目的探讨三维超声在诊断共同房室瓣Rastelli分型中的应用价值。方法回顾17例完全型房室间隔缺损的二维与三维超声检查,对照手术结果,分析两种检查方法在诊断共同房室瓣Rastelli分型中的差异。结果手术结果13例Rastelli A型,2例B型,2例C型,三维超声检查符合率100%,二维超声误诊5例,符合率70.6%,两者差异有统计学意义。结论三维超声在诊断共同房室瓣Rastelli分型中可为临床提供更立体、更客观、更准确的影像学信息,是二维超声的有益补充。
Objective To investigate the value of three-dimensional ultrasonography in the diagnosis of Rastelli’s classification of common atrioventricular valve. Methods Two-dimensional and three-dimensional ultrasonography of 17 cases of complete atrioventricular septal defect were retrospectively analyzed. The differences between the two methods in the diagnosis of common atrioventricular valve Rastelli type were analyzed. Results The operative results included 13 cases of Rastelli A type, 2 cases of B type and 2 cases of C type. The coincidence rate was 100% by three-dimensional ultrasonography and 5 cases by two-dimensional ultrasonography. The coincidence rate was 70.6%. The difference was statistically significant. Conclusion Three-dimensional ultrasound can provide more stereoscopic, objective and accurate radiographic information in the diagnosis of common atrioventricular valve Rastelli classification, which is a useful complement to two-dimensional ultrasound.
