Abstract

Background: The aim of the present study was to define the possible anatomical and technical parameter that might predict the occurrence of gutter endoleak or type Ia endoleak (EL Ia) in patients treated with the chimney graft (CG) technique for the brachiocephalic trunk (BCT) and left common carotid artery (LCCA) due to aortic arch pathologies. Methods: We reviewed our institutional endovascular aortic database of patients, who between 2010 and 2018 had undergone thoracic endovascular aortic repair (TEVAR) with chimney graft technique (ChTEVAR) as a debranching method of the supraaortic arteries. Results: ChTEVAR was performed in 45 patients of whom a chimney in both the LCCA and the BCT was used in 32 patients, only in the LCCA in twelve patients, and only in the BCT in one patient. Eight patients (17.8%) had an EL Ia (based on postoperative computed tomography angiography). No late EL Ia was detected during the follow-up period. All patients with a post-operative EL Ia received 2 CGs with one each for the BCT, and LCCA had either no or a sealing ring distal to the most distal chimney of less than 10 mm versus patients with a longer sealing zone (P = 0.043). Patients with an endoleak did not differ from those without endoleak with respect to stent-graft oversizing, the diameter of the proximal and distal landing zones, or the aortic diameter directly proximal to the pathology. Conclusions: A sealing ring distal to the most distal chimney of more than 10 mm seems to be associated with a reduced risk of an EL Ia. The relatively few patients and the single-center nature require larger studies to verify the present results.
