Abstract
- We traced median nerve somatosensory evoked potential(SSEP) in 57 patients with putaminal hemorrhage from February, 1986 to January, 1991 for evaluation of relationship between SSEP findings and Glasgow outcome scale. 1) All patients with normal SSEP, prolonged central condution time and low ampulitude of cortical wave at affected side with small sized putaminal hemorrhage had good recovery to grade I. 2) Nine out of 25 patients with flat cortical wave of SSEP in small sized putaminal hemorrhage recovered to grade I. 3) All patients with moderate or large sized putaminal hemorrhage had flat cortical wave at affected side, none of them improved to grade I. It suggested that SSEP tracing in putaminal hemorrhage seemed to be valuable for evaluation of prognosis.
