Abstract

Objective : The purpose of this study is to review our experience with spontaneous thalamic hemorrhage. Clinical outcome of patients was brought about by comparing stereotactic aspiration and conservative medical therapy. Methods : The study consists of seventy-three cases with spontaneous thalamic hemorrhage which were treated from the period of Jan. 1993 to Dec. 1999. Thirty-eighty patients were treated with computed tomography (CT) guided stereotactic aspiration and thirty-five patients were treated conservatively. We compared the factors affecting treatment and the factors are as follows : age & sex, conscious level on admission, hematoma volume, hematoma sites, presence of ventricular penetration. Results : The results in the thirty eight stereotactic aspirated cases for the 6 months from oneset are as follows : good recovery or moderate disability in 43%, severe disability in 32%, vegitative state in 11%, dead in 13% respectively. The clinical result was more favorable in stereotactic aspiration, with 11-30cc hematoma volume, extend to internal capsule of hematoma, poor conscious level on admission than conservative medical therapy. But age & sex, conscious level on admission, presence of ventricular penetration were not influential in the statistical outcome between stereotactic aspiration and conservative medical therapy. Conclusion : Treatment modality of spontaneous thalamic hemorrhage is still controversial. But stereotactic aspiration is more recommended for improvement therapeutic results than conservative treatment or open craniotomy in case of 11-30cc hematoma volume, extend to internal capsule of hematoma and poor conscious level on admission.
