To study the findings in radionuclide cisternography in patients with obstructive hydrocephalus following third ventriculostomy.
Lumbar radionuclide cisternography was performed in 15 patients with obstructive hydro- cephalus before and after third ventriculostomy.
The postoperative cisternography identified radiopharmaceutical reflux into the lateral cerebral ventricles with delayed clearance for 24 h, similar to the findings by cisternography of communicating hydrocephalus.
The cause of ventricular radiopharmaceutical reflux is not yet understood, possibly in association with the reversal of normal cerebrospinal fluid flow though the fenestration on the third ventrical floor.
研究梗阻性脑积水患者在第三脑室造瘘术后行放射性核素脑池造影的结果。
对15例梗阻性脑积水患者在第三脑室造瘘术前和术后进行腰段放射性核素脑池造影。
术后脑池造影显示放射性药物反流至侧脑室且清除延迟24小时，这与交通性脑积水脑池造影的结果相似。
脑室放射性药物反流的原因尚不清楚，可能与通过第三脑室底部开窗处正常脑脊液流动的逆转有关。
