Endovascular Management of Falcine Dural Arteriovenous Fistula-A Case Report and Review of Literature.

Abstract

Cranial dural arteriovenous (AV) fistulas are abnormal connections between the branches of dural arteries to dural veins or venous sinuses. They are most frequently located at the transverse sinus and cavernous sinus. They can occur at every cranial dural sinus. Dural AV fistula of falx cerebri is rare. A 62-year-old female presented with signs and symptoms of raised intracranial pressure. Radiological imaging revealed a dural AV fistula at the posterior one-third falx cerebri. She underwent transarterial embolization, and complete obliteration of the fistula was achieved. A detailed digital subtraction angiography study is warranted in patients with seemingly benign complaints like recurrent headaches, and falcine dural AV fistula should be identified and treated in the nick of time. We describe a very rare falcine dural AV fistula case and its management.
