ABSTRACT |
With the radioactivity clearance curve of 99mTc-DTPA which was injected into the flusing device, the authors measured cerebrospinal fluid(CSF) flow rate through the shunt tube.
The CSF flow rates in resting state in control group and malfunction group were considerably variable and there was no difference of CSF flow rates between the two groups. The significance, advantages, and problems of CSF flow rate measurement were discussed. The changes of CSF flow rate according to physiologic and pathologic fluctuation of intracranial pressure(ICP) should be taken into consideration for a valuable clinical application of this study. |
Key Words:
