Dural arteriovenous fistulas are abnormal communications, within the dural leaflets, between meningeal arteries and dural venous sinuses and/or subarachnoid veins. Although many fistulas remain clinically silent and do not require treatment, presence of cortical venous reflux, intracranial bleed, and intolerable symptoms are the main indications for treatment. A thorough understanding of the natural history is of prime importance in the decision making and management of these lesions. In this chapter we discuss the epidemiology and natural history of intracranial dural arteriovenous fistulae.
硬脑膜动静脉瘘是指在硬脑膜叶内，脑膜动脉与硬脑膜静脉窦和/或蛛网膜下静脉之间的异常交通。尽管许多瘘在临床上并无症状，无需治疗，但存在皮质静脉回流、颅内出血及难以耐受的症状是治疗的主要指征。全面了解其自然病史对于这些病变的决策和管理至关重要。在本章中，我们将讨论颅内硬脑膜动静脉瘘的流行病学和自然病史。
