【摘要】：目的探讨MRI对超声发现侧脑室增宽胎儿的诊断价值及出生后的预后评价。方法选取超声发现胎儿侧脑室增宽或疑似合并其他神经系统疾病、接受产前MR检查的孕妇124例,比较MRI与超声的诊断结果并评估患儿出生后神经系统发育情况。结果 124例孕妇中,MRI诊断胎儿侧脑室增宽且合并其他神经系统疾病18例,包括确诊超声疑似诊断6例,诊断与超声结果不一致12例。MRI随访单纯性侧脑室增宽的106胎胎儿:11胎终止妊娠,95胎分娩。存活婴幼儿中45例复查头MRI,9例诊断为神经系统疾病,侧脑室宽度12~15 mm亚组发生率高于10~12 mm亚组(42.11%vs 3.85%,P0.01),双侧脑室不对称增宽亚组高于对称性增宽亚组(54.55%vs 11.76%,P0.05)。侧脑室宽度10~12mm亚组中96.15%(25/26)患儿出生后预后良好。结论 MRI与超声有效结合可以提高产前诊断率,单纯性侧脑室宽度10~12 mm的胎儿预后良好;对于12~15 mm及双侧脑室不对称增宽的胎儿,应重视出生后远期随访。
[Abstract]:Objective to investigate the value of MRI in the diagnosis of fetus with lateral ventricular enlargement and the evaluation of prognosis after birth. Methods 124 pregnant women with fetal lateral ventricular enlargement or suspected complicated with other neurological diseases were selected for prenatal Mr examination. Results in 124 pregnant women, 18 cases of fetal ventricular enlargement and other neurological diseases were diagnosed, including 6 cases of suspected diagnosis by ultrasonography. MRI follow-up of 106 fetuses with simple lateral ventricular enlargement terminated pregnancy at the end of pregnancy and 95 births. Among the 45 surviving infants, 9 were diagnosed as neurological diseases. The incidence of lateral ventricular width of 12 ~ 15 mm subgroup was higher than that of 10 卤12 mm subgroup (42.11 vs 3.85) P0.01a, bilateral ventricular asymmetry widening subgroup was higher than that of symmetrical ventricular widening subgroup (54.55 vs 11.76% P0.05), and that of 1012mm subgroup of lateral ventricular width 1012mm had a good prognosis after birth. Conclusion MRI and ultrasound have a good prognosis after birth. The combination of effect can improve the rate of prenatal diagnosis, The prognosis of the fetus with simple lateral ventricular width of 10 ~ 12 mm was good, and the long-term follow-up should be paid attention to for the fetus with 1215 mm or asymmetric enlargement of bilateral ventricle.
