A cisternographic pattern of subarachnoid block with transient or no ventricular radiopharmaceutical reflux was observed in 52% of 105 patients with partial extra-arachnoid injections or postinjection leakage of CSF or both at the lumbar puncture site. In several patients, adequate repeat studies demonstrated considerably different CSF flow patterns. This block pattern was seen in only 11% of 217 patients with adequate intrathecal injections. Lumbar CSF leakage may alter the pattern seen on a cisternographic study and, if present, the study should be interpreted with caution.
在105例腰椎穿刺部位存在部分蛛网膜下腔注射、脑脊液注射后渗漏或两者皆有的患者中，52%观察到蛛网膜下腔阻滞的脑池造影模式，伴有短暂性或无脑室放射性药物反流。在数例患者中，充分的重复检查显示脑脊液流动模式有显著差异。在217例鞘内注射充分的患者中，仅11%出现这种阻滞模式。腰椎脑脊液渗漏可能会改变脑池造影检查所见的模式，若存在这种情况，对该检查结果的解读应谨慎。
