Endovascular Management of Intracranial Dural Arteriovenous Fistulae

Endovascular Treatment of a Dural Arteriovenous Fistula after Cerebral Sinovenous Thrombosis in a Child

“…While Cognard type I DAVF has a benign course allowing conservative treatment, reflux into the sinus of type II may induce intracranial hypertension and hemorrhaging requiring treatment [3]. Although endovascular therapy is the primary treatment for the pediatric population, the approach depends on the DAVF angioarchitecture in the angiogram [1, 11], since the small diameter of the vessels in younger children may preclude catheterization. Although indications for therapy include symptoms progression and cardiac enlargement, venous reflux at angiogram requires treatment to avoid intracranial hemorrhage [3].…”

Changing Clinical and Therapeutic Trends in Tentorial Dural Arteriovenous Fistulas: A Systematic Review

“…More recently, dual-lumen balloon microcatheters are used that allow the unopposed forward penetration of Onyx, without the time-consuming effort of plug formation, while concurrently decreasing the risk of premature proximal reflux. 15 The posterior branch of the middle meningeal artery almost always provides arterial supply to a TDAVF and provides a natural direct access to the venous collector system of the fistula. Furthermore, the middle meningeal artery and its branches run a relatively straight course and are anchored on the dura, making failed microcatheter retrieval rare despite substantial Onyx reflux.…”

Endovascular Treatment of Dural Arteriovenous Fistulas of the Anterior or Posterior Condylar Vein

“…Endovascular therapy of DAVFs has become the most widely used treatment modality as it is considered to be a safe and effective method [2,32]. It can be performed as transvenous embolization, transarterial embolization or as a combination thereof but both have the same aim of occluding the point of the fistula [2,32].…”
