Abstract

Objective: We report a rare case of posterior condylar canal (PCC) dural arteriovenous fistula (dAVF) treated by transvenous embolization (TVE).

Case Presentations: A male in his 60s with pulsatile tinnitus visited our hospital. DSA revealed dAVF near thePCC. Feeders were bilateral ascending pharyngeal arteries and left occipital artery, and drainer was posterior condylar vein (PCV). We treated this case by TVE of the shunted pouch and PCV using coils and n-butylcyanoacrylate without complication.

Conclusion: Understanding of angioarchitecture using reconstruction of 3D-DSA was useful for the diagnosis and treatment of the rare PCC dAVF case.
