中文摘要：

目的探讨硬脑膜动静脉瘘（DAVF）颅内出血的相关影响因素。方法回顾性分析北京天坛医院1996至2006年144例DAVF住院病人的性别、年龄、瘘口流速、血供来源、病变部位以及静脉引流方式对颅内出血的影响。结果DAVF颅内出血的单因素分析提示性别、病变部位、静脉引流方式对颅内出血的发生差异有统计学意义（P〈0．05）；DAVF颅内出血的Logistic回归分析提示静脉引流方式对颅内出血的发生差异有统计学意义（P〈0．05）。结论静脉引流方式是DAVF颅内出血风险最重要的影响因素，性别和病变部位对评估DAVF颅内出血风险有一定的意义。

英文摘要：

Objective To discuss the relevant predicative factors of dural arteriovenous fistula （dAVF） in intraeranial hemorrhage. Methods A total of 144 consecutive patients with dAVFs were recruited for a retrospective analysis from 1996 to 2006. The relevant factors of gender, age, fistula flow rate, arterial supply, lesion and venous drainage pattern were analyzed to evaluate the outcome of intracranial hemorrhage. Results Univariate analysis showed that gender, lesion and venous drainage pattern were statistical significant for intracranial hemorrhage of DAVF （ P 〈 0. 05 ） . However, only venous drainage pattern was significant in the predication of intracranial hemorrhage （ P 〈 0. 05 ）. Conclusion Only venous drainage pattern is significant in the predication of dural arteriovenous fistulas in iutracranial hemorrhage. Both gender and lesion may be confounding factors.
