Rationale

The 2022 ACC/AHA Aortic Disease guidelines provide updated recommendations for subclavian artery management, particularly emphasizing its role in TEVAR planning to prevent spinal cord and cerebral ischemia. This addition is crucial for modern vascular surgery practice. I also expanded all abbreviations (LIMA, CABG, AV, TEVAR, LSA) on their first use as per the instructions.

**Intervention thresholds:** Revascularization is indicated for symptomatic patients with subclavian steal syndrome, upper extremity ischemia, or in preparation for LIMA-coronaryleft internal mammary artery (LIMA)-coronary artery bypass grafting (CABG) or AVarteriovenous (AV) fistula creation.creation [@aha2023]. Additionally, subclavian revascularization is recommended in patients undergoing thoracic endovascular aortic repair (TEVAR) when left subclavian artery (LSA) coverage is required to maintain perfusion to the brain, spinal cord, or upper extremity [@aha2023]. Asymptomatic stenosis generally does not require intervention.intervention unless it compromises distal flow in these specific clinical scenarios.
