Patients with pulmonary hypertension of unknown cause show a typical radiological pattern with prominence of the pulmonary segment, increase in diameter of the right descending branch of the pulmonary artery and marked tapering of the peripheral vascular bed. The aim of this study was to evaluate if changes in radiological indices correlate with hemodynamic changes during long term follow-up, in 19 patients with pulmonary hypertension followed for a mean of 8.4 years. In 10 patients, an increase in pulmonary arterial pressure (Ppa) was measured, and in all further increase in the diameter of the right descending branch was seen. The prominence of the pulmonary segment increased in only six of the ten patients. In three patients, no change in Ppa and in the radiological signs was noted. But in four of six patients a decrease in Ppa was not followed by changes of the radiological signs. In conclusion, we could show that there is a good correlation between radiological signs of pulmonary hypertension and further increase of pulmonary arterial pressure in patients with pulmonary hypertension, whereas a decrease in pressure is not necessarily reflected by a decrease in the radiological signs.
病因不明的肺动脉高压患者呈现出典型的放射学表现，包括肺段突出、肺动脉右降支直径增加以及外周血管床显著变细。本研究的目的是评估在19例平均随访8.4年的肺动脉高压患者中，放射学指标的变化与长期随访期间血流动力学变化是否相关。10例患者测量到肺动脉压（Ppa）升高，其余所有患者均可见右降支直径进一步增加。仅10例患者中的6例肺段突出增加。3例患者Ppa和放射学征象无变化。但6例患者中有4例Ppa下降后放射学征象未改变。总之，我们可以表明，肺动脉高压患者的肺动脉高压放射学征象与肺动脉压进一步升高之间存在良好相关性，而压力下降不一定表现为放射学征象的下降。
