Carotid endarterectomy for symptomatic carotid artery near-occlusion / 中华普通外科杂志

ABSTRACT

Objective:To investigate the effect of carotid endarterectomy(CEA) in the treatment of symptomatic carotid artery near-occlusion(CNO).Methods:Clinical symptoms, imaging examination, treatment and prognosis of 122 symptomatic CNO patients admitted to China-Japan Friendship Hospital from Jan 2014 to Jan 2020 undergoing CEA were retrospectively analyzed. Patients were divided into two groups based on the collapse condition,full collapse group(54 cases) and non-full collapse group(68 cases).Results:The difference was insignificant between the two groups at the 30-day and 12-month occurrence rate of primary endpoints(1.85% vs. 4.41%, P=0.629;7.41% vs. 4.41%, P=0.698).Postoperative re-stenosis occurred in one case in the non-full collapse group 8 months after CEA. Conclusions:CEA can achieve good curative effect for patients with CNO with recurrent symptoms, irrelevant to the existence of distal full collapse. The shunt can prevent intraoperative hypoperfusion and postoperative hyperperfusion.
