Most abdominal aortic aneurysms (AAA) and thoracoabdominal aortic aneurysms (TAAA) are asymptomatic and are found on physical exam or incidentally during radiological studies for other indications. These aneurysms are repaired primarily because their risk of rupture increases geometrically as the size exceeds 5 cm. The potential morbidity of intraoperative visceral and spinal ischemia involved with TAAA repair may be reduced with various adjunctive maneuvers.
大多数腹主动脉瘤（AAA）和胸腹主动脉瘤（TAAA）是无症状的，在体格检查时发现，或在因其他指征进行影像学检查时偶然发现。这些动脉瘤主要是因为当大小超过5厘米时其破裂风险呈几何级数增加而进行修复。通过各种辅助措施，可降低TAAA修复术中涉及的内脏和脊髓缺血的潜在发病率。
