1655 Thoracic Aortic Aneurysmal Disease: Timing and Outcome of Surgery

Abstract

Abstract Aim A thoracic aortic aneurysm (TAA) is a pathological dilatation of the thoracic aorta. There is significant morbidity associated with a dilated aorta including mortality. Open thoracic surgery is the mainstay of management for proximal lesions, offering definitive treatment. We aim to evaluate the outcomes of patients operated on for TAA and consider high risk associations for mortality. Method Data was retrospectively collected from 234 patients that underwent elective open thoracic surgery at UHS for TAA disease, between 2015 and 2019. Demographics, clinical factors, surgical details, as well as outcome measures were gathered. Results There were 166 males (71%) and 68 females (29%), with a mean age of 66 years. We found that 105 operations involved the aortic root, 171 the ascending aorta, 20 the aortic arch and 12 the descending aorta. 30 day mortality was 5.13%. Female patients that underwent aortic root surgery (P = 0.05), as well as those with prosthetic aortic valves (P = 0.01)and post-operative complications were associated with a significantly higher mortality. Conclusions A number of factors are associated with morbidity and mortality in this high-risk Surgery. These should be considered when discussing risks of intervention with patients.
