Malignant peripheral arterial emboli are extremely unusual. Most reported cases of malignant arterial emboli are secondary to invasion of the systemic circulation by pulmonary malignancies via the pulmonary veins. We report a rare case of a primary sarcoma of the aortic arch that presented as malignant emboli. When confronted by a patient with malignant emboli, a normal chest radiograph, and no evidence of a right-to-left shunt, a primary malignancy of the aorta should be suspected and angiography should be performed.
恶性周围动脉栓子极为罕见。大多数报道的恶性动脉栓子病例是肺部恶性肿瘤经肺静脉侵犯体循环所致。我们报告一例罕见的主动脉弓原发性肉瘤表现为恶性栓子的病例。当面对有恶性栓子、胸部X线片正常且无右向左分流证据的患者时，应怀疑主动脉原发性恶性肿瘤并进行血管造影。
