为探讨永存动脉干(PTA)的病理分型与临床诊断及其相关性。于1985年1月～1998年10月经超声心动图、心导管和心血管造影检查诊断PTA20例,按照Van Praagh分型法分型。结果:Ⅰ型8例,Ⅱ型5例,Ⅲ型6例,Ⅳ型1例,都伴有室间隔缺损。动脉干均为三瓣,有4例轻度关闭不全。肺动脉压力/主动脉压力为0.85～1.0。结论:明确PTA的病理类型和了解肺血管的阻力对外科手术十分重要。诊断主要依赖超声心动图、心导管和心血管造影检查。临床上心电图电轴不偏,双室肥大;X线胸片肺充血,心影增大合并右位主动脉弓的紫绀型先心病应考虑PTA的诊断。
To investigate the pathological type and clinical diagnosis of perinatal arterial (PTA) and its correlation. In January 1985 ~ October 1998 by echocardiography, cardiac catheterization and cardiovascular imaging diagnosis of PTA in 20 cases, according to Van Praagh classification type. Results: There were 8 cases of type Ⅰ, 5 cases of type Ⅱ, 6 cases of type Ⅲ and 1 case of type Ⅳ, all with ventricular septal defect. Artery stem are three, there are 4 cases of mild incomplete closure. Pulmonary artery pressure / aortic pressure is 0.85 ~ 1.0. Conclusion: A clear pathological type of PTA and understanding of pulmonary vascular resistance is very important for surgery. The diagnosis depends mainly on echocardiography, cardiac catheterization and cardiovascular imaging. Clinical electrocardiogram axis is not partial, double room hypertrophy; X-ray chest pulmonary congestion, increased cardiac arrhythmia with right aortic arch cyanosis should consider the diagnosis of PTA.
