小儿双动脉瓣下室间隔缺损46例临床─X线分析

RADIOLOGICAL DIAGNOSIS OF DOUBLY COMMITTED SUB-ARTERIAL VENTRICULAR SEPTAL DEFECT IN CHILDREN

经手术证实的双动脉瓣下室间隔缺损４６例。结合临床、Ｘ线胸片共分为３组：①无并发症的单纯缺损组２８例；②合并肺动脉高压组１２例（其中１例伴动脉导管未闭及主动脉右瓦氏窦瘤）；③合并主动脉右瓣脱垂５例（其中伴主动脉瓣关闭不全４例）及主动脉右瓦氏窦瘤１例。与其它类型的室间隔缺损相比较，讨论了胸部平片诊断的价值、并发症的成因及心血管造影的表现，并强调主动脉根部造影的重要性。

Forty-six surgically proved cases of doubly committed sub-arterial ventricular septal defect were reported. Based on the clinical manifestation and X-ray findings, the cases were divided into three groups : isolated VSD without complication (n=28,61%);complicated by pulmonary hypertension (n=12, 26%;1with PDA and aneurysm of the right sinus of Valsalva); complicated by right aortic valve prolapse (n = 5, 10. 8%, 4 with aortic regurgitation) and aneurysm of the right sinus of Valsava (n=1, 2. 2%).In comparison with other types of VSD, the differences between the diagnostic value of plain chest film, the pathogenesis of complications and the angiocardiographic findings were discussed. The importance of aortic root contrast visualization in assessing lesions complicating aortic valve was stressed.
