OBJECTIVE The aim of this study is to analyze the clinical effect of small bone-window craniotomy with microscope combined postoperative ICP monitoring, and further explore an appropriate treatment for HICH patients. METHODS One hundred fifty patients with HICH were selected according to inclusion and exclusion criteria and divided into 3 groups at random, 50 each group. Patients in 3 groups
were treated with conventional craniotomy, small bone-window craniotomy and small bone-window craniotomy combined ICP monitoring respectively. The surgical efficiency, treatment effect and outcomes were recorded and analyzed. RESULTS The intraoperative blood loss and operation time of small window groups were significantly less than that of conventional group, and the hematoma clearance rate in small window groups were significantly higher than in conventional group (P < 0.05). Compared with conventional group, the hospital stays and mannitol dose used were less in small window groups and least in small window combined ICP monitoring group (P < 0.05). The complication rate in small window combined ICP monitoring group was 10%, which was significantly lower than in conventional group (26%, P < 0.05), while no significant difference was found between small window group (18%) compared with the other 2 groups respectively (P > 0.05). The difference of morality rate between 3 groups wasn't significant (P > 0.05). Three treatment significantly increased the Barthel index score, and the improvement of small window combined ICP monitoring group was significantly higher than in other 2 groups respectively (P < 0.05), while the difference between this two groups wasn't significant (P > 0.05). CONCLUSION Small bone-window craniotomy is more efficient and convenient than conventional craniotomy in the treatment of HICH. In the meantime, small bone-window craniotomy simultaneous with ICP monitoring significantly improved clinical effect and treatment outcomes of HICH patients.
