目的探讨超声诊断胎儿侧脑室轻度增宽的临床预后。方法回顾性分析71例妊娠期超声诊断的胎儿侧脑室10~12 mm病例,部分病例产前诊断胎儿染色体分析或核磁共振(MRI)检查,定期进行超声复查,并对所有病例进行随访。结果71例侧脑室增宽病例36例(50.70%)接受染色体检查,8例(11.27%)行无创DNA检测,44例中染色体异常1例(2.27%);28例在产前或产后进行了MRI的检查,均未见其他异常;65例(91.55%)正常分娩,其中63例(96.92%)随访正常。结论产前超声检查能够敏感地检出轻度侧脑室增宽的胎儿,孤立性轻度侧脑室增宽者染色体异常概率较低,预后较好。
Objective To investigate the clinical prognosis of fetal lateral ventricle with ultrasonography. Methods Retrospective analysis of 71 cases of fetal fetal ventricle 10 ~ 12 mm ultrasound diagnosis of pregnancy, some cases of prenatal diagnosis of fetal chromosomal analysis or MRI, regular ultrasound review, and all cases were followed up. Results Totally 71 cases (50.70%) were examined by chromosomal examination, 8 cases (11.27%) with noninvasive DNA test and 44 cases with chromosomal abnormalities in 1 case (2.27%). Twenty-eight cases were prenatal or postnatal No abnormalities were found in MRI. 65 cases (91.55%) had normal births, of which 63 (96.92%) were normal. Conclusions Prenatal ultrasound can detect fetuses with mild lateral ventricle enlargement sensitively. The probability of chromosomal abnormalities in isolated mild lateral ventricle enlargement is lower and the prognosis is better.
