Pulmonary artery branch stenosis is a not uncommon congenital lesion, noted in approximately 4% of children at the time of cardiac catheterization. Real-time 2-dimensional echocardiography was used to examine 10 patients with angiographically documented pulmonary branch stenosis. Five cases of pulmonary artery branch narrowing were identified by echocardiography without prior knowledge of angiographic findings. In 5 other patients whose angiographic results were known, the narrowings were identified in 4 of 5 cases. These results demonstrate the feasibility of evaluating pulmonary branch stenosis with the nonionizing, noninvasive method of 2-dimensional echocardiography.
肺动脉分支狭窄是一种并不罕见的先天性病变，在心脏导管检查时约4%的儿童中可见。使用实时二维超声心动图对10例经血管造影证实有肺动脉分支狭窄的患者进行检查。在事先不知道血管造影结果的情况下，超声心动图识别出5例肺动脉分支狭窄。在另外5例已知血管造影结果的患者中，5例中有4例识别出狭窄。这些结果证明了用二维超声心动图这种非电离、非侵入性方法评估肺动脉分支狭窄的可行性。
