Objective: This study analyzed total aortic arch reconstruction in a contemporary comparison of current open and endovascular repair.Methods: Endovascular (group 1) and open arch procedures (group 2) performed during 2007 to 2013 were entered in a prospective database and retrospectively analyzed. Endovascular repair (proximal landing zones 0-1), with or without a hybrid adjunct, was selected for patients with a high comorbidity profile and fit anatomy. Operations involving coverage of left subclavian artery only (zone 2 proximal landing: n = 41) and open hemiarch replacement (n = 434) were excluded. Early and midterm mortality and major complications were assessed.Results: Overall, 100 (78 men; mean age, 68 years) consecutive procedures were analyzed: 29 patients in group 2 and 71 in group 1. Seven group 1 patients were treated with branched or chimney stent graft, and 64 with partial or total debranching and straight stent graft. The 29 patients in group 2 were younger (mean age, 61.9 vs 70.3; P = .005), more frequently females (48.2% vs 11.3; P < .001) with less cardiac (6.9% vs 38.2%; P = .001), hypertensive (58.5% vs 88.4%; P =. 002), and peripheral artery (0% vs 16.2%; P = .031) disease. At 30 days, there were six deaths in group 1 and four in group 2 (8.5% vs 13.8%; odds ratio, 1.7; 95% confidence interval, 0.45-6.66; P = .47), and four strokes in group 1 and one in group 2 (odds ratio, 0.59; 95% confidence interval, 0.06-5.59; P = 1). Spinal cord ischemia occurred in two group 1 patients and in no group 2 patients. Three retrograde dissections (1 fatal) were detected in group 1. During a mean follow-up of 26.2 months, two type I endoleaks and three reinterventions were recorded in group 1 (all for persistent endoleak), and one reintervention was performed in group 2. According to Kaplan Meier estimates, survival at 4 years was 79.8% in group 1 and 69.8% in group 2 (P = .62), and freedom from late reintervention was 94.6% and 95.5%, respectively (P = .82).Conclusions: Despite the older age and a higher comorbidity profile in patients with challenging aortic arch disease suitable and selected for endovascular arch repair, no significant differences were detected in perioperative and 4-year outcomes compared with the younger patients undergoing open arch total repair. An endovascular approach might also be a valid alternative to open surgery in average-risk patients with aortic arch diseases requiring 0 to 1 landing zones, when morphologically feasible. However, larger concurrent comparison and longer follow-up are needed to confirm this hypothesis.

Abstract

Objective: This study analyzed total aortic arch reconstruction in a contemporary comparison of current open and endovascular repair.Methods: Endovascular (group 1) and open arch procedures (group 2) performed during 2007 to 2013 were entered in a prospective database and retrospectively analyzed. Endovascular repair (proximal landing zones 0-1), with or without a hybrid adjunct, was selected for patients with a high comorbidity profile and fit anatomy. Operations involving coverage of left subclavian artery only (zone 2 proximal landing: n = 41) and open hemiarch replacement (n = 434) were excluded. Early and midterm mortality and major complications were assessed.Results: Overall, 100 (78 men; mean age, 68 years) consecutive procedures were analyzed: 29 patients in group 2 and 71 in group 1. Seven group 1 patients were treated with branched or chimney stent graft, and 64 with partial or total debranching and straight stent graft. The 29 patients in group 2 were younger (mean age, 61.9 vs 70.3; P = .005), more frequently females (48.2% vs 11.3; P < .001) with less cardiac (6.9% vs 38.2%; P = .001), hypertensive (58.5% vs 88.4%; P =. 002), and peripheral artery (0% vs 16.2%; P = .031) disease. At 30 days, there were six deaths in group 1 and four in group 2 (8.5% vs 13.8%; odds ratio, 1.7; 95% confidence interval, 0.45-6.66; P = .47), and four strokes in group 1 and one in group 2 (odds ratio, 0.59; 95% confidence interval, 0.06-5.59; P = 1). Spinal cord ischemia occurred in two group 1 patients and in no group 2 patients. Three retrograde dissections (1 fatal) were detected in group 1. During a mean follow-up of 26.2 months, two type I endoleaks and three reinterventions were recorded in group 1 (all for persistent endoleak), and one reintervention was performed in group 2.

An endovascular approach might also be a valid alternative to open surgery in average-risk patients with aortic arch diseases requiring 0 to 1 landing zones, when morphologically feasible.
