Subclavian-carotid transposition. Experience in 33 cases

Area of Science:

• Vascular Surgery
• Cardiovascular Medicine

Background:

• Proximal subclavian artery lesions pose a significant clinical challenge.
• Traditional surgical approaches may involve invasive procedures and prosthetic materials.

Purpose of the Study:

• To evaluate the efficacy and safety of subclavian artery transposition for proximal subclavian artery lesions.
• To highlight the advantages of this technique over other treatment modalities.

Main Methods:

• Thirty-three patients with proximal subclavian artery lesions underwent endarterectomy and transposition into the common carotid artery.
• Patient selection was based on comprehensive continuous wave ultrasound Doppler examination.
• Angiography was reserved for specific diagnostic challenges or repeat surgeries.

Main Results:

• The procedure demonstrated a low morbidity rate and zero mortality.
• Vertebral blood flow was normalized in 97% of patients post-operatively.
• The technique offers a short operative time, extra-thoracic approach, and avoids prosthetic material.

Conclusions:

• Subclavian artery transposition is a highly effective and safe method for treating proximal subclavian artery lesions.
• The procedure yields excellent hemodynamic and clinical results, making it the preferred surgical option.
