[Efficacy of axillary-axillary bypass grafting for the subclavian artery disease]

Area of Science:

• Vascular Surgery
• Cardiovascular Procedures

Background:

• Subclavian artery total occlusion presents complex challenges in vascular reconstruction.
• Extrathoracic bypass options include carotid-subclavian, subclavian-subclavian, and axillary-axillary bypasses.

Observation:

• The axillary-axillary bypass procedure was successfully performed in 5 patients with total subclavian artery occlusion.
• Indications included atherosclerosis (3), aortic arch aneurysm rupture (1), and trauma (1).
• All procedures utilized a 6 mm ringed expanded polytetrafluoroethylene graft under general anesthesia.

Findings:

• The axillary-axillary bypass offers superior anatomic exposure compared to other extrathoracic methods.
• This technique avoids interference with critical carotid artery circulation.
• The procedure was found to be minimally invasive and effective for subclavian artery occlusion.

Implications:

• Axillary-axillary bypass is a viable and effective surgical strategy for specific cases of subclavian artery occlusion.
• The choice of bypass technique should be individualized based on patient circumstances.
• This approach represents a less invasive option in the management of complex subclavian artery disease.
