The application of transcranial Doppler ultrasound to the diagnosis of blocked ventriculo-peritoneal shunts was studied in 63 children. Thirty two of these required shunt revision, whereas in 31 children symptoms resolved without surgery. The group of children requiring shunt revision had a significantly higher mean Gosling pulsatility index, than both the group of children whose symptoms resolved and a group of age-matched controls (p less than 0.001). Those with a raised pulsatility index were more likely to have higher intracranial pressure. There was no correlation between CT scan changes and the pulsatility index.
对63名儿童进行了经颅多普勒超声在诊断阻塞性脑室 - 腹腔分流术中的应用研究。其中32名儿童需要进行分流术修正,而31名儿童未经手术症状即得到缓解。需要进行分流术修正的儿童组的平均戈斯林搏动指数,显著高于症状缓解的儿童组和年龄匹配的对照组(p<0.001)。搏动指数升高的儿童更有可能颅内压升高。CT扫描变化与搏动指数之间无相关性。
