【摘要】：目的:探讨胎儿主-肺动脉间隔缺损的超声声像图特征,提高超声对此病的产前诊断水平。方法:对2010年1月—2013年12月经我院产前超声诊断为胎儿主-肺动脉间隔缺损的5例超声检查资料进行回顾性分析,总结主-肺动脉间隔缺损的超声特征。结果:产前超声诊断为胎儿主-肺动脉间隔缺损的病例共5例,按Richardson分型法,Ⅰ型4例,Ⅱ型1例;缺损大小为0.17~4.0 mm。其中1例合并有室间隔缺损。声像图主要表现在三血管观上可见主动脉与肺动脉之间出现回声中断,范围大小不等,缺损呈窗形或弧形。CDFI在缺损处可探及肺动脉向主动脉分流信号。结论:胎儿主-肺动脉间隔缺损具有特征性声像图,产前超声能够显示主-肺动脉间隔缺损的位置、大小及血流动力学改变等情况,是产前首选的检查方法。
[Abstract]:Objective: to investigate the ultrasonographic features of fetal aorta septal defect (MPASD) and to improve the prenatal diagnosis of the disease. Methods: from January 2010 to December 2013, the ultrasonographic data of 5 cases of fetal aortopulmonary septal defect diagnosed by prenatal ultrasound from January 2010 to December 2013 were analyzed retrospectively. Results: according to Richardson's classification, there were 5 cases of fetal aortopulmonary septal defect diagnosed by prenatal ultrasound, 4 cases of type 鈪，
