A radioisotope scanning and clearance procedure has been developed for the postoperative assessment of third ventriculostomy patients. The patency of third ventriculostomy sites can be verified by this procedure, and the bulk flow clearance of CSF can be quantitated. 4 postoperstive third ventriculostomy patients have been evaluated by this procedure to date. In each case the third ventriculostomy site was shown to be patent. The bulk flow clearance of CSF ranged from 170 to 342 cm3/24 h. Comparison of these figures with estimates of CSF production suggests that the majority of CSF reabsorption in these patients occurs through the arachnoid villi.
已开发出一种放射性同位素扫描和清除程序，用于第三脑室造瘘术患者的术后评估。通过该程序可以验证第三脑室造瘘部位的通畅性，并对脑脊液的大量流动清除进行定量分析。迄今为止，已有4例术后第三脑室造瘘患者通过该程序进行了评估。在每例患者中，第三脑室造瘘部位均显示通畅。脑脊液的大量流动清除率在170至342 cm³/24小时之间。将这些数据与脑脊液生成量的估计值进行比较表明，这些患者的脑脊液大部分通过蛛网膜绒毛进行重吸收。
