Efficacy of carotid endarterectomy in elderly patients with different neurological deficits

Abstract

Objective To analyze the therapeutic effect of carotid endarterectomy (CEA) in elderly patients (>70 years old) with carotid stenosis and neurological deficits. Methods One hundred and twenty-six elderly patients underwent CEA from May 2008 to April 2015, including 7 patients accepted bilateral operation, were chosen in our study. A total of 133 operations were performed in these patients. According to the preoperative modified Rankin scale (mRs) scores, they were divided into a mRs<3 group (n=107), and a mRs≥3 group (n=26). Follow up for 9-18 months, averaged 12.3 months, was performed. Clinical data of these patients were retrospectively analyzed, and operation safety and surgical efficacy were compared between the two groups. Results (1) All operations were successful; the incidence of cerebral apoplexy within 30 d after procedure in the mRs≥3 group was significantly higher than that in the mRs 0.05). (3) During long-term follow-up, 4 occurred restenosis in the mRs 0.05). Conclusion CEA is a safe and effective treatment for the elderly patients with mRs<3; the incidence rate of cerebral apoplexy is high during the perioperative period in mRS≥3 patients, however, long-term follow-up shows that it can prevent recurrent stroke.
