Background
Blunt thoracic aortic injuries (BTAI) are life-threatening emergencies with almost 80%prehospital mortality rates. Traditionally, open repair was carried out, but this confers severe physiological stress and perioperative complications. The minimally invasive thoracic endovascular aortic repair (TEVAR) has shown to be superior. Our study aims to study primary outcomes of patients who underwent TEVAR for BTAI in two local hospitals.
Methods
This was a double-centre retrospective study that of patients who underwent TEVAR for traumatic BTAI in Khoo Teck Puat Hospital and Tan Tock Seng Hospital, Singapore, from 2013 to 2023. Information gathered included Injury Severity Score (ISS) and stent technical details. Primary outcomes included: 30-day mortality, 1-year mortality, ICU length of stay (LOS),hospital LOS, stent-related complications, re-intervention and death. Any evidence of follow-up was recorded.
Results
A total of 16 patients were included. 68.75% (n=11) were male, 50% (n=8) were Chinese and 68.75% (n=11) suffered their injuries following road traffic accidents. Mean age at incident was 45.6 and mean ISS was 18.9. All had single-stent deployment with majority in Zones 2 and 3. Half (n=8) had coverage of the subclavian artery. There were no ischemic symptoms related to coverage. Mean total months of follow-up was 15 (3 patients returned to their home countries after discharge). Average ICU LOS was 4.25 days, and hospital LOS was 26.75 days. 30-dayand 1-year survival was 93.8% (n=15) and 62.5% (n=10) respectively. 1 patient reported stent-related endoleak requiring re-intervention.
Conclusion
Although there remains to be further research delving into late complications and long-term impacts, this study suggests safety of and supports use of TEVAR in BTAI management.
