Dural arteriovenous fistula (DAVF) after venous sinus stent (VSS) for presumed idiopathic intracranial hypertension (IIH): A case report and literature review

Dural arteriovenous fistulas (DAVFs) are rare but significant intracranial vascular malformations that are usually idiopathic and can lead to severe complications like venous hypertension and intracranial hemorrhage. We present 2 cases of DAVF occurring after venous sinus stenting (VSS) for presumed idiopathic intracranial hypertension (IIH) in a 51-year-old and a 52-year-old female. In both patients, Cognard type 1 DAVF was detected by Catheter angiography and successfully obliterated with Onyx™ embolization. These cases suggest that VSS may either unmask pre-existing DAVFs by altering intracranial pressure dynamics or induce new fistula formation by angiogenic factors or stent-induced hemodynamic changes. Clinicians should maintain an index of suspicion for DAVF in patients with persistent symptoms post-VSS and catheter angiography might be needed to detect the DAVFs.

Abstract

Dural arteriovenous fistulas (DAVFs) are rare but significant intracranial vascular malformations that are usually idiopathic and can lead to severe complications like venous hypertension and intracranial hemorrhage. We present 2 cases of DAVF occurring after venous sinus stenting (VSS) for presumed idiopathic intracranial hypertension (IIH) in a 51-year-old and a 52-year-old female. In both patients, Cognard type 1 DAVF was detected by Catheter angiography and successfully obliterated with Onyx™ embolization. These cases suggest that VSS may either unmask pre-existing DAVFs by altering intracranial pressure dynamics or induce new fistula formation by angiogenic factors or stent-induced hemodynamic changes. Clinicians should maintain an index of suspicion for DAVF in patients with persistent symptoms post-VSS and catheter angiography might be needed to detect the DAVFs.
