The accuracy of estimating intracranial pressure in brain tissue (ICPBT) via lumbar space
was investigated using preset pressure levels in the interval 0 to 600 mm H2O in patients
with communicating hydrocephalus. Lumbar space ICP correlated excellently to ICPBT,
demonstrated by a measured mean difference of 10 mm H2O (0.75 mm Hg) and a
regression coefficient of 0.98. The concurrence supports the lumbar puncture as an accurate
technique to determine ICP in patients with communicating CSF systems.
