Abstract：Objective To explore the relationship between increased body mass index(BMI)and complications 30 days after carotid endarterectomy.Methods In this cohort study 398 cases of CEA were conducted in Handan First Hospital and the People's Hospital of Xingtai City from 2012 to 2022,with 138 cases with normal body mass index(18.5-24.9 kg/m2),188 cases with overweight index(25.0-29.9 kg/m2)and 72 cases with obesity index(≥30 kg/m2).Logistic regression analysis was used to evaluate the correlation between overweight or obesity and the early outcomes of carotid endarterectomy.Results Within perioperative period of CEA(30 days),postoperative myocardial infarction was seen in 1 case(0.25%),postoperative stroke and transient ischemic attack(TIA)in 12 cases(3.0%)and postoperative death in 2 cases(0.5%).As for other complications,10 cases bled(2.5%),2 cases had problems in respiratory tract(0.5%),urinary,cardiac and cranial nerve injuries occurred in 2 cases(0.5%),3 cases(0.75%)and 4 cases(1.0%)respectively,and 13 cases(3.3%)needed reoperation.There was no significant difference in perioperative(30 days)results among these three groups,but the frequency of bleeding in overweight patients was significantly lower than that in patients with normal weight(P<0.05).Conclusion Both overweight and obesity indexes were not significantly associated with upregulated mortality,TIA,stroke,myocardial infarction,mild complications or reoperation after carotid endarterectomy,whereas the incidence rate of bleeding in operating area after CEA in overweight patients was significantly downregulated compared with that in patients with normal weight.
