目的：探讨应用高位钻孔持续冲洗引流与微创穿刺引流治疗老年慢性硬膜下血肿的疗效及并发症。方法回顾性分析2009年1月至2012年1月分别应用高位钻孔持续冲洗引流术（实验组，159例）及微创穿刺引流术（对照组，145例）治疗患者的临床资料，评价两组患者的临床疗效及手术并发症。结果两组患者入院及出院时临床神经功能缺损程度评分比较差异未见统计学意义（P >0.05）；但两组入院及出院时比较差异有统计学意义（P 0. 05),but the difference of clinical nerve deficiency scale of each group between admission and discharge was significant(P <0. 05). The cure rate of both groups was above 90% . Residual hematoma between the control group and the ex-perimental group occurred 22 cases(15. 2% )and 6 cases(3. 8% )respectively,intracranial pneumatosis on third day after surgery occurred 20 cases(13. 8% )and 7 cases(4. 4% )respectively,intracranial hematoma after surgery occurred 15 cases(10. 3% )and 5 cases(3. 1% )respectively,intraoperative brain injury occurred 7 cases(4. 8% )and 0 case(0% )respectively,these complica-tions had significant differences between the two groups(P 0. 05). Conclusion High drilling hole irrigation-drainage and microinvasive craniopuncture have comfirmed effect,but high drilling hole irrigation-drainage has few complications and high operation safety,and is worthy to be popularized.
