目的 :探讨婴儿痉挛症 ( IS)的病因、头颅 CT改变及二者之间的关系。方法 :对2 0 6例 IS的病因及头颅 CT进行分析。结果 :IS病因中产前因素占 5 6.8% ,围产期因素占2 9.6% ,产后因素、原发性各占 6.8%。 1 70例头颅 CT中 ,异常率为 71 .8% ,其中脑萎缩占49.4% ,结节性硬化占 9.4% ,低密度影及脑软化占 6.5 % ;先天性脑发育不良、缺氧缺血或出血性脑病是脑萎缩的主要原因。结论 :IS主要由产前及围产期因素引起 ,头颅 CT异常率占 71 .7% ,异常 CT主要由先天性脑发育不良、产后脑缺氧等引起
Objective: To investigate the etiology of infantile spasms (IS), the changes of cranial CT and the relationship between the two. Methods: The etiology and head CT of 206 cases of IS were analyzed. Results: The causes of IS were 56.8% of prenatal factors, 29.6% of perinatal factors and 6.8% of postpartum factors. 1 70 cases of cranial CT, the abnormal rate was 71.8%, of which brain atrophy accounted for 49.4%, 9.4% of tuberous sclerosis, low density and cerebral softening accounted for 6.5%; congenital brain dysplasia, hypoxic-ischemic Or hemorrhagic encephalopathy is the main cause of brain atrophy. Conclusion: IS is mainly caused by prenatal and perinatal factors. The abnormal rate of cranial CT accounts for 71.7%. Abnormal CT is mainly caused by congenital brain dysplasia and postpartum cerebral hypoxia
