Abstract

Two cases are presented in which compression of the right pulmonary artery by thoracic aortic aneurysm was demonstrated using dynamic CT. The patients initially presented with symptoms suggestive of pulmonary embolus and were found to have unilateral absence of perfusion on isotope lung scan. Computed tomography was useful in demonstrating pulmonary artery compression by aortic aneurysm as the cause in both cases, and in demonstrating an aortic dissection in one case.

摘要

本文报告两例通过动态CT显示右肺动脉受胸主动脉瘤压迫的病例。患者最初表现出提示肺栓塞的症状，同位素肺扫描显示单侧灌注缺失。计算机断层扫描在两例病例中均有助于显示主动脉瘤压迫肺动脉是病因，并在一例病例中显示了主动脉夹层。
