“…It accounts for 10-15% of intracranial vascular malformations commonly found in the transverse sinus-sigmoid sinus area, cavernous sinus area, tentorium of the cerebellum area, and superior sagittal sinus area (1,2). DAVF usually occurs in people aged 50-70 years and is slightly more common in men than in women (3). The pathophysiology of DAVF is an obstruction caused by inflammation, thrombosis, and stenosis, which leads to congestion and venous hypertension.…”

IntroductionTo evaluate treatment strategies and clinical outcomes following endovascular embolization of tentorial dural arteriovenous fistulas.MethodsWe retrospectively analyzed 19 patients with tentorial dural arteriovenous fistulas admitted to the Department of Neurosurgery at Jiangsu Provincial People’s Hospital between October 2015 and May 2022, all treated with endovascular therapy. To collect and analyze patients’ clinical presentation, imaging data, postoperative complications, and prognosis and to analyze the safety and clinical outcomes of endovascular treatment of tentorial dural arteriovenous fistulas.ResultsImaging cure was achieved in 18 patients, with the arterial route chosen for embolization in 17 patients and the venous route in one patient; one patient received partial embolization. Staged embolization was performed in four patients. At postoperative follow-up of 9–83 months (37.8 ± 21.2), all 19 patients had recovered well (mRS score ≤ 2). Three patients experienced perioperative complications: intraoperative Onyx reflux into the middle cerebral artery in one patient; postoperative permanent limited left visual field loss and deafness in the left ear in one patient; and transient diplopia, vertigo, and decreased pain and temperature sensation of the left limb in one patient, with no abnormalities on post-procedure magnetic resonance examinations. A total of 17 patients completed a postoperative digital subtraction angiography review during follow-up, and one patient had a recurrence of an arteriovenous fistula.ConclusionEndovascular treatment of tentorial dural arteriovenous fistulas is safe and effective. Reduction of the Borden or Cognard classification via eliminating cortical venous reflux through multi-staged embolization or combined open surgery is a reasonable goal of treatment where complete obliteration of the fistula is not achievable.

“…1 Dural arteriovenous fistulas (DAVFs) are abnormal shingles between the arterial and venous systems within the dural membrane, accounting for about 10% of intracranial vascular malformations, and about 20%–33% of DAVFs present as intracranial hemorrhage. 2 Although most DAVFs patients do not experience significant discomfort, some patients may experience significant complications, 3 namely manifestations of venous hypertension, including varicose veins, pain and swelling, pulsatile tinnitus, etc. In severe cases, intracranial hemorrhage or edema, seizures, and other symptoms may occur.…”
