PURPOSE: To examine the evolving roles of endovascular and open approaches in treatment of symptomatic innominate artery (IA) disease. METHODS: Patients treated for symptomatic IA lesions with or without involvement of the right common carotid and/or right subclavian arteries between 1997 and 2006 were identified. Charts and diagnostic studies were retrospectively reviewed. RESULTS: Of 18 patients treated, 8 required open reconstruction. Ten patients with high-grade focal stenosis were stented. Immediate technical and clinical success was 100% among all patients. Mean follow-up time was 25 and 27 months for endovascular and open interventions, respectively. The primary patency rates were 78% +/- 14 and 80% +/- 10 for endovascular and open groups, respectively. Assisted primary patency rate was 100% for both groups. There were no peri-operative mortalities or neurological events. We encountered two systemic (pulmonary) complications and one access-related complication among open and endovascular patients, respectively. CONCLUSION: Endovascular repair is evolving as a primary mode of therapy for focal IA lesions while open approach is reserved for more extensive disease. Patho-anatomical characteristics of a given IA lesion along with peri-operative risk assessment determine a proper surgical approach.
