    Abstract:
    Recently, CT-guided stereotactic aspiration has been attempted as a useful method for hypertensive intracerebral hemorrhage. Since the CT scanner was introduced in our clinic, we have experienced 55 cases with hypertensive pontine hemorrhage. We carried out stereotactic aspiration in nine cases consisting of four men and five women, ranging in age from 34 to 66 years. Operation was performed on between 4 and 22 days after the hemorrhage (mean 7.7 days). On the other hand, 46 cases were conservatively treated. They consisted of 31 men and 15 women, aged from 31 to 79 years, with a mean age of 55.5 years. The purpose of this study is to review the outcome at three months after the onset, and then to evaluate the clinical value of this method for hypertensive pontine hemorrhage. We have analyzed the outcome from the viewpoint of consciousness level, CT classification, and maximum transverse hematoma diameter on CT scan. In the present study, there was a statistically significant correlation between consciousness level and outcome in the conservative group. The outcome in the operated-on group tended to be superior to that in the conservatively treated group. Particularly, in cases of Japan Coma Scale 10 to 100, functional favorable effects were considered to be obtained by stereotactic aspiration. According to CT classification, operation was considered to have exerted functionally favorable effects on unilateral basis-tegmentum type and bilateral tegmentum type. The conservatively treated group showed a statistically significantly correlation between maximum transverse hematoma diameter and outcome.(ABSTRACT TRUNCATED AT 250 WORDS)
