Traumatic Pseudoaneurysms Can Be Treated With the Willis Covered Stent

Background: Traumatic pseudoaneurysm of the internal carotid artery (ICA) has traditionally required complex surgical interventions. In recent studies, coil embolization and single or double bare-stent placement with or without coil embolization illustrated immediate and short-term success in the management of traumatic pseudoaneurysms with preservation of the ICA. Objective: To evaluate the clinical efficacy of the Willis covered stent for treatment of traumatic pseudoaneurysm of the ICA. Design/Methods: This is a prospective study of 38 patients with head and neck trauma, performed over 39 months. Thirteen patients were found to have traumatic pseudoaneurysms in 14 ICAs. Follow-up imaging was performed 1, 3, 6, and 12 months after the procedure and annually thereafter. Results: A delay in diagnosis occurred in all patients, and time from trauma to endovascular treatment varied from 1 month to 24 months. The Willis covered stent was placed in all 14 pseudoaneurysms.
