Background: Thoracic endovascular aortic repair (TEVAR) is a widely used procedure that has drastically changed the management of thoracic aortic diseases. We assess the effectiveness of supra-aortic debranching during antegrade TEVAR procedures with a retrospective analysis of our clinical experience.
Methods: Between December 2005 and April 2017, 55 patients underwent 64 TEVAR procedures. Among them, there were 8 male patients, mean age 72, who underwent hybrid antegrade stent-graft deployment. Particularly, for degenerative aneurysms of the aortic arch, 3 patients for aneurysm of descending thoracic aorta 3, for post-traumatic pseudoaneurysm 1, and for penetrating aortic ulcer 1 which had resulted in an aortoesophageal fistula. Proximal landing zones were Z0:1, Z1:3 and Z2:4. Type I hybrid aortic arch repair was performed in 1 case, carotid-carotid bypass in 2, carotid-subclavian in 5 and aorto-carotid in 1.
Results: The 30-day postoperative mortality was 12.5%. One patient suffered a temporary right hemiplegia which resolved after left aorto-carotid bypass. No endoleaks were observed postoperatively and in follow-up period. In the long term and a mean follow-up of 4.9 years, there were no deaths related to the stent-graft implantation or to revascularization procedures. Regarding the aortic arch rerouting procedure, there were no pseudoaneurysm or other anastomotic events.
Conclusions: Antegrade delivery of the endograft, combined with hybrid and revascularization procedures of the supra-aortic vessels is a safe treatment modality, in complex hostile anatomies. However, further improvements are recommended due to the presence of neurologic complications and reinterventions.
