“…BTAI is a clinically rare but fatal condition ( 17 ). RFs serve as a chief risk factor for BTAI ( 18 , 19 ). The retrospective study by Choi et al showed that RFs contributed to approximately 22.9% of all closed TAI cases ( 20 ).…”

Background: Delayed thoracic aortic injury (DTAI) induced by left closed rib fractures (RFs) is a clinically rare blunt injury to the thoracic aorta with an insidious onset. DTAI is very prone to missed diagnosis due to the unreliability of using the initial post-injury computed tomography (CT) scan to explicitly detect any signs of an aortic injury, potentially leading to a fatal hemorrhage. Timely diagnosis and treatment are therefore key to preventing such deadly complications. With that said, not all cases of left RFs lead to delayed aortic injuries, so how can surgeons tell which cases are to be culled and focused on? Also, what kinds of treatment should be administered upon detection? Methods: A retrospective analysis was performed on the clinical data of DTAI cases induced by left closed RF that were admitted to our Hospital from June 2015 through June 2020. Injuries to the aortic tunica adventitia or the elastic layer were intraoperatively confirmed. CT scan findings, locations and numbers of RFs, as well as the choices of surgical procedure were reviewed postoperatively. In addition, a literature review was conducted to analyze characteristics shared by similar cases.Results: This study included 7 patients treated by our hospital and 8 reported in the literature. The broken ends of RFs causing aortic wall injury (including the tunica adventitia) were all found in the medial to the lateral erector spinae. All patients in our hospital received internal fixation for RFs and thoracoscopic removal of free bone fragments (if any). Concomitant injuries were managed either by simultaneous or staged surgery.Conclusions: For multiple left RFs with the broken ends located in the inside of the lateral erector spinae, the number of fractured ribs ≥4 and a smaller number of fractured ribs with multiple fractures in a single rib are important factors for DTAI. Active surgical intervention is recommended for patients with these important factors. The specific intervention is tailored to each patient's particular needs to eliminate the risk of developing life-threatening thoracic aortic injury (TAI) and rupture.
