Venous anatomy and endovascular treatment of hypoglossal canal dural arteriovenous fistula
Hypoglossal canal dural arteriovenous fistula(DAVF)is a subtype of DAVF involving the anterior condylar vein and/or anterior condylar confluence.Due to its low incidence and the complex venous anatomy around the hypoglossal canal,hypoglossal canal DAVF is often underrecognized by clinicians.Endovascular treatment has become the first-line choice for hypoglossal canal DAVF.In this paper,the authors summarized the anatomy surrounding the hypoglossal canal,various endovascular treatment strategies and approaches,and related complications,with the aim of offering clinical insights into hypoglossal canal DAVF treatment.
