摘　　要：目的探讨先天性膝关节脱位(CKD)的产前超声图像特征及结局分析。方法回顾性分析12例CKD胎儿的临床及超声资料,分析总结其超声特征,并随访其结局。结果CKD产前超声表现为患侧膝关节屈曲方向异常,即屈曲方向与足尖指向相反,呈向心性屈曲。75%(9/12)与多发畸形合并存在,于孕13^(+3)~24周诊断;25%(3/12)为孤立性,于孕36^(+3)周或出生后诊断。产前超声诊断正确率为83.33%(10/12)。结论CKD具有特征性产前超声表现,其妊娠结局与是否合并多发畸形相关。Objective To investigate the prenatal ultrasonic features and clinical outcome of congenital knee dislocation(CKD).Methods A retrospective analysis of 12 CKD cases were performed,including clinical data,prenatal ultrasonic features and outcomes.Results It revealed the abnormal knee flexion in the direction of the affected side by prenatal ultrasound,which was centripetal flexion with opposite direction to the toe point.75%(9/12)were associated with multiple malformations and could be diagnosed at 13^(+3)~24 weeks of gestation,while 25%(3/12)were isolated and diagnosed at 36^(+3) weeks of gestation or postnatal period.83.33%(10/12)of cases were accurately diagnosed in the prenatal period.Conclusions The CKD has typical ultrasonic image features.The pregnant outcome is associated with the accompanied malformations.
