Tentorial dural arteriovenous fistulas (DAVFs) are uncommon, complex fistulas located between the leaves of the tentorium cerebelli with a specific anatomic and clinical presentation characterized by high hemorrhagic risk. They have an extensive arterial supply and complex venous drainages, making them difficult to treat. There is recent literature favoring treatment through an endovascular transarterial route. The authors present an uncommon tentorial/ambient cistern region DAVF with feeders arising from the external and internal carotid arteries. The patient underwent a combined transarterial and transvenous approach with successful obliteration of the DAVF. The authors discuss the management challenges faced in this case.The video can be found here: https://youtu.be/VXDD8zUvsSQ.
小脑幕硬脑膜动静脉瘘（DAVF）是一种少见而复杂的瘘管，位于小脑幕的叶间，具有特定的解剖和临床表现，其特点是出血风险高。它们有广泛的动脉供应和复杂的静脉引流，因此治疗困难。最近有文献支持通过血管内经动脉途径进行治疗。作者介绍了一例罕见的小脑幕/环池区 DAVF，其供血动脉来自颈内动脉和颈外动脉。患者接受了经动脉和经静脉联合治疗，成功闭塞了 DAVF。作者讨论了该病例中面临的治疗挑战。视频可在此处查看：https://youtu.be/VXDD8zUvsSQ。
