Clinical experience on hematoma removal by means of craniotomy with small bone window resection in the treatment of hypertensive intracranial hematoma

Objective To explore the clinical efficacy of small bone window craniotomy in the treatment of hypertensive intracranial hematoma. Methods A total of 84 cases of patients with hypertensive intracranial hematoma were enrolled in this study from January 2009 to December 2012 and were divided into large trauma craniotomy group(42 cases) and small bone window craniotomy group(42 cases),were treated with large trauma craniotomy and small bone window craniotomy,respectively. Average expense,average hospitalization time,the rate of complications and short-term and long-term effects,hematoma clearance,rebleeding rate were compared. Results The patients' viability(ADL classification) 21days after operation was higher in small bone window craniotomy group compared with large trauma craniotomy group(P0.05).The residual hematoma was(9±1) ml in small bone window craniotomy group,while the residual hematoma was(15±3) ml in large trauma craniotomy group,the difference was significant(P0.05).2 cases(4.76%) in small bone window craniotomy group and 8 cases(19.05%) in large trauma craniotomy group had the incident of rebleeding,the difference of two groups was significant(P0.05). Conclusion Small bone window craniotomy is better than large trauma craniotomy in the treatment of hypertensive intracranial hematoma in the area of higher curative rates and lower rebleeding rates.
