心导管术是诊断心脏大血管病的一种重要方法。准确的心导管检查对先天性心血管病的诊断具有重要价值。层流现象是影响心导管术准确性的重要因素之一。我们仅就层流的误诊问题分析如下,以期对心导管术诊断的准确性提供帮助。临床材料本组取完整心导管术材料46例,男20,女26,年龄5～43岁,平均年龄13.5岁。46例中,室间隔缺损(VSD)25例,房间隔缺损(ASD)18例,动脉导管未闭(RDA)2例,右室双出口(DORV)1例(经右心室造影协助诊断)。与手术结果相符41例,符合率占89.1%;部分符合2例,占4.4%;完全不符合3例,占6.5%46例中16例有层流现象,其中 ASD 7例,VSD8
Cardiac catheterization is an important method of diagnosing cardiovascular macrovascular disease. Accurate cardiac catheterization is of great value in the diagnosis of congenital cardiovascular disease. Laminar flow is one of the important factors affecting the accuracy of cardiac catheterization. We only misdiagnosis of laminar flow as follows, in order to provide the diagnosis of cardiac catheterization accuracy. Clinical material This group of complete cardiac catheterization material 46 cases, 20 males and 26 females, aged 5 to 43 years old, with an average age of 13.5 years. Of the 46 patients, 25 had ventricular septal defect (VSD), 18 with atrial septal defect (ASD), 2 with patent ductus arteriosus (RDA), and 1 with double outlet right ventricle (DORV). In line with the surgical results in 41 cases, the coincidence rate accounted for 89.1%; partly meet the 2 cases, accounting for 4.4%; completely does not meet the 3 cases, accounting for 6.5% 46 cases of 16 cases of laminar flow phenomenon, including ASD 7 cases, VSD8
