    Internal carotid artery fenestration (ICAF) is a rare congenital anomaly, with its coexistence with contralateral ICA dissection being exceptionally uncommon.

  • 2

    A 71-year-old female presented with episodic dizziness, and imaging confirmed bilateral ICA dissections and a right ICA fenestration.

  • 3

    Computational fluid dynamics (CFD) analysis indicated that the left ICA dissection was high-risk for rupture, while the right fenestration was hemodynamically stable.

  • 4

    The patient underwent stent-assisted coiling for the left dissection after receiving dual antiplatelet therapy, resulting in complete resolution of symptoms.

  • 5

    Follow-up imaging confirmed the left dissection's resolution and stable morphology of the right fenestration, highlighting the role of CFD in treatment guidance.
