为了解孕期、分娩期及产后因素与脑性瘫痪(CP)的关系,作者对40例CP 患者的MR 检查结果进行了回顾性研究。40例患者年龄1～41岁,所有患者均用T_1和T_2加权相应矢状面和轴面扫描,重点观察脑各部结构有无发育异常或继发性改变,有无脑实质囊腔、脑积水及脑室形态异常等。如果皮层异常增厚,相邻白质缩小,缺乏分支,异常脑实质下方的脑室轻度扩大,则诊断为多小脑回畸形(polymicrogyria)。如果脑灰质裂一直伸延到侧脑室,则诊断为脑裂畸形。(schizencephaly)。40例中11例(27%)为早产儿(孕36周以前出生),29例(73%)为足月产儿。预产期的定义为产前产后各两周。围产期窒息包括胎儿宫内窘迫和新生儿呼吸窘迫。脑室周围自质软化(PVL)指单独存在的脑室周围白质损害而不伴有皮层、皮
To understand the relationship between pregnancy, childbirth and postpartum factors and cerebral palsy (CP), the authors retrospectively reviewed the MR findings of 40 CP patients. 40 patients aged 1 to 41 years, all patients were T_1 and T_2 weighted corresponding sagittal and axial scanning, focusing on the observation of various parts of the brain structure or non-developmental or secondary changes, with or without parenchymal cysts, brain volume Abnormal water and ventricular morphology. If the cortex is abnormally thickening, the adjacent white matter is reduced, the branch is absent, and the ventricles under the abnormal parenchyma are slightly enlarged, the polymicrogyria is diagnosed. If the gray matter crack extending to the lateral ventricle, then diagnosed as schizencephaly. (schizencephaly). Eleven patients (27%) were premature (born before the age of 36 weeks) and 29 (73%) were full-term infants in 40 cases. Maternity is defined as prenatal and postnatal two weeks. Perinatal asphyxia includes fetal distress and neonatal respiratory distress. Periventricular self-softening (PVL) refers to the presence of solitary periventricular white matter damage without cortex, skin
