摘　　要：对30倒房间隔缺损（ASD），12例室间隔缺损（VSD）患者进行多平面经食管体元模型动态三维重建超声显像研究。结果表明：超声动态三维重建可从多个角度和方向，甚至模拟手术路径立体显示ASD和VSD的形态、部位和相对大小，及它们和邻近解剖结构间的关系。25例经手术证实的患者中，三维重建纠正了1例ASD和1例VSD患者的多平面经食管二维超声诊断，2例ASD患者三维重建补充了原来的诊断。Thirty patients with atrial septal defect(ASD)and twelve patients with ventricular septal defect (VSD)were studied by dynamic three-dimensional voxel imaging(3-D)to evaluate its diagnostic potential in clinics.The results showed that all the patients tolerated well,and forty-one patients were successfully studied.The defects were delin eated objectively from many unique directions and angles that would not be available with other current techniques,even simulated intraoperative visualization,in which the ASD were viewed from right atrium and VSD from right ventricle.3 D studies have been confirmed at operation in 25 patients.The site,size,geometry of defect and its relation to surrounding structures could be well appraised in their true form.of the 25 patients,3-D studies corrected 2 diagnoses in 2 patients and completed 2 diagnoses in another 2 patients made by multiple transesophageal echocardiography.
