{Abstract}: BACKGROUND: Blunt thoracic aortic injury (BTAI) represents one of the most devastating scenarios of vascular trauma which warrants prompt recognition with expedited management. Clinical manifestations of BTAI may not be straightforward to detect and may be misdiagnosed. Therefore, diagnosis of BTAI requires a high index of suspicion based on the mechanism of injury along with urgent transfer to centers with appropriate expertise and facilities.
METHODS: We provide an expert-based narrative review on endovascular treatment of BTAI highlighting indications, techniques, results, and challenges.
RESULTS: Multiple imaging modalities can be used including computed tomography angiography, transesophageal echocardiography, magnetic resonance imaging, and intravascular ultrasound. Whilst conservative pharmacological management can be a safe option in low-grade BTAI, thoracic endovascular aortic repair has become the gold-standard strategy in most cases, replacing open surgical repair. Nevertheless, it is important to account for patient demographics particularly age, severity of injury, choice of endograft including its type and size, and endovascular technique including landing zone and left subclavian artery revascularization.
CONCLUSIONS: Overall, TEVAR in BTAI has been shown to be an efficacious strategy with favorable early outcomes. In contrast, less is known on the long-term clinical outcomes of TEVAR in BTAI. Hence, despite the optimal early technical and clinical success rates, concerns remain about the need for long-term surveillance. The exact timing of follow-up and the integration of different modalities that can also investigate potential downstream cardiovascular effects remain hot topics for future research. Finally, industry should focus on developing more compliant endografts to improve the stiffness mismatch between the endograft and the aorta to optimize results.
