RESUMO
Objective To study the efficacy and safety of carotid endarterectomy ( CEA) in the treatment of carotid artery stenosis with different neurological deficits .Methods The clinical data of 59 patients with carotid stenosis treated by carotid endarterectomy in the department of neurosurgery of affiliated hospital of Xuzhou medical university from September 2015 to February 2017 were analyzed retrospectively ,a total of 62 operations were performed in these patients ( including 3 patients accepted bilateral operation ) .According to the preoperative 1 day nerve function which evaluated by the modified Rankin scale (mRS)score,they were divided into mRS <3 group(n=47),mRS≥3 group (n=15).They were followed up for 6 to 24 months,the neurological function of 62 patients was scored again by mRS at 6 months after sur-gery.The clinical data and the difference of surgical efficacy and safety of perioperative period between the 2 groups were analyzed and com-pared.Results The 62 times of operations were successful in patients .The neurological function of the 2 groups were significantly improved compared with the preoperative,the difference was statistically significant(P<0.05).In the mRS≥3 group,there were 1 patients with perio-perative cerebral infarction died of cerebral hernia ,1 case of consciousness disorder caused by high perfusion and 1 cases of postoperative in-tracranial hemorrhage caused by high perfusion .In the mRS<3 group,there was 1 case left contralateral hemiplegia caused by a large area of cerebral infarction .The incidence of cerebral apoplexy within 30 days after procedure in the mRS≥3 group was significantly higher than that in the mRS<3 group.There was no new stroke in 61 patients during the long-term follow-up.Conclusion Mild(mRS<3) and severe(mRS≥3) of patients has improved nervous function from CEA;perioperative risk of patients with severe neurological deficits is relatively higher , but the preventive effect for the prevention of ischemic stroke recurrence is worthwhile .
