作者总结了306例肺出血经导管栓塞治疗的经验,其中225例(73.5％)在出血高峰期进行栓塞。方法包括:①氯氨基甲酸乙脂(Polyurethaue)颗粒栓塞;②用导管或蛋白凝聚微粒临时栓塞;③局部灌注硬化剂。硬化剂用4ml青霉素加入20～40ml 10％氯化钠溶液配成,用以刺激血管内膜,诱发血管痉挛,继发血栓形成。经支气管动脉造影证实并插管成功后进行栓塞治疗。278例(90.8％)止血成功。失败的28例中26例出血来源于肺动脉。止血后24～96小时内复发出血39例(14％),其中只有2例为栓塞血管再通。死亡27例,其中9例死
The authors summarized the experience of 306 patients with pulmonary hemorrhage undergoing catheter embolization, of which 225 (73.5%) embolized at the peak of bleeding. Methods include: ① embolization of urethane (Polyurethaue) particles; ② temporary embolization with catheters or protein aggregates particles; ③ local perfusion hardening agent. Hardener with 4ml penicillin 20 ~ 40ml 10% sodium chloride solution dubbed to stimulate the blood vessel intima, induced vasospasm, secondary thrombosis. Transbronchial arteriography confirmed and successful embolization after intubation. 278 cases (90.8%) had successful hemostasis. Of the 28 failed cases, 26 had hemorrhage originated from the pulmonary artery. In 24 to 96 hours after hemostasis, 39 cases (14%) had recurrent hemorrhage, of which only 2 had recurrent embolism. 27 died, of which 9 died
