How should I treat a symptomatic post dissection carotid aneurysm?

BACKGROUND: A 28-year-old woman was admitted for an acute ischaemic stroke. She had a past history of traumatic dissection of the right carotid artery. Because the ischaemic stroke was considered a failure of antithrombotic therapy, we decided to treat the dissecting aneurysm. INVESTIGATION: CT angiography and conventional angiography revealed a subpetrous extracranial right carotid aneurysm. DIAGNOSIS: Symptomatic carotid post-dissection aneurysm. MANAGEMENT: Endovascular therapy. We realised a telescopic implantation of three auto-expandable stents (Carotid WALLSTENT®; Boston Scientific, Natick, MA, USA) to exclude the aneurysm.
