Endovascular management of a ruptured mycotic aneurysm of the innominate artery.

Abstract

Mycotic aneurysms of the innominate artery are infrequent lesions and, as such, represent challenging surgical problems. We describe herein a case of a ruptured mycotic innominate artery aneurysm, which developed after radical neck dissection and radiation therapy for tonsillar carcinoma. The aneurysm was successfully excluded from the systemic circulation with endoluminal placement of a covered stent, with efficacy confirmed by vascular imaging at 6 months follow-up. The patient suffered no permanent neurologic sequelae. Long-term follow-up and chronic antibiotic therapy will be necessary to avoid infection of the covered stent in this high-risk surgical patient.
