Objective: Ingenuity is required in treating carotid artery stenosis associated with persistent primitive hypoglossal artery (PPHA) because of anatomical singularity.

Case Presentation: A 69-year-old male presented with right thalamic infarction and was found to have marked stenosis of the right internal carotid artery (ICA). PPHA extending from a site distal to the stenosed area of the right ICA to the right vertebral artery was observed. Since there were few collateral channels for the posterior circulation, one FilterWire EZ (Boston Scientific, Natick, MA, USA) each was placed in the ICA and PPHA, and carotid artery stenting was performed.

Conclusion: The effectiveness of the double distal filter protection technique for ICA stenosis associated with PPHA and tips for the retrieval of the filter devices are reported.
