青少年室间隔缺损合并肺动脉高压胸部平片的诊断价值

The Diagnostic Value of Chest Radiogram for the Ventricular Septal Defects Combined with Pulmonary Artery Hypertension in juvenile

目的 :探讨儿童先心病室间隔缺损合并肺动脉高压的胸片诊断价值。材料与方法 :86例VCD均行心脏B超、心电图 (ECG)、胸部平片以及右心导管检查 ,并经手术证实。胸片测量指标①右下肺动脉直径 (RD) ;②肺动脉段高度(HD) ;③心胸比 (C/T) ;④右心斜径 (RM)。结果 :1、肺动脉压力、缺损大小与肺动脉干内径有密切相关性 ;2、X线胸片测量指标与肺动脉太力有较好的相关性 (P >0 0 5 ) ;3、X线胸片测量指标估评肺动脉压力程度与右心导管检查实测肺动脉压的相关性无显著差异 (P >0 0 5 )。结论

Purpose:To explore the diagnostic value of chest radiogram for the VSD combined with pulmonary artery hypertension in juvenile.Materials and Methods:86 cases of VSD were performed with cardiac B-mode ultrasound,electrodiagram,chest radiogram,right cardiac catheterzation and confirmed by operation.The criterias of measurement of chest radiogram were as follows:①The diameter of right inferior pulmonary artery(RD).②Height diameter of the pulmonary artery(HD).③The cardiothoracic ratio(C/T).④Right cardiac oblique diameter(RM).Results:1.The pulmonary artery pressure and the size of defect was closely correlated with the inner diameter of pulmonary truns.2.Higher correlation was found between the criterial of measurement of chest radiogram and the degree of pulmonary artery pressure.3.There was poorly correlation between the degree of pulmonary pressure (deriving from the criterials of measurement of chest radiogram ) and pulmonary artery pressure (detecting by right cardiac catheterization).Conclusion:RD and RM are helpful in determing the degree of pulmonary artery hypertension.
