Transvenous embolization of a high-flow, posttraumatic fistula between the posterior communicating artery and retroclival venous plexus.
Traumatic injuries of the posterior communicating artery are distinctly rare. We report an unusual case of traumatic tear of the posterior communicating artery with fistulous communication to the adjacent, retroclival venous plexus. The fistula, and an accompanying large venous aneurysm, was completely occluded via transvenous embolization. The patency of the posterior communicating artery was preserved.
