目的探讨胎儿单纯性侧脑室扩张的MRI诊断及临床预后分析,为产前诊断及临床处理提供可靠依据。方法搜集我院经US筛查、产前MRI诊断为单纯性侧脑室扩张的胎儿98例。按照扩张程度分为3组,A组:宽度为10.0~12.0mm,68例,B组:宽度为12.1~15.0mm,22例,C组:宽度为>15.0mm,8例。98例胎儿出生后分别于3、6、12、18月定期随访(早产儿矫正月龄后随访),并用Gesell发育量表评估神经行为发育情况,与50例对照组正常胎儿同期神经行为发育情况进行比较,得出结论。结果 A组出生后4次随访结果与正常组对照P>0.05;B组出生后3、6个月随访结果与正常组对照P<0.05,12、18个月后随访结果与正常组对照P>0.05;C组出生后前4次随访评估结果与对照组比较P<0.05。结论胎儿单纯性侧脑室扩张宽度≤12.0mm时,临床可无须处理;扩张宽度介于12.1mm~15.0mm时,临床密切随访,出生后进行针对性康复训练;扩张宽度>1 5.0mm时,应引起足够的重视,尽早干预,以期改善预后。
Objective To investigate the MRI diagnosis and clinical prognosis of simple unilateral ventricular dilatation in fetuses and provide a reliable basis for prenatal diagnosis and clinical treatment. Methods We collected 98 cases of fetuses diagnosed as simple lateral ventricle dilatation by US screening and prenatal MRI. According to the degree of expansion, the patients were divided into 3 groups: group A: width was 10.0-12.0mm, 68 cases; group B: width was 12.1-15.0mm; group C: width was> 15.0mm; 98 fetuses were followed up regularly at March, June, December and December (after follow-up of premature infant corrected for age), and the neurological and behavioral development was assessed by Gesell developmental scale. The neurobehavioral development of the normal fetus in 50 cases To compare, draw conclusions. Results The results of 4 follow-up after birth in group A were compared with those in normal group (P> 0.05). The follow-up results in group B at 3 and 6 months after birth were compared with those in normal group (P <0.05). The follow-up results at 12, 0.05; C group after birth, the first 4 follow-up assessment results compared with the control group P <0.05. Conclusions Fetal simple lateral ventricle dilation width ≤ 12.0mm, the clinical treatment may not be required; when the dilatation width ranges from 12.1mm to 15.0mm, clinical follow-up and targeted rehabilitation training after birth; Aroused enough attention, as soon as possible intervention, with a view to improving the prognosis.
