Abstract

Intracranial pressure (ICP) was monitored in a 12-year-old child before and after closure of a large, skin-covered meningomyelocele. Significant cerebrospinal fluid pulse pressure augmentation was observed over a spectrum of pressures following sac closure. Linear regression analysis was done to define pulse pressure-ICP relationships before and after surgery, and a significant increase in the regression slope was noted postoperatively. It is suggested that the unoperated meningomyelocele defect served as a shock absorber to dampen the intracranial pulse pressure. Meningomyelocele closure removes this shock absorber effect, resulting in pulse pressure augmentation.

脑脊膜膨出闭合对颅内脉压的影响。
我们监测了一名12岁儿童的颅内压(ICP),在闭合一个大的,皮肤覆盖的脑膜脊膜膨出之前和之后。在囊闭合后的压力谱上观察到显著的脑脊液脉冲压力增加。通过线性回归分析确定术前和术后脉搏压力- icp关系,发现术后回归斜率显著增加。提示未手术的脑脊膜膨出缺损可作为减震器,抑制颅内脉压。脑膜脊膜膨出闭合消除了这种减震器作用,导致脉压增高。
