Cerebrospinal Fluid-Venous Fistulas.

ABSTRACT

Cerebrospinal fluid-venous fistulas (CSFVFs) were first described in 2014 and have since become an increasingly diagnosed cause of spontaneous intracranial hypotension due to increased clinical recognition and advancements in diagnostic modalities. In this review, the authors discuss CSFVF epidemiology, the variety of clinical presentations, the authors' preferred diagnostic approach, recent advancements in diagnostic methods, treatment options, current challenges, and directions of future research.
