Radiographic evaluation of ascending aortic injuries is rare because they are almost always immediately fatal. We report three cases of ascending aortic laceration studied by angiography, with a review of the literature and discussion of mechanisms of injury. The type of deceleration trauma resulting in ascending aortic laceration differs from the usual driver deceleration injury in that no attenuation of force on the victim occurs at the time of impact. Traction-torsion forces on the aorta at points of fixation and increased intraluminal aortic pressure are the likely mechanisms of rupture. Adequate angiographic evaluation of these patients requires visualizing the entire aortic arch from aortic valve to diaphragm.
升主动脉损伤的影像学评估很少见，因为此类损伤几乎总是会立即导致死亡。我们报告了3例经血管造影研究的升主动脉撕裂病例，并对相关文献进行了回顾，同时讨论了损伤机制。导致升主动脉撕裂的减速性创伤类型不同于常见的驾驶员减速损伤，其在撞击时不会使受害者所受的力减弱。主动脉固定点处的牵张 - 扭转力以及管腔内主动脉压力升高可能是破裂的机制。对这些患者进行充分的血管造影评估需要从主动脉瓣到膈肌对整个主动脉弓进行显影。
