支气管动脉栓塞治疗肺部出血性病变

３５例咯血患者接受选择性支气管动脉和其他供血动脉栓塞治疗４２次。出血的病因包括：支气管扩张１７例，肺癌９例，肺结核４例，特发性肺出血４便，法乐氏四联症１例，栓塞物质为明胶海绵、携药微球及纲丝圈。本组近期疗效９１．４％，２周后复发咯血率２０．２％，但发作次数和出血量明显减少。本研究表明：支气管动脉栓塞是肺部出血性病变有价值的治疗方法，支气管动脉造影是肺部出血性病灶定位诊断的有效方法。

Bronchial Artery Embolization in the Treatment of Hemoptysis

Thirty-five patients with hemoptysis were treated with 42 embolizations of bronchial artery or other feeding arteries.The pulmonary diseases included bronchiectasis(n=17),lung cancer(n =9),tuberculosis(n=4),idiopathic hemorrhage(n=4),and tetralogy of Fallot (n=1).The embolic materials used were gefoam particles; MMC-Dextran microspheres and steel coils.Hemoptysis was immediately controlled in 33 cases(91.4%),The recurrence rate after 2 weeks was 20.O%,the attacks occurred less frequent and less serious.The results of the study indicated that bronchial artery embolization is a valuable method of treating massive hemoptysis and the bronchial arteriography is particularly useful in localizingthe source of bleeding point.
