作者报道了4例脑积水儿童患者因分流管堵塞致脑脊液(CSF)水肿的病例。其中3例沿引流管有大面积的CSF水肿,尽管脑室压力增高,但无脑室扩大。 4例患儿均为男性(7～19岁)。例1为脊髓脑脊膜膨出,例2,软骨发育不全,例3,神经纤维瘤,例4,枕部脑膜膨出,均接受了脑室—腹腔分流术,脑室管末端侧孔长度为1.8～2.5cm。临床症状有头痛、呕吐及分流管皮下积液,出现于分流术后1～16月。患者入院后脑室内压力增加,脑脊液的细 The authors reported four cases of hydrocephalus in children with hydrocephalus due to shunt caused cerebrospinal fluid (CSF) edema cases. Three of them had extensive CSF edema along the drainage tube, and no ventricular enlargement occurred despite increased ventricular pressure. All 4 children were male (7-19 years old). Example 1 Spinal cord meningocele, case 2, achondroplasia, case 3, neurofibroma, case 4, occipital meningocele, were accepted ventricle - peritoneal shunt, ventricular end-tube side hole length of 1.8 ~ 2.5cm. Clinical symptoms of headache, vomiting and shunt subcutaneous effusion, shunt occurs in 1 to 16 months. Ventricular pressure increases after admission in patients with cerebrospinal fluid
