Abstract
Stereotactic hematoma evacuation (SHE) has been reported to reduce mortality and to improve functional outcome in patients with spontaneous putaminal hemorrhage. Stereotactic hematoma evacuation has not been widely accepted, however, as a standard therapy because its effect on functional outcome has been regarded as marginal and insufficient to justify the costs of surgery. We reassessed the value of SHE by analyzing its impact on chronic-period medical costs based on an original randomized study carried out by us. In total, 490 patients were entered into the study. The degree of neurologic severity was defined on admission according to the neurologic grades (NGs) ranging from NG1 to NG5, adopted by the Japanese Cooperative Study on Stroke Surgery. The NG2 and 3 patients were randomized into 2 groups with different treatment protocols (group I, SHE; group II, conservative treatment). On the other hand, the NG1, 4, and 5 patients were excluded from the randomization because a large-scale retrospective study in Japan had revealed that surgical treatment in patients assigned to these NG grades does not improve functional outcome. Among the 490 patients, 248 were excluded and 242 were randomized strictly. The latter patients compri...Continue Reading
