摘要:目的:探討慢性硬膜下血腫(chronic subdural hematoma, CSDH)鉆孔沖洗引流術后的復發因素。方法：回顧性分析165例CSDH鉆孔沖洗+閉式引流術的治療效果,并結合患者年齡、術后引流量、血腫腔是否有間隔、血腫厚度、引流管安放方向等因素進行相關分析。結果:本組治愈151例,血腫復發14例。〖HTH〗結論〖HTSS〗:患者年齡、術后引流量、血腫腔是否有間隔、血腫厚度、引流管安放方向是影響復發的主要因素。Abstract: Objective: To explore the related factors of recurrence of chronic subdural hematoma after burr hole drainage.Methods:The related aspects that affected the recurrence in 165 cases with chronic subdural hematomas after burr hole drainage were reviewed,and patient’s age,drainage volume,thickness of hematoma, septal hematoma cavity and direction of drain pipe were evaluated.Results:Clinical outcomes were satisfactory.151 patients completely recovered after burr hole drainage,there were 14 patients with hematoma recurrence. Conclusion : Age, drainage volume, thickness of hematoma, septal hematoma cavity and direction of drain pipe would affect the prognosis.
