目的：观察65例继发孔性筛孔型房间隔缺损（ASD）患者的超声心动图表现，总结筛孔型ASD的超声特征，为临床进一步处理提供影像学依据。方法：应用iE33、iU22型彩色多普勒超声诊断仪，多切面多角度观察房间隔，综合判断筛孔型ASD的大小、形态、缺损孔的数目，根据超声检查结果对不同类型的筛孔型ASD给予不同的临床干预处理意见。结果：65例筛孔型ASD病例中双孔型缺损33例，多孔型缺损32例，常伴有房间隔瘤形成，超声的特征性表现为房间隔中部成筛孔样回声中断，彩色血流显像为宽窄不一的左向右分流束。结论：多切面多角度观察房间隔对于筛孔型ASD极为重要，超声心动图对于筛孔型ASD病例的观察及处置对策有重要的临床指导意义。

Objective: To summarize the echocardiographic features of multiple foramen atrial septal defect(ASD) by observing 65 cases of multiple foramen atrial septal defect. Methods: We observed the ASDson multiple sections and angles by iE33 or iU22 diasonograph and analyzed the number, shape and size of ASD. According to the ultrasonic inspection results, different clinical intervention opinions were given according to different types of multiple foramen ASD. Results: There were 33 double foramen and 32 multiple foramen which were often associated with atrial septal aneurysm. The characteristic echocardiographic appearance included mesh-like echo interruption and different shunts from left to right in color modes. Conclusion: It is important to observe multiple foramen ASD on multiple sections and angles. Echocardiography has important clinical significance for multiple foramen ASD.
