    Abstract:
    OBJECTIVE: To assess the efficacy and safety of percutaneous transluminal stenting for patients with carotid artery stenosis. METHODS: Selective percutaneous transluminal stenting was performed for patients with symptomatic carotid artery stenosis (luminal narrowing > or = 70%). Success rates and complications associated with the procedures were observed. During six months of follow-up, both recurrent symptom and restenosis rates were recorded. RESULTS: There were 17 bifurcating lesions among 27 stenoses in 26 patients, of whom 18 had concomitant coronary artery diseases. The acute procedural success rate was 96.3% (26/27), and the degree of stenosis was reduced from 88.6% +/- 8.9% (range 70-100) to 0.4% +/- 2.0% (range 0-10). Six patients developed severe bradycardia and hypotension, and 3 experienced transient loss of consciousness during balloon dilatation. During hospitalization, 2 patients experienced loss of consciousness and convulsion, respectively, due to hyperperfusion, and both recovered 12 hours later. There were 2 minor stroke cases (7.4%) but no cases of major stroke or death. At the 6-month follow-up, there were no cases of TIA or new onset of stroke. There was no restenosis detected in 16 cases using angiography and in 10 cases using MRI in 6 to 16 months of follow-up. CONCLUSIONS: Percutaneous transluminal stenting for patients with carotid artery stenosis has a high procedural success rate with few and acceptable complications. Few patients suffered from recurrent symptoms or showed restenosis in long-term follow-up.
