例共做栓塞治疗 12次 ,技术成功率为10 0 % ,治疗结束时复查肺动脉造影显示单发病灶完全消失 ,多发病灶者主要异常血管不再显影。术后血氧饱和度从平均 78%增至 96 %。 2例术前存在心功能不全 ,术后症状消失 ;胸部血管杂音消失。术后出现轻微胸痛 5例 ,少量胸腔积液 3例 ;1例术后 2个月死于栓塞肺叶肺梗死继发化脓性感染。 9例随访 18个月～ 9年 ,一般情况良好 ,日常生活正常 ,无神经系统症状和体征 ,除 2例弥漫型动静脉畸形血氧饱和度持续在 85 %～ 90 %外 ,其余缺氧症状未再复发。结论　经导管血管内栓塞术是治疗PAVMs的安全、有效方法 Objective To evaluate the safety and efficacy of percutaneous transcatheter embolization in the treatment of pulmonary arteriovenous malformations (PAVMs). Materials and Methods 10 patients with PAVMs underwent transcatheter embolization. There were 4 males and 6 females with a mean age of 12 years (range, 6 months to 28 years). All were congenital. Clinical manifestations of cyanosis and clubbing / toe in 7 cases, 6 cases of labor-induced dyspnea, chest vascular murmur in 4 cases, 2 cases of hemoptysis and cardiac insufficiency in 2 cases. When embolization with miniature traveler in 2 cases, ordinary travelers in 8 cases. Results PAVMs lesions were multiple in 7 cases, single in 3 cases. A total of 10 cases of embolization were treated 12 times, the technical success rate was 10%. At the end of treatment, pulmonary angiography showed complete disappearance of single lesions, multiple lesions of the main abnormal blood vessels no longer develop. Postoperative oxygen saturation increased from an average of 78% to 96%. Preoperative presence of 2 cases of cardiac insufficiency, postoperative symptoms disappeared; chest vascular murmur disappeared. Postoperative mild chest pain in 5 cases, a small amount of pleural effusion in 3 cases; 1 case 2 months after the death of thromboembolic pulmonary infarction secondary purulent infection. Nine patients were followed up for 18 months to 9 years. They were generally in good condition and had normal daily life without neurological symptoms and signs. Except for 2 cases of diffuse arteriovenous malformation, blood oxygen saturations continued to be between 85% and 90% No recurrence. Conclusion Transcatheter arterial embolization is a safe and effective method for the treatment of PAVMs
