影响新生儿侧脑室旁囊肿超声分型的相关因素研究

Study on related factors affecting classification in neonatal lateral ventricular cysts by ultrasonography

目的探讨新生儿侧脑室旁囊肿超声分型的相关影响因素。方法回顾性分析224例侧脑室旁囊肿患儿的颅脑超声和MRI检查图像,根据超声图像中囊肿的发生位置,将其分为前角前囊肿、体旁型囊肿及Connatal囊肿,分析囊肿分型与年龄、性别、缺血、出血、感染及低体质量因素的相关性。结果单因素分析显示与侧脑室旁囊肿超声分型相关的影响因素有缺血、感染及低体质量因素(χ2=89.022、58.018、18.257,均P<0.01)。多因素分析显示:前角前囊肿与缺血因素有关,体旁型囊肿与感染因素有关,Connatal囊肿则与低体质量因素有关。结论缺血、感染及低体质量因素分别影响不同类型新生儿侧脑室旁囊肿的形成,缺血可能为前角前囊肿的危险因素,感染可能为体旁型囊肿的危险因素,低体质量则可能为Connatal囊肿的危险因素。

Objective To explore related factors affecting classification in neonatal lateral ventricular cysts by ultrasonography. Methods Both ultrasound and MRI imaging data of 224 cases of lateral ventricle cyst were enrolled and analyzed retrospectively.According to the location,the cysts were divided into three types：anterior horn before cyst,para body cyst and Connatal cyst.The correlation between the cyst type and factors including age,gender,ischemia,hemorrhage,infection and low weight were analyzed. Results Single factor analysis showed that ischemia,infection and low body mass were related factors for lateral ventricle cyst（χ2=89.022,58.018,18.257,all P〈0.01）.Multivariate analysis showed that the ischemia related to the anterior horn cyst,the infection related to the para body cyst,while the low body mass related to the Connatal cyst. Conclusion Ischemia,infection and low body mass related to different types of neonatal periventricular cysts.Ischemia may be the risk factors of anterior horn before cyst,infection may related to the para body type cyst,low body mass may be one of the risk factors for Connatal cyst.
