目的探讨腹部三维超声成像技术应用于非胎儿心脏检查的可行性及其应用价值。方法在常规二维超声心动图检查基础上,应用具有腹部三维超声成像功能的彩超仪的腹部三维超声探头对28例二尖瓣狭窄与16例房间隔缺损患者(11例儿童和5例成人)的心脏进行三维超声成像,记录二尖瓣最大开放面积与房间隔缺损最大径,并同手术测值和常规二维超声心动图测值进行对比分析。结果腹部三维超声成像技术可以直观地显示二尖瓣狭窄与房间隔缺损的立体形态特征,所测二尖瓣最大开放面积与房间隔缺损最大径同手术测值(r=0.81和r=0.89)和常规二维超声心动图测值(r=0.79和r=0.85)相关性良好,超声与手术方法测值比较差异无统计学意义(P>0.05)。结论腹部三维超声成像技术可以应用于大多数儿童与部分成人的心脏检查,是对常规二维超声心动图的有益补充。
Objective To investigate the feasibility and application value of abdominal three-dimensional ultrasound imaging in non-fetal cardiac examination. Methods Based on routine two-dimensional echocardiography, 28 cases of mitral stenosis and 16 cases of atrial septal defect (11 children and 5 adults) were retrospectively analyzed by using three-dimensional ultrasound with abdominal ultrasound instrument. Heart of the three-dimensional ultrasound imaging, recording the maximum open area mitral valve and atrial septal defect maximum diameter, and with the surgical measurements and conventional two-dimensional echocardiographic measurements were compared. Results Three-dimensional ultrasound imaging of the abdomen showed the stereoscopic features of mitral stenosis and atrial septal defect. The maximal open area of mitral valve and the maximum diameter of atrial septal defect were the same as those of the atrial septal defect (r = 0.81 and r = 0.89) There was no significant difference between the two methods (P> 0.05). Conclusion Abdominal three-dimensional ultrasound imaging can be applied to cardiac examination in most children and some adults. It is a good complement to conventional two-dimensional echocardiography.
