目的：比较二维和三维两种不同超声模式对先天性心脏病合并感染性心内膜炎患者赘生物检出情况。方法选取确诊的63例先天性心脏病合并感染性心内膜炎患者为研究对象，均分别行二维及三维超声检查，观察赘生物检出情况。结果三维超声对先天性心脏病合并感染性心内膜炎患者赘生物检出率、赘生物个数整体检出率均高于二维超声（ P ＜0．05或 P ＜0．01）；三维超声对肺动脉瓣赘生物检出率及赘生物活动度检出率均高于二维超声（ P ＜0．05或 P ＜0．01）。结论三维超声对先天性心脏病合并感染性心内膜炎患者赘生物检出率高于二维超声，并可对不同活动度下赘生物的性质进行鉴别。%Objective To compare detection of neoplasm with 2D and 3D ultrasonography in patients with congenital heart disease complicated with infective endocarditis using two different two-dimensional and three-dimensional methods of ultrasound.Meth-ods Sixty-three confirmed cases of congenital heart disease complicated with infective endocarditis were chosen as the research objects and two-dimensional ultrasound and three-dimensional ultrasound were used to detect neoplasm.Results The neoplasm detection rate and number of neoplasm detection of three-dimensional ultrasound were higher than those of the two-dimensional( P <0.05 or P <0.01)and the detection rates of pulmonary artery neoplasms and neoplasm mobility of the three-dimensional ultrasound were higher than those of the two-dimensional ultrasound( P <0.05 or P <0.01).Conclusion The neoplasm detection rate of the three-dimensional ultrasound in patients with congenital heart disease complicated with infective endocarditis is higher than that of two-dimensional ultra-sonography and neoplasms of different mobilities can be differentiated.
