Pulmonary angiography was performed in 125 patients with suspected pulmonary embolism. Standard angiographic techniques were combined with balloon occlusion of pulmonary arterial branches using a double lumen catheter and contrast material injection distal to the occlusion. Vessel opacification was fluoroscopically monitored and images obtained with either a conventional cut-film camera, a spot-film camera, or cineangiography. Balloon-occlusion angiography improved image quality and contributed substantially to the radiographic diagnosis of pulmonary embolism in most patients. The technique is useful in patients too ill to undergo conventional angiography and may be performed at the bedside.
对125例疑似肺栓塞患者进行了肺血管造影。标准血管造影技术与使用双腔导管对肺动脉分支进行球囊闭塞及在闭塞远端注射造影剂相结合。通过荧光透视监测血管显影情况，并使用传统的断层摄影相机、点片相机或血管造影电影摄影术获取图像。球囊闭塞血管造影改善了图像质量，并在大多数患者的肺栓塞影像学诊断中发挥了重要作用。该技术对病情过重无法进行传统血管造影的患者有用，且可在床边进行。
