Abstract
BACKGROUND:Carotid artery stenting is a minimal y invasive, safe, simple intervention, which is particularly meaningful to patients with carotid artery stenosis who exhibit poor physical basis and cannot tolerate open surgery. <br> OBJECTIVE:To explore the clinical effect of percutaneous transluminal angioplasty and stenting for treatment of extracranial carotid artery stenosis. <br> METHODS:Twenty-nine patients with extracranial carotid artery stenosis, including 19 males and 10 females, age ranging from 45-78 years, were enrol ed and subjected to stenting and percutaneous angioplasty. American National Institutes of Health Stroke Scale, modified Rankin Scale and CT examination were tested before treatment and 24 hours after treatment. After 3-12 months fol ow-up, the coagulation indexes and B ultrasound of the carotid artery were reviewed. <br> RESULTS AND CONCLUSION:One patient exhibited the complete bifurcation occlusion of the right common carotid artery, and only the diameter of external carotid artery recovered 50.0%. The remaining patients were confirmed by angiograph that completely restored to normal levels, and the success rate was 97%. At 24 hours after treatment, al the 29 patients exhibit significant improvement in the diameter of lesioned carotid artery, scores on American National Institutes of Health Stroke Scale and modified Rankin Scale (P<0.01, P<0.05). During the 3-12 months fol ow-up, no cerebral infarction and transient cerebral ischemia occurred and carotid artery stenosis was improved in al patients. At 6 months after operation, one patient had restenosis, and the restenosis rate was 3%. Percutaneous angioplasty combined with biological material stenting for treatment of extracranial carotid artery stenosis can obtain good clinical effects.关键词
