OBJECTIVES: Open repair of aortic arch aneurysms can be technically challenging. Hybrid approaches have been developed to facilitate arch repairs and improve their clinical outcomes in high-risk patients. We examined treatment options and early outcomes in patients whose thoracic endografts were deployed to include Zone 0. METHODS: Between 2005 and 2011, a hybrid approach in which the endograft was deployed in the ascending aorta was used in 29 patients (median age 67 years, range 32-85 years). The indication for surgery was saccular arch aneurysm in 11 patients (37.9%), fusiform arch aneurysm with or without involvement of the proximal descending aorta in 10 (34.5%), proximal Type I endoleak after endovascular repair of the descending aorta in 5 (17.2%), chronic Type III (Type B) aortic dissection with aneurysmal arch formation in 2 (6.9%) and acute Type I (Type A) dissection with prior repair of an extent I thoracoabdominal aneurysm in 1 (3.4%). Six patients (20.7%) had previously undergone a sternotomy. One-, two- or three-branch aortobrachiocephalic de-branching, with or without concomitant heart surgery, was performed in 28 patients and extra-anatomic bypass in 1. RESULTS: Two patients (6.9%) died during postoperative hospitalization. Overall survival during the follow-up period (median 411 days) was 79.3%. Five neurological events occurred: one extensive stroke, two minor strokes (10.3%) and two episodes of paraparesis (6.9%), one with partial recovery and one with full recovery. CONCLUSIONS: The hybrid approach enables the treatment of aortic arch disease in high-risk individuals. Long-term follow-up data are needed.
