The purpose of this study was to evaluate change in the size of the main pulmonary (PA) artery in patients with acute exacerbation of interstitial pneumonia (IP). Twenty-nine patients underwent computed tomography at baseline and at the time of acute IP exacerbation for the measurement of the diameters of the main PA and the ascending aorta. We found that the diameter of the main PA was significantly larger at the time of acute IP exacerbation than at baseline, which might reflect the alterations in pulmonary circulation.
本研究的目的是评估间质性肺炎（IP）急性加重患者主肺动脉（PA）大小的变化。29例患者在基线时和IP急性加重时接受了计算机断层扫描，以测量主PA和升主动脉的直径。我们发现，IP急性加重时主PA的直径显著大于基线时，这可能反映了肺循环的改变。
