Factors affecting success in endovascular treatment of acute aortic transections

Abstract

Aim: In this study, it was aimed to present the results of patients treated with endovascular treatment between 2002 and 2018 with the diagnosis of Acute Aortic Transection and the factors that may affect the success. Materials and Methods: A total of 17 patients were included in the study and it was planned as retrospectively. All data of the patients were collected by file searching method and demographic features of the patients were recorded. Written informed consent was obtained from all patients prior to study. Trauma types and gender ratios of the patients were calculated as percentages.. Contrast-enhanced thoraco-abdominal computed tomography was performed for definitive diagnosis, and endovascular treatment was evaluated. All patients deemed suitable for endovascular treatment were intervened within the first 24 hours. Results: The most majority of our patient group was in stage 4 and the most common etiology was recorded as in - vehicle traffic accidents. Of the 17 patients included in the study, 2 died in the early period and 1 died in the follow-up period. Complications such as graft migration, pseudo aneurysm and graft kinking, which are known as complications of endovascular treatment, were not encountered. Although the left subclavian artery was closed in 12 of 17 patients, only two of them required carotid-subclavian bypass. Conclusion: The fact that endovascular treatment can be applied with low mortality compared to conventional surgery reduces mortality in acute aortic transections. The most important factors affecting the success of the treatment are that the intervention is performed in the 24 hours, in experienced centers, and that 10% of the aortic diameter is not exceeded in the graft selection, and balloon dilatation is avoided.
