Blunt thoracic aortic injury (BTAI) is an uncommon yet serious diagnosis in trauma patients, with high on-scene mortality. BTAI typically occurs from rapid deceleration such as in motor vehicle collisions or high-altitude falls shearing the aorta just proximal to the ligamentum arteriosum. We report a case of a man in his 50s falling from a height of 15 m who presented hypotensive with retrosternal chest pain. Mobile chest X-ray showed a widened mediastinum with left-sided haemothorax. CT revealed a contained free aortic rupture just inferior to the origin of the left subclavian artery with bleeding into the mediastinum and left pleural space. The patient underwent urgent thoracic endovascular aortic repair (TEVAR) but arrested on-table due to a left-sided tension haemothorax requiring chest-drain decompression and haemostatic resuscitation. After return of spontaneous circulation, TEVAR was successfully performed. BTAI is a dynamic process; hence, timely imaging and minimally invasive surgical treatment are key to patients surviving grade III and IV aortic injuries.
钝性胸主动脉损伤(BTAI)是创伤患者中一种不常见但严重的诊断,现场死亡率很高。BTAI 通常由快速减速引起,如机动车碰撞或高空坠落,导致主动脉在动脉韧带近端被剪断。我们报告了一例 50 多岁男性从 15 米高处坠落,出现低血压和胸骨后胸痛。移动胸部 X 光片显示纵隔增宽,左侧血胸。CT 显示在左锁骨下动脉起源下方有一处局限的游离主动脉破裂,出血进入纵隔和左侧胸腔。患者接受了紧急胸主动脉腔内修复术(TEVAR),但由于左侧张力性血胸导致心跳骤停,需要进行胸腔引流减压和止血复苏。自主循环恢复后,成功进行了 TEVAR。BTAI 是一个动态过程;因此,及时的影像学和微创外科治疗是 III 级和 IV 级主动脉损伤患者存活的关键。
