摘要

主動脈截斷(aortic transaction)為一致命性的傷害，大多由於急性減速之重大衝撞挫傷所造成。約80-90%的病患立即死亡於車禍現場，僅少數存活至醫院，臨床症狀及胸部x光表現不具特異性。因此及時診斷治療刻不容緩，本文報告此一例完全主動脈截斷(complete aortic transaction)之電腦斷層影像表現出罕見卻典型的急性創傷性主動脈緊縮(acute traumatic aortic coarctation)現象，以供參考。

Aortic rupture is a lethal injury readily treatable with prompt diagnosis in those patients who do not succumb at the scene. We report a rare case of complete aortic transection. A 21-year-old male was admitted for compressive chest pain and unstable blood pressure due to traffic accident. The clinical symptom and computed tomography demonstrated a rare but typical sign of ”acute traumatic aortic coarctation” phenomenon. The other CT findings of ruptured aorta in our case included (1) false aneurysm, (2) marginal irregularity of the opacified aortic lumen, (3) periaortic hematoma and (4) extravasation of high density contrast media.
