Stenotic lesions of the pulmonary arteries can be congenital or acquired. Different etiologies may affect the pulmonary arteries, unilaterally or bilaterally, at different levels. The clinical scenario, age of presentation and the precipitating event may provide clues to the underlying etiology. Diagnosis is important as these lesions may have hemodynamic and clinical consequences. Multidetector computed tomography angiography allows for accurate depiction of these lesions along with a comprehensive assessment of the pulmonary arterial wall, intra- or extraluminal involvement, associated cardiac or extracardiac anomalies, effects secondary to pulmonary stenosis on the cardiac chambers as well as associated causative or resultant lung parenchymal changes.
肺动脉狭窄病变可以是先天性的，也可以是后天获得性的。不同的病因可能会导致单侧或双侧、不同部位的肺动脉受累。临床情况、发病年龄和诱发事件可能为潜在病因提供线索。诊断很重要，因为这些病变可能会对血流动力学和临床产生影响。多排螺旋 CT 血管造影可以准确显示这些病变，并全面评估肺动脉壁、管腔内或腔外受累情况、相关心脏或心脏外畸形、肺动脉瓣狭窄对心腔的继发性影响以及相关的病因或结果性肺实质改变。
