本文对110例手术证实动脉导管未闭病例作一回顾性复习,并取150名正常人和38例房隔缺损,74例室隔缺损进行对照观察。在动脉导管未闭组交角消失征检出率82％,其中1/3同时兼有漏斗征,而漏斗征检出率为58％,同时兼有消失征达3/4,可见前者比后者检出率高,统计学上差异有非常显著意义(P<0.01),但两者不一定呈平行关系。在正常人,房缺和室缺组中消失征分别为5％、35％、25％。统计学上与动脉导管未闭组对照差异亦有非常显著意义(P<0.01)。结果表明交角消失征对动脉导管未闭诊断敏感性较高和有一定特异性,特别对小的动脉导管未闭病例,结合心脏杂音常可作出较可靠诊断。交角消失征的X线表现为主动脉弓与肺动脉干在正位胸片上投影构成两突出小弧其间交角尖消失或两孤几乎连成一斜行直线影。本文还讨论了消失征形成的病理基础。
This review of 110 cases of patent ductus arteriosus confirmed retrospective review, and take 150 normal subjects and 38 cases of atrial septal defect, 74 cases of ventricular septal defect control. In the patent ductus arteriosus disappeared angle detection rate of 82%, of which 1/3 at the same time both funnel levy, and funnel levy detection rate of 58%, while both disappeared sign 3/4, showing the former than the latter The detection rate is high, the statistical difference is very significant (P <0.01), but the two are not necessarily parallel relationship. In normal subjects, atrial and ventricular remodeling signs were 5%, 35% and 25%, respectively. Statistical differences with the patent ductus arteriosus control group also have very significant (P <0.01). The results show that the disappearance of hips on the diagnosis of patent ductus arteriosus with a higher sensitivity and specificity, especially for small cases of patent ductus arteriosus, combined with cardiac murmur can often make a more reliable diagnosis. X-ray disappeared sign of the performance of the aortic arch and pulmonary trunk projection in the anteroposterior radiographs constitute two prominent arc during the disappearance of the tip of the tip or two solitary almost connected into a straight oblique line of shadow. This article also discusses the pathological basis for the formation of the disappearance sign.
