Acute aortic syndromes include aortic dissection, intramural thrombus, and penetrating atherosclerotic aortic ulcer. These are potentially life-threatening abnormalities of the aorta requiring immediate evaluation by the cardio-thoracic surgery service. CT angiography is the most appropriate imaging modality in the acute setting to detect and diagnose the disease and assess its severity. Precontrast and postcontrast imaging should be obtained of the entire aorta from thorax to pelvis. After aortic rupture, the most severe complication is visceral ischemia from hypoperfusion. Dissections should be systematically searched for and may be amenable to endovascular treatment.
急性主动脉综合征包括主动脉夹层、壁内血栓和穿透性动脉粥样硬化性主动脉溃疡。这些都是主动脉潜在的危及生命的异常情况，需要心胸外科立即进行评估。CT血管造影是急性情况下检测和诊断该病并评估其严重程度最合适的成像方式。应获取从胸部到骨盆的整个主动脉的平扫和增强扫描图像。主动脉破裂后，最严重的并发症是低灌注导致的内脏缺血。应系统地排查夹层，其可能适合血管内治疗。
