作者研究了对肺栓塞症患者经导管向肺动脉内注入尿激酶行溶栓疗法的疗效。共3例,均是临床疑为肺栓塞症并经肺核闪烁图确诊,为明确栓塞部位又作了肺动脉造影者。年龄48～67岁,男1例,女2例。行溶栓治疗前作肺动脉造影,选取主要栓塞左右肺动脉的近中央侧,即肺门水平者,在肺核闪烁图上见栓塞几乎使一侧肺缺血。并且主肺动脉 The authors studied the efficacy of transcatheter urokinase-administered thrombolytic therapy in patients with pulmonary embolism. A total of 3 cases were suspected of clinical suspicion of pulmonary embolism and confirmed by pulmonary scintigraphy, for the clear embolization site made pulmonary angiography. Age 48 to 67 years, 1 males and 2 females. Before thrombolysis for pulmonary angiography, the selection of the main embolization of the left and right pulmonary artery near the center of the side of the hilar level in the pulmonary nuclear scintigraphy embolization almost to one side of the lung ischemia. And the main pulmonary artery
