Vascular lesions with arteriovenous shunts are a heterogeneous group of diseases composed of three distinct pathological entities: adult type dural arteriovenous fistula, dural sinus malformations with arteriovenous shunts and juvenile type of dural arteriovenous fistula. We review the imaging and clinical features of a series of 51 patients, 48 with adult type dural arteriovenous fistula and 3 with dural sinus malformations. It is emphasized the dynamic nature of these lesions and the role of the venous drainage type in the adult type of dural AVF and veno-oclusive phenomena in the pediatric dural diseases as major determinants of the clinical presentation, prognosis and treatment decision.
伴有动静脉分流的血管病变是一组异质性疾病，由三种不同的病理实体组成：成人型硬脑膜动静脉瘘、伴有动静脉分流的硬脑膜窦畸形和青少年型硬脑膜动静脉瘘。我们回顾了51例患者的影像学和临床特征，其中48例为成人型硬脑膜动静脉瘘，3例为硬脑膜窦畸形。强调了这些病变的动态性质，以及静脉引流类型在成人型硬脑膜动静脉瘘中的作用，以及小儿硬脑膜疾病中的静脉闭塞现象，这些是临床表现、预后和治疗决策的主要决定因素。
