Dural Arteriovenous Fistula Formation Complicated Cerebral Venous Sinus Stenosis After Venous Sinus Stenting.

Abstract

Venous stenting has become a promising treatment for venous sinus stenosis. However, it is not without its own set of risks. We reported de novo formation of dural arteriovenous fistula poststenting for venous sinus stenosis in a patient with pseudotumor cerebri. Multiple factors, including subclinical thrombus formation, sinus wall injury by stent placement, and up-regulated inflammatory factors, may contribute to its pathogenesis. This case indicates that physicians may need to be aware of this rare complication, which can be managed without resumption of pseudotumor cerebri symptoms.
