    Abstract:
    PURPOSE: To assess the safety and efficacy of carotid artery stenting (CAS) of the left internal carotid artery (LICA) from a right radial/brachial approach in patients with bovine aortic arch. METHODS: Among 505 consecutive CAS patients treated at our facility between June 2007 and December 2012, 60 (11.9%) patients (44 men; mean age 73±9 years) with LICA stenosis and bovine arch were treated from a right radial (n=32) or brachial (n=28) approach. Three quarters of the patients had characteristics qualifying them at high surgical risk; 52 were asymptomatic. The types of cerebral protection (a distal filter or proximal MO.MA system), stent, and technique were at the operation's discretion. RESULTS: The radial/brachial approach was successful in 59 (98.3%) of 60 procedures; 1 case was converted to a femoral approach. Proximal protection was used in 15 cases (11 brachial, 4 radial) with severe, soft plaques, although the MO.MA system proved too short in a tall patient having a radial approach and a filter was used. Clinical success with no adverse events was 96.7% owing to 1 retinal embolism and 1 minor stroke. Vascular complications occurred in 2 (3.3%) brachial group patients. No major bleeding was encountered. Over a mean follow-up of 18.7±17.5 months, midterm event-free survival was 93%. No target vessel revascularization was necessary. CONCLUSION: CAS via a right radial or brachial approach is safe and effective in patients with LICA stenosis and types 1 or 2 bovine arch.
