Revascularization of the Subclavian Artery

Abstract

Introduction: The incidence of stenosis of the subclavian artery represents 3-4% of the general population; atherosclerosis is the most common cause. We conducted this study to review the stenocclusive pathology of the subclavian artery, and to expose our experience in surgical and endovascular management. Material and methods: It is a retrospective and analytical study conducted within the department of vascular surgery of Mohammed VI CHU concerning four observations of patients hospitalized between September 2014 and October 2016 for symptomatic subclavian artery stenosis. Results: The average age of our patients was 78 years, 3 women and one man; atheroma was the cause of the stenosis in all cases. Surgical treatment consisted of subclavio-carotid transposition in 2 cases, carotid-bypass grafting in one case and angioplasty with stent placement in the latter case. Conclusion: It is important for the surgeon to have a thorough understanding of the anatomy and etiology of subclavian artery stenosis, while considering the surgical options. This case series presents some of the treatment options available to vascular surgeons for the management of symptomatic subclavian artery disease.
