This paper reports that decompression of the facial nerve by transarterial Onyx embolization may relieve hemifacial spasm (HFS) caused by dilated veins due to a right petrosal dural arteriovenous fistula (DAVF). A 56-year-old man suffered severe chronic right HFS associated with a dilated right petrosal vein lying in the vicinity of the facial nerve. The right petrosal DAVF was reached through the middle meningeal artery using a transfemoral arterial approach and was occluded with Onyx 18 (M.T.I.- ev3, Irvine, CA, USA). There was complete remission of HFS without recurrence after two months of follow-up. This case supports vascular compression in the pathogenesis of HFS and suggests that facial nerve injury caused by a DAVF could be treated with transarterial Onyx embolization.

Introduction And Importance: A carotid-cavernous sinus fistula is an abnormal connection between the internal or external carotid artery and the venous system of the cavernous sinus. It represents a rare entity, and it is often misdiagnosed due to its overlapping symptoms with other conditions such as cavernous sinus thrombosis or orbital inflammation. Cerebral angiography continues to be the gold standard for diagnosis and surgical planning in patients with CCF, and the endovascular trans-venous approach still represents the primary line of treatment.

Background: Intracranial dural arteriovenous fistula (dAVF) is a rare arteriovenous malformation with potentially severe complications. This study investigates the efficacy and safety of transarterial embolization (TAE) in treating petrous dAVFs through a retrospective analysis and literature review.

Case Description: A retrospective analysis of six patients with petrous dAVFs treated with TAE was conducted, accompanied by a systematic literature review to evaluate treatment outcomes.

Background: Dural arteriovenous fistula (DAVF) in the anterior cranial fossa (ACF) is known to show a high risk of intracranial hemorrhage. Recently, multi-modal fusion imaging with computed tomography angiography, computed tomography venography, and three-dimensional (3D) rotation angiography have been used preoperatively to ensure anatomical safety. We report on endovascular treatment as a first-line approach for ACFDAVF based on the understanding of vascular anatomy obtained from multi-modal fusion imaging.

Congenital external carotid-jugular fistula is a rare condition caused by altered embryologic development of the vasculature. It is usually treated with surgery or endovascular embolization; controversy exists on the best therapeutic approach and the specific endovascular technique. We report a case of a complex congenital fistula between the external carotid and jugular veins treated with a combined trans-arterial dual microcatheter coiling technique followed by n-BCA (n-butyl cyanoacrylate) glue embolization.

Article Synopsis
  • Dural arteriovenous fistula (dAVF) is typically treated with endovascular therapy, but this method has risks like embolic material migration and brain infarction.* -
  • A case involving a man with left hemiparesis revealed a successfully treated dAVF, but also resulted in complications such as subarachnoid hemorrhage post-treatment.* -
  • The case emphasizes the importance of careful preoperative assessments and thorough postoperative monitoring in managing dAVF, with a need for more research on unexplained complications.*
