Abstract
Background: Endovascular intervention is a minimally invasive method of treatment of subclavian artery stenosis cases in whom there is indication for revascularization. Objective: (1) To describe clinical and subclinical characteristics of patients with atherosclerotic subclavian artery stenosis and, (2) Evaluation of early results and safety of endovascular intervention for subclavian artery stenosis. Materials and method: From July 2019 to September 2020, we conducted the study on 31 subclavian artery stenosis cases in whom endovascular intervention was performed. Follow-up examinations were performed routinely at 1 month, 3 months, and 6 months post-intervention. Results: Demographic features of the studied population (27 males and 4 females, aged from 59 to 86, mean age was 68,71±7,043). 21 patients (67.7%) had subclavian steal syndrome, 10 patients (32.2%) had upper limb ischemia, 8 patients (25.8%) had both features, and 2 patients (6.5%) had ipsilateral AFV. Interventions were successful in 29 patients (93.5%), 29 stents were used. In 2 cases (6.5%), interventions were unsuccessful because of complete occlusion of the subclavian artery. Clinical success was 29 patients (93.5%), clinical failure was 2 pantients (6,5%). No restenosis was observed during follow-up examinations at 1, 3, 6 months post-intervention. Only 1 case with restenosis was recorded 22 months after stenting. Survival rate at 1, 3, 6 months post-intervention were 100%, 1 patients died from lung cancer at 12 month. Conclusion: Endovascular intervention of atherosclerotic subclavian artery stenosis is a safe and effective method of treatment.
