目的探讨主动脉壁内血肿CT表现误诊的原因,提高主动脉壁内血肿的诊断水平。方法回顾性分析16例主动脉壁内血肿误诊患者的CT影像资料,总结其图像特点。结果 9例误诊为典型的主动脉夹层,4例误诊为主动脉附壁血栓,3例误诊为主动脉大动脉炎。结论主动脉壁内血肿诊断时应准确把握壁内血肿的影像特点,注意直接征象与间接征象相结合,必要时结合患者病史及多普勒超声等辅助检查可进一步减少误诊情况发生。
Objective To investigate the causes of misdiagnosis of CT findings of intra-aortic hematoma and to improve the diagnosis of intra-aortic hematoma. Methods A retrospective analysis of 16 cases of aortic intramural hematoma misdiagnosed CT image data to summarize the image features. Results 9 cases were misdiagnosed as typical aortic dissection, 4 cases were misdiagnosed as aortic wall thrombosis and 3 cases were misdiagnosed as aortic arteritis. Conclusion Aortic intramural hematoma should be accurately grasped the imaging features of intramural hematoma, pay attention to direct signs and indirect signs combined, if necessary combined with the patient history and Doppler ultrasound and other auxiliary examination can further reduce the misdiagnosis.
