Dealing with symptomatic stenosis of the subclavian artery: Open or endovascular approach? A case report.

INTRODUCTION

Stenosis of the subclavian artery is uncommon and it rarely causes symptoms. Only symptomatic patients should be treated.

PRESENTATION OF CASE

We report a case of chronic left upper limb ischemia caused by subclavian artery stenosis after repetitive clavicular fixation. The stenosis was first treated with carotid-subclavian bypass and soon followed by angioplasty and stenting of the subclavian artery because of occlusion of the bypass. Finally, failure of these procedures necessitated a subclavian-axillary crossover bypass.

DISCUSSION

Both extra-anatomic bypass and percutaneous transluminal angioplasty are safe and effective. If feasible, many authors use endovascular treatment. According to literature, extra-anatomic bypass still remains the first choice of treatment for symptomatic patients. However, the introduction of routine stent implantation is equalling these results. Because of its lower long-term patency rate, endovascular treatment is favorable for patients at high risk.

CONCLUSION

Our case is a good example of difficulties involved in choosing the best treatment option for subclavian artery stenosis.
