摘要
摘要目的通过胎儿畸形的超声筛查,尤其是III级筛查探讨超声检测胎儿肢体末端结构的诊断思路.方法制定胎儿肢体末端超声扫查的切面图,按此标准在日常工作的超声III级筛查中针对孕１８—２４孕周胎儿进行肢体末端结构筛查.结果对１７０００例胎儿III级筛查中,发现胎儿肢体末端结构异常的病例５２例、７３处,其中单纯性指趾异常１７例,其余为复合性胎儿畸形.结论胎儿超声III级筛查中虽然未要求对指趾异常的筛查,但通过对指趾的超声扫查切面的增多,能够提高胎儿肢体末端结构异常的检出率,从而最大程度地降低因漏诊而引起的投诉.关键词超声筛查;胎儿肢体末端结构;三维成像;诊断思路AbstractObjectivesWithultrasoundscreening,especiallygradeIIIscreening,twodimensionalandthree－dimensionalultrasoundimagingwereconductedindetectingfetalextremities．MethodsWithourestablishedstandardultrasoundsectionsofthefetalextremities,routinegradeIIIscreeningtosecondtrimesterofpregnancywereconducted．ResultsAmong１７０００gradeIIIscreeningpregnanciesenrolledinthisstudy,２１placesof５２anomalouscasesweredetectedbyultrasoundscan．１７werejustfingerabnormities,otherswerecomplexabnormities．ConclusionFetalextremitiesscreeningwerenotrequirementofgradeIIIscreening,butmoreultrasoundsectionsofthefetalextremitieswouldimprovetherelevanceratioofthedeformitiesandextremelyreducecomplainsofmisseddiagＧnosis．KeywordsUltrasoundscreening;Fetalstructuralextremities;Three－dimensionalultrasoundimaging;Diagnosis中图分类号R４４５文献标识码B文章编号１００８－６３１５(２０１５)１０－００３５－０２
