Endovascular Repair in Blunt Thoracic Aortic Injury: A 10-Year Single Center Experience

Background: Life -threatening blunt thoracic aortic injury (BTAI) typically occurs alongside multiple other traumatic injuries. Symptoms of BTAI can range from being asymptomatic in the case of intimal tears to becoming catastrophic in the case of uncontained aortic ruptures. The aim of this research was to examine the clinical outcomes for those who underwent thoracic endovascular aortic repair (TEVAR) in hospital settings. Methods: A cross-sectional retrospective study was conducted using patient data that were extracted from Al-Noor Specialist Hospital, Makkah, Saudi Arabia, for the duration between January 2011 and December 2021. This study included data from all patients aged 18 and up who had been diagnosed with BTAI and had undergone TEVAR. The BTAI diagnoses were confirmed using CT scans. Logistic regression was utilized to identify predictors of patients' health status improvement and length of stay. Results: A total of 80 patients were involved. Around 50.0% (n=40) of the patients had grade 3 thoracic aortic injuries. The median duration of stay was 14.00 days (Interquartile range 21.00). Only one patient developed post -procedure complications (1.3%). Almost one-third (31.3%; n=25) of the patients required subclavian coverage. One patient developed intraoperative endoleak (1.3%). One patient developed an access site complication (1.3%). The mortality rate within 30 days of the operation was 1.3%. The vast majority of the patients (92.5%; n=74) showed improvement upon discharge from the hospital. The baseline patient characteristics and length of hospitalization had no effect on the improvement of patient status upon discharge or their length of stay (p>0.05). Conclusion: Patients with BTAI have shown an excellent success rate with TEVAR and a low complication rate. Predictors of procedure success and length of stay need to be identified; however, this can't be done without larger -scale investigations. This can aid in the development of preventative measures that improve clinical outcomes for the patients.
