Introduction: Subclavian stenosis has a prevalence of approximately 2% in the community, and 7% within a clinical population. It is closely linked with hypertension and smoking. There is a relative paucity of published data to inform clinicians on the optimal mode of treatment for subclavian artery stenosis.Objectives: To compare clinical outcomes of subclavian bypass surgery with that of subclavian endovascular re-vascularisation. Endpoints were survival time, re-intervention-free survival, and symptom-free survival.Method: In all, 21 subclavian interventions were performed from 2000 to 2010. We compared angioplasty vs angioplasty with stenting vs bypass.Results: Technical success was 100% in all groups. Symptom-free survival, at 70 months, was 60% in the angioplasty group, 100% in the angioplasty and stenting group and 75% in the bypass group. Re-intervention rate was 40% in the angioplasty group, 0% in the angioplasty and stenting group and 25% in the bypass group. Median time for re-intervention was 9.5 months in angioplasty patients and 36 months in bypass patients (p = 0.102). Target lesion revascularisation was 20.0% for angioplasty procedures, 16.67% for angioplasty and stenting and 25% for bypass procedures.Conclusion: Angioplasty with stenting provides improved symptom-free survival and freedom from re-intervention in patients with symptomatic subclavian artery stenosis.
