作者对34例咯血患者(男29例、女5例)作支气管动脉造影,分析本法对咯血定位和治疗的价值。平均年龄51(29～78)岁。包括肺结核19例、支气管扩张7例、慢性支气管病4例以及矽肺、肺脓肿后遗症、肺切除后遗症及原因不明各1例。采用局部麻醉,股动脉逆行导管造影,并备有多种类型的导管,以适应显示各动脉分支的选择性插管需要。作造影时不宜同时应用血管收缩剂,以免影响造影的质量。一、支气管动脉造影可发现4类病变:①动脉明显扩张和扭曲;②肺实质内有血管增多区;③造影剂返流至肺循环血管,显示存在分流现象;④造影剂溢入支气管。18例在急诊情况下作造影(大量、反复略
The author of 34 patients with hemoptysis (29 males and 5 females) bronchial artery angiography, analysis of the value of hemoptysis localization and treatment. The average age of 51 (29 ~ 78) years old. Including tuberculosis in 19 cases, bronchiectasis in 7 cases, 4 cases of chronic bronchitis and silicosis, lung abscess sequelae, pneumonectomy sequelae and unexplained in 1 case. Local anesthesia, retrograde catheterization of the femoral artery, and various types of catheters are available to accommodate the need for selective intubation that shows the branching of the arteries. Angiography should not be used at the same time vasoconstrictor, so as not to affect the quality of angiography. First, bronchial artery angiography can be found in four types of lesions: ① arteries significantly dilated and distorted; ② pulmonary parenchyma vessels within the area; ③ contrast agent reflux to pulmonary circulation vessels, showing the existence of shunting; ④ contrast agent overflow into the bronchus. 18 cases in the emergency situation made contrast (a lot, repeated slightly
