Intracranial dural arteriovenous fistulae (DAVF) are pathologic arteriovenous shunts between meningeal arteries and dural venous sinuses or veins. They account for approximately 10% to 15% of all intracranial vascular malformations and are most common in middle-aged patients. DAVF are the most common vascular cause of pulsatile tinnitus. Digital subtraction angiography remains the gold standard for diagnosing these lesions. The pattern of venous drainage determines the type of DAVF and their risk for hemorrhage. Endovascular treatment has become a first-line option for their management. This article describes the natural history, clinical presentation, classification, imaging features, and management options of intracranial DAVF.
颅内硬脑膜动静脉瘘（DAVF）是脑膜动脉与硬脑膜静脉窦或静脉之间的病理性动静脉分流。它们约占所有颅内血管畸形的10%至15%，在中年患者中最为常见。DAVF是搏动性耳鸣最常见的血管原因。数字减影血管造影仍然是诊断这些病变的金标准。静脉引流模式决定了DAVF的类型及其出血风险。血管内治疗已成为其治疗的一线选择。本文描述了颅内DAVF的自然病程、临床表现、分类、影像学特征和治疗选择。
