Carotid axillary artery bypass: an option following failed open and percutaneous procedures
Insights
Carotid-subclavian bypass is crucial for brachiocephalic stenosis due to re-stenosis after angioplasty. This report details an underused technique for upper extremity revascularization after failed endovascular and open procedures.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
Background:
- Percutaneous transluminal angioplasty and stenting are increasingly used for brachiocephalic circulation stenosis.
- Intimal hyperplasia and re-stenosis limit the efficacy of these endovascular procedures.
- High re-stenotic rates are observed in long-term studies of subclavian or innominate artery lesions.
Observation:
- Carotid-subclavian bypass remains a significant open surgical option.
- Alternative revascularization methods are needed, especially after endovascular or open technique failures.
- This report presents an underused technique for upper extremity revascularization.
Findings:
- The described technique offers a solution for complex cases.
- It provides an alternative when standard methods fail.
Implications:
- This underused method could improve outcomes for patients with challenging brachiocephalic or upper extremity arterial disease.
- It expands the armamentarium for treating complex vascular stenosis.
- Further investigation into this technique's long-term efficacy is warranted.
Abstract:
Percutaneous transluminal angioplasty and stenting is being employed with increasing frequency for stenosis involving the brachiocephalic circulation. However, the efficacy of these procedures is limited by intimal hyperplasia and subsequent re-stenosis. Long-term results for treating lesions of the subclavian or innominate artery have shown significant re-stenotic rate. Accordingly, carotid-subclavian bypass remains as an important procedure. Alternative methods may still be required, particularly after failure of open re-vascularization and percutaneous techniques. This report describes an underused technique that enables upper extremity revascularization following prior attempts at endovascular and standard open techniques.
