Is total debranching a safe procedure for extensive aortic-arch disease? A single experience of 27 cases

OBJECTIVE: Thoracic, arch, and proximal descending thoracic aorta diseases are still considered an enormous challenge. The hybrid approach developed in recent years (supra-aortic trunks debranching and thoracic endovascular repair aortic repair; TEVAR) may improve the morbidity and mortality of the population at risk. The aim of this study was to analyze retrospectively our experience in the hybrid treatment of aortic-arch aneurysms and dissections. METHOD: We carried out a retrospective review of 27 patients who required a surgical debranching of the supra-aortic trunks and a TEVAR in the management of the aortic arch and proximal descending thoracic aortic disease. The aortic lesions included 18 degenerative arch-aortic aneurysms, four complicated aortic dissections, two subclavian artery aneurysms, and three penetrating atherosclerotic ulcers. Technical success was achieved in all patients. RESULTS: The 30-day mortality rate was 11.1% (3/27). Mean follow-up was 16.7 months (range, 1–56), and the survival rate was 77.8%. The endoleaks’ rate was 3.7% (1/27), due to a stent-graft migration. CONCLUSION: Hybrid approaches may represent an alternative option in the treatment of complex aortic lesions involving the arch and the proximal descending thoracic aorta in high-risk patients and emergency cases. However, the promising early results need to be confirmed by longer follow-up and larger comparative series.
