Case 2: a 63-year-old male with 80% stenosis in the left carotid bulb as well as an ipsilateral posterior communicating artery measuring 2 mm. (A,C). Carotid angioplasty and stenting were performed successfully (B). At that time the aneurysm was considered too small to require treatment. A follow-up angiographic performed 6 months after carotid repair showed haemodynamic changes in intracranial circulation with opacification of the anterior cerebral artery (E, arrow) and posterior cerebral artery where as in the previous angiogram there was inversion of flow in the posterior communicating artery (E, star), facts that resulted in changes in the configuration of the aneurysm morphology (E).
