Abstract

BACKGROUND AND OBJECTIVES: For patients with bilateral carotid artery stenosis, simultaneous bilateral carotid endarterectomy is rarely performed due to a higher perioperative risk for death and strokes. We assessed the immediate and long-term outcomes of simultaneous bilateral carotid stenting (SBCS) for internal carotid stenosis in patients at high surgical risk. MATERIALS AND METHODS: We analyzed 10 patients who underwent SBCS for de novo stenoses of both internal carotid arteries (ICA). Included were those who had 60% to 99% stenosis of extracranial ICAs irrespective of neurologic symptoms and had more than 2 risk factors of Mayo grade III (medical risks) or IV (neurologic risks). RESULTS: The patients had a mean age of 67+/-7 years. Technical success was achieved in all lesions. The mean percent diameter stenosis was reduced from 79+/-13% to 8+/-8%. A total of 21 Wallstents were deployed at 20 lesions. One patient had a minor stroke just after the procedure which was completely resolved with local injection of urokinase. There were no deaths, major strokes or myocardial infarctions during the 30 day follow-up. Six months imaging studies were available on all 9 eligible patients with 18 lesions by duplex sonography and angiography. Late clinical follow-up at a mean of 15.1+/-8.1 months revealed no occurrence of neurologic event or death. CONCLUSION: SBCS is feasible, safe and effective to treat bilateral de novo ICA stenoses in patients at high surgical risk. The procedure, however, is investigational and more experience is required to define its role in the treatment of this patient population.
