Acquired arteriovenous malformations, such as is the case with dural arteriovenous fistulae (DAVF), are the consequence of a pathological new arterial ingrowth into venous spaces that reaches directly the venous lumen, without interposition of a capillary network, thereby creating an AV-shunt.The following concise text will provide elements in regards to diagnosis, indication for treatment discussion and choice of endovascular treatment (EVT) method.

Endovascular Treatment for Tentorial Dural Arteriovenous Fistulas: A Retrospective Single-Center Study.

Department of Neurovascular Center, Changhai Hospital, Naval Medical University, Shanghai, China.
Background And Purpose: Current evidence suggests that tentorial dural arteriovenous fistulas with endovascular treatment offer a high rate of occlusion and reduced procedural risks. Here we report the clinical and angiographic outcomes in patients with tentorial dural arteriovenous fistulas who underwent endovascular treatment as first-line treatment.
Materials And Methods: A retrospective analysis was conducted on 83 patients with tentorial dural arteriovenous fistulas treated at our center from April 2009 to November 2023 using endovascular treatment.

Spinal dural arteriovenous fistulas (sDAVFs) are rather uncommon lesions of the spine. In sDAVFs, which represent the most frequent form of vascular malformations of the spine, operative treatment remains the most common treatment modality. In operative surgery, visualization and pathology detection have a key impact on the results of the neurosurgical treatment of an sDAVF.

We report the management of a convexity dural arteriovenous fistula (dAVF) in an uncommon anterior superior sagittal sinus (SSS) location. This was a high-risk Cognard IIa+b dAVF, which is notoriously complex to treat. Endoscopic management alone for complex SSS dAVFs is challenging due to the often bilateral arterial supply to the fistula, as demonstrated in this case.

Study Design: Systematic Review and Meta-analysis.
Objective: This study aims to compare the efficacy and safety of surgical and endovascular treatments for SDAVFs.
Summary Of Background Data: Spinal dural arteriovenous fistulas (SDAVFs) result from an abnormal connection between the radiculomeningeal artery and the radicular vein, leading to venous hypertension and potential neurological damage.
