    BackgroundPersistent primitive trigeminal artery (PPTA) is the most common type of fetal carotid-basilar persisting communication in adulthood; however, carotid-cavernous fistulas (CCFs) associated with PPTA are rare.Case DescriptionAn 84-year-old woman presented with traumatic CCF associated with PPTA manifesting as vascular bruit. Transarterial embolization was performed. Although a detachable coil was deployed at the fistula point, it was easy to migrate into the cavernous sinus because of the high-flow shunt. Therefore, a stent was deployed in the PPTA, and the inner lumen of the stent with a focus on the fistula point was occluded by using coils. Subsequently, the CCF completely disappeared.ConclusionsIn-stent coil embolization was effective and reasonable for the high-flow CCF associated with the PPTA. This method reduced the number of coils required and operating time. However, careful preservation of perforators is needed.Copyright © 2019 Elsevier Inc. All rights reserved.
