Endovascular stent grafting (EVSG) is a minimally invasive alternative to open repair of thoracic aortic aneurysms. It is useful in the treatment of thoracic aneurysms, dissections, and ruptures. Currently, the incidence of thoracic aortic aneurysms is 6:100,000 people. Comorbidities often include hypertension, coronary artery disease, chronic obstructive pulmonary disease, peripheral vascular disease, and cerebrovascular disease, and there often is a history of smoking. Without surgical intervention, a high risk of mortality exists, primarily due to aneurysm rupture. Due to the complexity of performing open surgical repair of the thoracic aorta and its associated morbidities such as paraplegia, renal failure, stroke, and prolonged ventilator support, new approaches to thoracic aneurysm repair are being investigated. When compared with open repair, stent grafting is a palliative rather than a curative treatment, and the risk of aneurysmal rupture still exists. This article describes a patient who underwent EVSG who had a history of abdominal aortic aneurysm repair and a known bovine arch.
血管内支架植入术（EVSG）是一种用于胸主动脉瘤开放修复的微创替代方法。它在治疗胸主动脉瘤、夹层和破裂方面很有用。目前，胸主动脉瘤的发病率为每10万人中有6例。合并症通常包括高血压、冠状动脉疾病、慢性阻塞性肺疾病、外周血管疾病和脑血管疾病，并且常有吸烟史。未经手术干预，存在较高的死亡风险，主要是由于动脉瘤破裂。由于进行胸主动脉开放手术修复的复杂性及其相关并发症，如截瘫、肾衰竭、中风和延长呼吸机支持时间，正在研究胸主动脉瘤修复的新方法。与开放修复相比，支架植入术是一种姑息性而非治愈性治疗，动脉瘤破裂的风险仍然存在。本文描述了一名接受EVSG治疗的患者，该患者有腹主动脉瘤修复病史且已知为牛型主动脉弓。
