Updates in the management of cranial dural arteriovenous fistula

What is it about?

Cranial Dural arteriovenous fistula (dAVF) account for approximately 10% of all intracranial vascular malformations. While they can benign lesions, the presence of retrograde venous drainage and cortical venous reflux makes the natural course of these lesions aggressive high risk of hemorrhage, neurological injury, and mortality. Endovascular treatment is often the first-line of treatment for dAVF. Both transarterial and transvenous approaches are used to cure dAVF. The selection of treatment approach depends on the angioarchitecture of the dAVF, the location, the direction of venous flow. Surgery and, to a lesser extent, stereotactic radiosurgery (SRS) are often utilized when endovascular approaches are impossible or unsuccessful.
