AIM: The aim of this study was to report our experience with total and subtotal endovascular stent-grafting combined with aortic arch branch surgical revascularization for thoracic aortic arch aneurysms in high-risk patients. METHODS: From December 2000 to June 2005, among 38 patients treated with thoracic stent-grafts in our department, 10 patients (9 men; mean age 71+/-6 years) at high risk for open repair were candidates for endovascular repair and/or aortic arch branch extra-anatomical reconstruction due to inadequate proximal landing zones. The left subclavian artery was over-stented 6 cases for zone 2 aneurysms, and partial or total arch stent-grafting with simultaneous revascularization of the arch branches was performed in 4 cases for zones 0-1 aneurysms. RESULTS: Primary technical success rate was 100%. In-hospital mortality rate was 10%. Neither paraplegia, nor acute renal failure were recorded. Immediate or late surgical conversion was never required. One type 1b was successfully treated with additional stent-graft and 2 type-2 endoleaks were sealed by coil embolization. Mean follow-up was 21-months (range 3-48 months); overall, survival rate at 12, 26, and 36 months was 90%, 60%, and 30%, respectively. CONCLUSIONS: Endovascular repair for thoracic aortic arch aneurysms is feasible. However, our experience suggests stent-grafting is not free of risk, and long-term and larger follow-up is required.

Abstract

AIM: The aim of this study was to report our experience with total and subtotal endovascular stent-grafting combined with aortic arch branch surgical revascularization for thoracic aortic arch aneurysms in high-risk patients. METHODS: From December 2000 to June 2005, among 38 patients treated with thoracic stent-grafts in our department, 10 patients (9 men; mean age 71+/-6 years) at high risk for open repair were candidates for endovascular repair and/or aortic arch branch extra-anatomical reconstruction due to inadequate proximal landing zones. The left subclavian artery was over-stented 6 cases for zone 2 aneurysms, and partial or total arch stent-grafting with simultaneous revascularization of the arch branches was performed in 4 cases for zones 0-1 aneurysms. RESULTS: Primary technical success rate was 100%. In-hospital mortality rate was 10%. Neither paraplegia, nor acute renal failure were recorded. Immediate or late surgical conversion was never required. One type 1b was successfully treated with additional stent-graft and 2 type-2 endoleaks were sealed by coil embolization. Mean follow-up was 21-months (range 3-48 months); overall, survival rate at 12, 26, and 36 months was 90%, 60%, and 30%, respectively. CONCLUSIONS: Endovascular repair for thoracic aortic arch aneurysms is feasible. However, our experience suggests stent-grafting is not free of risk, and long-term and larger follow-up is required.
