Abstract:
Objective: To analyze the effectiveness and safety of angioplasty and stenting (CAS) for treatment of high-risk symptomatic carotid arterial stenosis. Methods: A total of 20 patients with high-risk symptomatic carotid arterial stenosis were treated with CAS. Among them, 12 were men and 8 were women, mean age 69 years (62 to 76 years). Of the 20 patients, 11 had TIA and 9 had cerebral infarction. All patients underwent pan-cerebral angiography and it showed that the rate of carotid arterial stenosis >70% according to the North American Symptomatic Carotid Endarterectomy Trial (NASCET) criteria. Among them, 9 patients had unilateral severe carotid arterial stenosis (2 had restenosis after carotid endarterectomy), 6 had bilateral severe carotid arterial stenosis, 5 had unilateral carotid artery occlusion and contralateral severe stenosis (1 was after nasopharyngeal carcinoma radiotherapy). The cerebral protection device and pre-dilation were used in all patients, and the self-expandable stents were used after the pre-dilation. Results: The success rate of the procedure was 100%. The rate of residual stenosis was <30%. AU patients had different levels of transient decrease of heart rate and blood pressure after the procedure. One patient had microembolic infarction, and no other serious complications were found. No other ischemic stroke occurred in the periprocedural period. The reexamination of carotid artery ultrasound after the procedures showed that the stenosis were improved obviously. Conclusion: CAS is less invasive and its perioperative complications is rare. It is safe and effective for treatment of high-risk symptomatic carotid arterial stenosis.
