摘要
目的探讨产前超声对胎儿胼胝体发育不全(agenesis of the corpus callosum,ACC)的诊断价值及临床意义。方法对超声诊断胼胝体发育不全的17例胎儿,结合核磁共振(MRI)、出生后或引产结果进行分析比较。结果 17例超声诊断完全型ACC 6例,部分型ACC 11例;2例完全型ACC及1例部分型ACC的超声结论与MRI检查结果一致,5例完全型ACC及7例部分型ACC与引产或出生后结果一致;13例行染色体检查,4例染色体异常;9例合并其它畸形或多种畸形并存。结论产前超声检查对诊断胎儿ACC特别是完全型ACC具有一定的优势,胎儿ACC常合并其它畸形,MRI是诊断胎儿ACC的必要手段。
Objective To evaluate the clinical accuracy of antenatal ultrasonic（US） diagnosis of fetal agenesis of the corpus callosum（ACC）.Methods The data of 17 cases of suspected fetal ACC in prenatal US screening were compared with the results of fetal MRI after birth or induced labor.Results Of the 17 cases,6 cases were complete ACC and 11 cases were partial ACC.The ultrasonic results of 2 cases with complete ACC and one case with partial ACC were consistent with the diagnostic results of MRI.The US diagnosis result of 1 complete ACC cases and 7 partial ACC cases were consistent with the results found after induced labor or after birth.Thirteen cases received chromosomal screening,of which 4 cases had chromosomal abnormality,and 9 cases had another malformation or multiple malformations.Conclusion Prenatal ultrasonography has significant advantages in accurate diagnosis of fetal ACC,especially complete ACC.Since fetal ACC is often associated with other parts of malformation,MRI is also a necessary method of accurate diagnosis of fetal ACC.
