Hemodynamic consequences, especially in view of a developing pulmonary hypertension are essential factors regarding the course and prognosis of an obstructive airflow disturbance. The characteristic roentgen symptoms of pulmonary vascular changes in a group of patients are collected and statistically evaluated to find those symptoms correlating best with the results of cardiac catheterisation. The importantce of using not a single symptom but characteristic groups of symptoms for the radiological diagnosis of pulmonary hypertension is stressed. Radiological signs of increased pulmonary pressure do not directly correlate to the degree of direct measurements, false positive radiological reports need not be expected. Positive radiological symptoms indicate irreversible anatomical changes in pulmonary circulation. For the individual patient the pulmonary arterial pressure by cardiac catheterisation alone is not sufficient for the diagnosis and prognosis of this case as in obstructive air-way disturbance two definitely different types of diseases, namely type A (emphysema) and type B (bronchitis) with divergent hemodynamic consequences must be distinguished. For this differentiation the radiological evaluation of the anatomical situation is essential.
血流动力学后果，尤其是考虑到正在发展的肺动脉高压，是关于阻塞性气流障碍病程和预后的重要因素。收集一组患者肺部血管变化的典型X线症状并进行统计评估，以找出与心导管检查结果相关性最佳的症状。强调在肺动脉高压的放射学诊断中使用的不是单一症状而是特征性症状群的重要性。肺动脉压力升高的放射学征象与直接测量的程度没有直接相关性，不必预期会出现假阳性放射学报告。阳性放射学症状表明肺循环中存在不可逆的解剖学变化。对于个体患者，仅通过心导管检查获得的肺动脉压不足以用于该病例的诊断和预后评估，因为在阻塞性气道疾病中，必须区分两种截然不同类型的疾病，即A型（肺气肿）和B型（支气管炎），它们具有不同的血流动力学后果。对于这种区分，解剖学情况的放射学评估至关重要。
