目的:探讨经胸彩色多普勒超声心动图(CDFI)在先心病室间隔缺损(VSD)封堵术中的应用。方法:选择膜部室间隔缺损患者10例,使用SSA-270A型彩色多普勒血流显像仪,术前检测VSD部位、大小、缺损上缘与主动脉瓣环的距离,距三尖瓣的距离,选择合适的封堵器。结果:10例患者,8例即刻封堵成功,2例封堵失败。结论:CDFI经胸指导介入治疗在膜周部VSD中起着极其重要的作用。
Objective: To investigate the application of transthoracic color Doppler echocardiography (CDFI) in the occlusion of ventricular septal defect (VSD) in patients with congenital heart disease. Methods: Ten patients with membranous ventricular septal defect were selected. SSA-270A color Doppler flow imaging was used to detect the location of VSD, the size, the distance between the upper edge of the defect and the aortic annulus, the distance from the tricuspid valve Distance, choose the right occluder. Results: In 10 patients, immediate occlusion was achieved in 8 patients and failed in 2 occlusions. Conclusion: The transthoracic interventional treatment of CDFI plays an extremely important role in VSD.
