Arch replacement combined with antegrade stent grafting of the descending aorta represents a hybrid surgical approach for extensive thoracic aortic disease. This multicentre study evaluates the early results of this method in complex aortic dissection (AD). METHODS: Retrospective data acquisition was achieved by institution of an international registry. A hybrid stent graft with integrated vascular prosthesis for arch replacement (E-vita open®) was used. From January 2005 to March 2009, 106 patients (mean age 57; 77% male) with complex AD (55 acute, 51 chronic) were studied. RESULTS: As many as 49/106 (46%) patients underwent emergency surgery. Stent-graft deployment and arch replacement (95 total, 11 subtotal) were performed under hypothermic circulatory arrest (HCA (8±6min) and selective antegrade cerebral perfusion (SACP) (74±23min). Stent-graft placement into the true lumen was successful in all but one case (99%). Ascending aortic replacement was performed in 91/106 (86%), aortic valve repair/replacement in 49/106 (46%), coronary artery bypass grafting (CABG) in 17/106 (16%) and mitral valve repair in 2/106 (2%). Cardiopulmonary bypass (CPB) and cardiac arrest times were 242±64 and 144±44min, respectively. In-hospital mortality was 12% (13/106; six acute, seven chronic AD) and new strokes observed in 5/106 (5%). The false lumen (FL) was evaluated in 96/106 (91%) patients postoperatively. At first follow-up computed tomography (CT)-examination, thoracic FL thrombosis was 93% (76 complete, 13 partial) and 58% (31 complete, 25 partial) in the thoraco-abdominal aorta. CONCLUSIONS: By combining arch replacement with downstream stent grafting, one-stage repair of complex aortic dissection with almost unanimous thoracic FL thrombosis can be achieved at acceptable perioperative risk.

Abstract
Arch replacement combined with antegrade stent grafting of the descending aorta represents a hybrid surgical approach for extensive thoracic aortic disease. This multicentre study evaluates the early results of this method in complex aortic dissection (AD). METHODS: Retrospective data acquisition was achieved by institution of an international registry. A hybrid stent graft with integrated vascular prosthesis for arch replacement (E-vita open®) was used. From January 2005 to March 2009, 106 patients (mean age 57; 77% male) with complex AD (55 acute, 51 chronic) were studied. RESULTS: As many as 49/106 (46%) patients underwent emergency surgery. Stent-graft deployment and arch replacement (95 total, 11 subtotal) were performed under hypothermic circulatory arrest (HCA (8±6min) and selective antegrade cerebral perfusion (SACP) (74±23min). Stent-graft placement into the true lumen was successful in all but one case (99%). Ascending aortic replacement was performed in 91/106 (86%), aortic valve repair/replacement in 49/106 (46%), coronary artery bypass grafting (CABG) in 17/106 (16%) and mitral valve repair in 2/106 (2%). Cardiopulmonary bypass (CPB) and cardiac arrest times were 242±64 and 144±44min, respectively. In-hospital mortality was 12% (13/106; six acute, seven chronic AD) and new strokes observed in 5/106 (5%). The false lumen (FL) was evaluated in 96/106 (91%) patients postoperatively. At first follow-up computed tomography (CT)-examination, thoracic FL thrombosis was 93% (76 complete, 13 partial) and 58% (31 complete, 25 partial) in the thoraco-abdominal aorta.
