Evolving strategies in treatment of isolated symptomatic innominate artery disease.
OBJECTIVE
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.


CONCLUSIONS
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.
