Innominate artery aneurysms are an uncommon pathology. There are several pathogenic mechanisms involved in their formation, and patients are usually asymptomatic. However, different clinical presentations are possible. Management varies according to anatomic characteristics. Surgical treatment is recommended in order to avoid complications. We present a case of a patient with an innominate artery aneurysm found incidentally during surgery for myocardial revascularization. A 77-year-old male with unstable angina secondary to multivascular ischemic heart disease was subjected to surgery. Coronary angiography did not evaluate the aortic arch and its branches. During the surgical procedure we found a 2-cm saccular aneurysm at the origin of the innominate artery. After completing the revascularization procedure and once the patient was no longer on cardiopulmonary bypass, aneurysmorrhaphy was successfully done.
无名动脉动脉瘤是一种罕见的病理情况。其形成涉及多种致病机制，患者通常无症状。然而，也可能有不同的临床表现。治疗方法因解剖特征而异。为避免并发症，建议进行手术治疗。我们报告一例在心肌血运重建手术中偶然发现的无名动脉动脉瘤病例。一名77岁男性，因多支血管缺血性心脏病继发不稳定型心绞痛而接受手术。冠状动脉造影未评估主动脉弓及其分支。在手术过程中，我们在无名动脉起始处发现一个2厘米的囊状动脉瘤。完成血运重建手术后，待患者脱离体外循环，成功进行了动脉瘤缝合术。
