Abstract
Caroticocavernous fistulas (CCFs) occur due to an abnormal communication between the
high-pressure carotid artery system and the relatively lower pressure cavernous sinus
system. They present with dramatic clinical presentations comprising among other things
a swollen red eye with associated loss of vision to a varying degree. Blunt trauma
sustained to the head, especially by two-wheeler riders, is the most common cause
of the direct CCF and hence a practicing interventional radiologist in a developing
country is very likely to encounter this entity in clinical practice. The authors
intend to present a pictorial essay of the clinical presentations, imaging findings,
endovascular management, and clinical follow-up for CCFs.
