AIM: Reinterventions following previous ascending aorta and aortic arch repair are uncommon, but technically challenging and often burdened with high morbidity and mortality. The aim of this article is to present a single-center experience in the treatment of this complex pathology, using different surgical approaches.
METHODS: Between 1999 and 2014, 17 patients (14 males, mean age 73±16 years) underwent ascending aorta and aortic arch redo surgery at our Department. A prospectively maintained database including thoracic aortic procedures was reviewed retrospectively to collect data on redo patients.
RESULTS: In 13 cases the index procedure was an endovascular or hybrid procedure on the aortic arch performed at our Department, for an in-house reintervention rate of 6.9% (13/188). In 10 cases the cause of reintervention was stent-graft distal migration, treated by means of endovascular relining in all cases, associated with adjunctive supra-aortic trunks debranching via sternotomy in 6 cases. In 5 cases the cause of reintervention was retrograde ascending aortic dissection, in 1 case ascending aortic anastomotic pseudoaneurysm following supra-aortic trunk debranching, and in 1 case mediastinitis following implantation of an endovascular plug previously used to treat an ascending aortic pseudoaneurysm. In these last 7 cases, all patients were treated by means of ascending and arch surgical replacement under deep hypothermic circulatory arrest (DHCA) and antegrade cerebral perfusion (ACP). No 30-day mortality was observed. Major perioperative morbidity included 1 paraplegia, 1 minor stroke, 1 bleeding requiring reintervention, and 3 cases of respiratory failure requiring prolonged intubation (2) or tracheostomy (1).
CONCLUSION: In our experience, incidence of serious complications requiring reinterventions following ascending aorta or aortic arch repair is not negligible. Redo surgery in ascending aorta and aortic arch is feasible in high-volume and experienced centers, as it often requires hybrid repair via midline sternotomy, or surgical replacement under DHCA and ACP.
