Objective. The study was aimed at assessing the in-hospital results of aortic arch endoprosthetic repair using different variants of endovascular supraaortic debranching.

Materials and methods. The analysis included 27 patients subjected within the framework of aortic arch endoprosthetic repair to various types of supraaortic endobranching, including the technique of parallel prostheses and implantation of fenestrated stent grafts. We analysed the clinical and morphological status of patients prior to operation, peculiarities of the intervention (type of debranching and Ishimaru’s classification zones in which the reconstruction was performed) and in-hospital results of treatment.

Results. The patients’ mean age amounted to 66 years. The main nosology (70%) was an aortic aneurysm. Nearly in 30% of cases, the operation was performed emergently for acute aortic syndrome. The main causes of refusal from the traditional prosthetic repair included chronic kidney disease (22.5%), chronic obstructive pulmonary disease (11%), acute cerebral ischaemia within the previous 6 months (15%). The technical success rate of the operation was achieved in 100% of cases. The average duration of the intervention amounted to 226 min, with the mean blood loss equalling 355 ml. The majority of reconstructions were performed in zones 1 and 2 according to Ishimaru (59 and 33%, respectively), in 2 (7%) patients prosthetic repair was performed in zone 0. The total number of the aortic branches involved into reconstruction amounted to 45. Intervention-related complications included 3 (11%) cases of acute cerebral circulation impairment, 2 (7.4%) aortic branch occlusions, and 1 (3.7%) type II endoleak. The in-hospital and 30-day mortality rates amounted to 3.7 and 7.4%, respectively.

Conclusions. Aortic arch endoprosthetic repair using supraaortic endobranching is considered to be an effective alternative method of treatment for patients with various pathology of the aortic arch and contraindications to traditional prosthetic repair involving artificial blood circulation.
