Various surgical techniques of the aorta result in expected imaging appearances on CT images that resemble complications such as pseudoaneurysm, perigraft abscess, and dissection. Awareness of these techniques, understanding the clinical situation in which they are performed, and familiarity with the typical appearances and locations of these mimics are essential for accurate interpretation. CT imaging techniques such as electrocardiographic gating and inclusion of a precontrast series can help distinguish an expected postsurgical finding from a complication. Information in the medical record, particularly the operative note, can clarify challenging cases with unusual imaging features. This review article provides examples of expected postsurgical findings at CT mimicking complications. © RSNA, 2019.
主动脉的各种手术技术会在CT图像上产生预期的影像表现，这些表现类似于诸如假性动脉瘤、移植物周围脓肿和夹层等并发症。了解这些技术、理解实施这些技术的临床情况以及熟悉这些模仿病变的典型表现和位置，对于准确解读至关重要。诸如心电图门控和包含对比剂前系列的CT成像技术有助于将预期的术后表现与并发症区分开来。病历中的信息，尤其是手术记录，可澄清具有不寻常影像特征的疑难病例。本文综述提供了CT上模仿并发症的预期术后表现的示例。©RSNA，2019年。
