The artery of Davidoff and Schechter is a dural branch of the posterior cerebral artery that can supply the meninges close to the falcotentorial junction. It is usually not identified on angiography except when enlarged in the setting of a dural AVF or meningioma. The impact on treatment of the artery of Davidoff and Schechter supply to a fistula is not well-described in the literature. Our retrospective analysis of patients with dural AVFs treated at the Toronto Western Hospital between 2006 and 2018 identified 6 patients with dural AVFs receiving supply from artery of Davidoff and Schechter (of a total of 173 patients with dural AVFs). All patients were initially treated by transarterial embolization using liquid embolic agents. Three patients required a second endovascular procedure partly due to residual supply from artery of Davidoff and Schechter, and in all cases, angiographic cure was obtained. The treatment approach, challenges encountered, and potential complications of treating such fistulas are described.
Davidoff 和 Schechter 动脉是大脑后动脉的硬脑膜分支，可以为靠近小脑幕缘的脑膜供血。除非在硬脑膜动静脉瘘或脑膜瘤的情况下增大，否则通常不会在血管造影中识别出它。文献中对 Davidoff 和 Schechter 动脉供应瘘管对治疗的影响描述得并不充分。我们对 2006 年至 2018 年在多伦多西部医院治疗的硬脑膜动静脉瘘患者进行了回顾性分析，确定了 6 例接受 Davidoff 和 Schechter 动脉供应的硬脑膜动静脉瘘患者（共 173 例硬脑膜动静脉瘘患者）。所有患者最初均采用液态栓塞剂进行经动脉栓塞治疗。由于仍有来自 Davidoff 和 Schechter 动脉的供血，3 名患者需要进行第二次血管内治疗，在所有情况下均获得了血管造影治愈。描述了这种瘘管的治疗方法、遇到的挑战和潜在的并发症。
