From January 2000 to December 2006, 78 hypertensive patients with intracerebral hemorrhage(80～130 ml)underwent minimally invasive surgery(n=41)or small bone window craniotomy(n=37). Neurological deficit scores and mortality were estimated to evaluate the therapeutic efficacy among those two group patients. The success rate was significantly higher in the micro-invasive surgery group than the small bone window craniotomy group(P＜0. 05). However, no significantly lower mortality was detected in the micro-invasive surgery group(P＞0. 05). In summary, micro-invasive surgery may reduce the mortality, largely increase the success rate of treatment, and improve patients' quality of life.
