[Comparison between radiograph and hemodynamics in obliterative pulmonary vascular disease].
A radiologic-hemodynamic comparitive study was made in 51 cases of obliterative pulmonary vascular disease. The results showed that the pulmonary arterial pressures were all elevated when their radiologic parameters (RDB, RDB/B, PL/T, C/T, DPA/DHT) had abnormal changes, and they had higher sensitivity (76.5-92.2%), specificity (100%) and accuracy (81.8-93.9%) except for DPA/DHT, and there were certain correlations between radiologic parameters and pulmonary arterial pressures (r = 0.36-0.63, P < 0.05-0.01) except for PL/T. In conclusion the radiologic parameters can be used as qualitative diagnostic parameters for pulmonary hypertension in obliterative pulmonary vascular disease, and some parameters might be helpful for evaluating the level of pulmonary hypertension.
