The following article was reviewed: ¿single-center mid-term experience with chimney-graft technique for the preservation of flow to the supra-aortic branches¿ (robert shahverdyan et.Al, vascular, 2018, vol.26 (2), 175¿182, published online on october 12, 2017).The objective of the study was to investigate the feasibility and the mid-term outcomes of the chimney-graft technique for the revascularization of supra-aortic branches in patients with thoracic aortic pathologies involving the aortic arch.A retrospective analysis was done of a prospectively maintained database including all patients with aortic pathologies treated at the institution with chimney/snorkel technique of supra-aortic branches between january 2010 and july 2016.All patients were considered as high-risk candidates for open surgical procedures due to severe cardiac dysfunction, respiratory disorders, previous sternotomy or other medical conditions, and not suitable for arch-hybrid procedure according to the cardiothoracic surgeons within an interdisciplinary conference.A total of 49 supra-aortic branches were revascularised.In particular, a chimney-graft was implanted in the brachiocephalic trunk in 23 patients, in the left common carotid artery in 25 patients and in the left subclavian artery in a single patient.Double-barrel technique was performed in 11 patients, whereas a triple-barrel technique was performed in 19 patients.The conformable gore® tag® thoracic endoprosthesis was used in all but one patient (97%).The article states that one patient had a right common carotid artery - left common carotid artery (lcca) bypass due to an intraoperative dislocation and kinking of a gore® viabahn® endoprosthesis in the lcca.
