ABSTRACTObjective To evaluate the long-term safety, efficacy, and prognosis of endovascular treatment in patients with subclavian artery stenosis or occlusion (SAS/SAO). Methods This single-center, retrospective study analyzed 232 consecutive patients undergoing endovascular treatment for SAS/SAO between June 2017 and June 2024. The endpoints included technical success, complication rate and freedom from cardiovascular death (CVD), restenosis, and re-intervention. Multivariable analysis was performed to determine independent predictors. Results Technical success rate was significantly higher in stenoses than in occlusions (99.4% versus 90.8%, p Conclusion Endovascular treatment is a safe and effective revascularization strategy for subclavian artery stenosis or occlusion, demonstrating favorable long-term patency and low complication rate. The study identifies risk factors for CVD, restenosis and re-intervention, which may benefit the management for patients at risk.
