目的:探讨主动脉破裂的CT影像表现.方法:回顾性分析10例经临床检查或手术证实的主动脉破裂病例的CT表现.所有病例均行螺旋CT增强扫描.分析主动脉破裂的部位、大小、有无造影剂渗出、主动脉周围有无血肿形成、血肿及其与周围脏器等关系.结果:10例主动脉破裂中,胸主动脉破裂2例,腹主动脉破裂8例,其中主动脉夹层破裂1例,主动脉瘤破裂9例.CT增强扫描显示破口4例,主动脉周围血肿形成10例,活动性造影剂喷射3例,附壁钙化血栓中断4例.血肿的形态和部位与解剖和出血速度有关.结论:增强CT扫描是确诊主动脉破裂的重要手段.%Objective: To describe the CT appearance of aortic rupture. Methods:The clinical data of 10 patients with aortic rupture proved by surgery or clinical were analyzed retrospectively. The location and size the aortic rupture, contrast medium active extravasations and adjacent tissue relation with hematoma were analyzed. Results: Ten patients, including two thoracic aortic rupture,eight abdominal aortic rupture. Which one case aortic dissection and nine cases aortic aneurysm, Contrast-enhanced CT displayed rupture hole in three cases. All cases were observed with Per aortic hematoma. Three cases were jet-like extravasations. Four cases showed wall calcification discontinuity. The shape and location of hematoma was correlated with anatomy and speed of hemorrhage. Conclusions:The aortic rupture confirmed by enhanced CT was the most important means.
