Procedural outcome and midterm result of carotid stenting in high-risk patients.
Carotid endarterectomy is the standard treatment for carotid stenosis, but carotid artery stenting has emerged as a potential alternative. Elective carotid artery stenting was performed in 42 patients aged 42 to 79 years (mean, 67.05 +/- 8.67 years) after ultrasonography, computed tomography, magnetic resonance angiography and a neurological evaluation. There was bilateral carotid stenosis in 23 patients (55%), with > 90% stenosis in 18 vessels. All patients had significant associated coronary lesions. An emboli protection device and self-expanding stents were used. One year later, the patients were evaluated by Doppler sonography and selective angiography. Technical success was achieved in all procedures. During follow-up, 1 (2.4%) patient died from myocardial infarction, 1 underwent coronary artery bypass and 14 (40%) had minor complaints including occasional dizziness. No other neurological events were noted. Restenosis was found in one case, but selective angiography ruled out a significant lesion. One patient suffered embolization, but recovered completely within 24 hours. In 7 (17%) patients with type C arch interruption and a tortuous carotid course, stenting was successful and they had no embolization or restenosis. Carotid artery stenting is recommended in high-risk patients.
