Purpose: Blunt thoracic aortic injury (BTAI) has a high mortality rate, and the occurrence of clinical complications is high. Several studies have reported the efficacy of thoracic endovascular aortic repair (TEVAR) for BTAI. This study aimed to clarify the use of TEVAR for BTAI., Methods: We analyzed 10 cases of TEVAR for BTAI from July 2011 to December 2020 at our hospital. Five of 10 cases of BTAI were caused by road traffic accidents, while five were caused by falls from a height., Results: The mean patient age was 59.3 years. When arriving at our hospital, seven of 10 patients were in shock. Nine of 10 cases of BTAI were at the aortic isthmus. With respect to BTAI severity, five of 10 patients were categorized as grade IV. Ps of non-survivors were extremely low. All patients underwent TEVAR. The mean surgical duration and volume of intraoperative blood loss were 77.5 minutes and 234 ml, respectively., Conclusion: The results of TEVAR for BTAI at our institution support previous reports, which show excellent clinical results. To further improve the outcomes, we must clarify the adaptation of nonoperative management (delayed repair), the optimal timing of invasive treatment, and the importance of long-term follow-up.

A 67-year-old man suffered a traffic accident and was transferred to an emergency hospital close to the scene. He was diagnosed to have bilateral pneumohemothorax with a lung contusion, an anterior fracture dislocation of the C6-vertebra and a cervical cord injury at the level of C7. On the 48th day, massive hemoptysis was suddenly recognized. He was transferred in a state of shock to our hospital to undergo hemostasis for the bleeding. On the day of admission, a selective arteriogram showed extravasation from the left bronchial artery, for which embolization was carried out using Gelfoam. In spite of this treatment, his hemoptysis continued. On the next day, a selective left internal mammary arteriogram showed an arteriovenous fistula between the left internal mammary artery and the left pulmonary vein without any apparent extravasation. The arteriovenous fistula was successfully embolized using platinum fiber coils. The patient no longer demonstrated any hemoptysis after embolization.
