目的:本研究旨在探讨影响儿童颅内蛛网膜囊肿(IACs)继发硬膜下出血(SDH)的因素。
方法:分析未破裂IAC患儿(IAC组)和IAC继发SDH患儿(IAC-SDH组)的数据。九个因素,性别,年龄,出生类型(阴道或剖腹产),症状,侧面(左,对,或中线),位置(时间或非时间),图像类型(I,II,或III),volume,和最大直径,被选中。IAC被归类为I型,II,和III根据其在计算机断层扫描图像上观察到的形态变化。
结果:有117名男孩(74.5%)和40名女孩(25.5%);144(91.7%)患者为IAC组,13(8.3%)为IAC-SDH组。左侧有85个(53.8%)IAC,右侧53(33.5%),20(12.7%)在中线区域,和91(58.0%)在时间区域。单因素分析显示年龄差异显著,出生类型,症状,囊肿位置,囊肿体积,囊肿最大直径(P<0.05)。使用合成少数群体过采样技术模型的Logistic回归表明,图像类型III和出生类型是影响IAC继发SDH的独立因素(β0=4.143;图像类型的β=-3.979;出生类型的β=-2.542),受试者工作特征曲线值下的代表面积为0.948(95%置信区间,0.898-0.997)。
结论:IAC在男孩中比在女孩中更常见。根据其在计算机断层扫描图像上的形态变化,可将其分为3组。图像类型III和剖宫产是影响IAC继发SDH的独立因素。
This study aimed to investigate factors that influence subdural haemorrhage (SDH) secondary to intracranial arachnoid cysts (IACs) in children.
Data of children with unruptured IACs (IAC group) and those with SDH secondary to IACs (IAC-SDH group) were analyzed. Nine factors, sex, age, birth type (vaginal or caesarean), symptoms, side (left, right, or midline), location (temporal or nontemporal), image type (I, II, or III), volume, and maximal diameter, were selected. IACs were classified as types I, II, and III according to their morphological changes observed on computed tomography images.
There were 117 boys (74.5%) and 40 girls (25.5%); 144 (91.7%) patients comprised the IAC group and 13 (8.3%) comprised the IAC-SDH group. There were 85 (53.8%) IACs on the left side, 53 (33.5%) on the right side, 20 (12.7%) in the midline region, and 91 (58.0%) in the temporal region. The univariate analysis showed significant differences in age, birth type, symptoms, cyst location, cyst volume, and cyst maximal diameter (P < 0.05) between the 2 groups. Logistic regression using the synthetic minority oversampling technique model showed that image type III and birth type were independent factors that influenced SDH secondary to IACs (β0 = 4.143; β for image type = -3.979; β for birth type = -2.542) and that the representative area under the receiver-operating characteristic curve value was 0.948 (95% confidence interval, 0.898-0.997).
IACs are more common in boys than in girls. They can be divided into 3 groups according to their morphological changes on computed tomography images. Image type III and caesarean delivery were independent factors that influenced SDH secondary to IACs.
