BACKGROUND AND PURPOSE: Endovascular treatment of vascular lesions has revolutionized the treatment of arterial pseudoaneurysms. We describe our experience in treating carotid or vertebral pseudoaneurysms with covered stents. MATERIALS AND METHODS: Ten patients with carotid or vertebral pseudoaneurysms treated with self-expanding or balloon-expandable covered stents were retrospectively reviewed after we obtained institutional review board approval. Distal protection devices were not used. All patients except 1 received anticoagulation therapy. Antiplatelet therapy was used in 8 of 10 patients. Follow-up was performed from 5 days to 25 months. Patients were followed with digital subtraction angiography, CT angiography (CTA), and/or sonography (US). RESULTS: Pseudoaneurysm occlusion was obtained in all 10 patients. None of the pseudoaneurysms recanalized during the follow-up period. One patient had a distal embolization to the middle cerebral artery despite anticoagulation and antiplatelet therapy. One patient who did not receive any anticoagulation had stent occlusion at 4.5 months. Anticoagulation was stopped after 6 months in 2 patients with persistent stent patency and no neurologic complications for >1 year. Both US and CTA were useful for extracranial stent surveillance. CTA was helpful for intracranial stent surveillance. CONCLUSION: In this small series, the use of covered stents allowed safe and effective treatment of pseudoaneurysms occurring in the cervical and cephalic segments of the carotid and vertebral arteries.
