右室异常肌束X线平片诊断的评价

评价Ｘ线平片对右室异常肌束的诊断价值及限度。材料与方法：分析经手术证实的右室异常肌束７３例的Ｘ线平片表现，根据血液动力学改变，将此病分为３型：无分流型；左向右分流型；右向左分流型。结果；在Ｘ线平自上，右室异常肌束可表现下列征象；（１）右室增大与心腰凸出不相称；（２）左室增大与肺血增多不相称；（３）右室流出道入呈局限性缺陷。

The Evaluation of X-ray Plain Film Diagnosis of Anomalous Muscle Bundle of Right Ventricle

Objective: To evaluate the diagnostic value and limit of anomalous muscle bundle of the right ventricle on X ray plain film. Materials and Methods:Analysed 73 cases of anomalous muscle bundle of the right ventricle confirmed by operation. Divided the malformation into three types based on hemodynamics character: (1)No shunt; (2)Left to right shunt; (3)Right to left shunt.Results:On X ray plain film, the signs of the disease may be as follows: (1)The right ventricular enlargement does not suit the dilatation of pulmonary trunk (35/73 cases); (2)The left ventricular enlargment does not match the increased pulmonary flow (15/73 cases); (3)There is a local dent at the right ventricular outflow tract (23/73 cases).Conclusion: The limit of X ray plain film in diagnosis of the malformation is large, but if there are two or three signs above on a chest plain film, and combined with the clinic apperances, the diagnosis of the disease should be pointed out in part obstructive cases. Following ultrasound or angiocardiaography can confirm the existence of anomalous muscle bundle.
