Abstract

We report a case of a giant pulmonary artery aneurysm associated with infundibular pulmonary stenosis. Echocardiography disclosed markedly enlarged main pulmonary artery, but no left to right shunt flow at levels of the atrial septum, ventricular septum and the pulmonary artery. Continuous wave Doppler revealed a maximum velocity of 1.5 m/s which corresponded to the pressure gradient between the right ventricle and the pulmonary artery of 9.5 mmHg. Contrast-enhanced multidetector-row computed tomography with a 16-slice scanner revealed pulmonary artery aneurysm with the maximum diameter of 67 mm on axial image.

摘要

我们报告一例与漏斗部肺动脉狭窄相关的巨大肺动脉瘤病例。超声心动图显示主肺动脉明显增宽，但在房间隔、室间隔及肺动脉水平未发现左向右分流。连续波多普勒显示最大流速为1.5m/s，对应右心室与肺动脉之间的压力阶差为9.5mmHg。使用16层螺旋CT扫描仪进行的对比增强多层螺旋CT检查在轴位图像上显示肺动脉瘤，最大直径为67mm。
