Application of carotid endarterectomy in the treatment of patients with bilateral moderate to severe carotid stenosis

Objective To evaluate the application of carotid endarterectomy(CEA)in the treatment of patients with bilateral moderate to severe carotid stenosis.Methods We retrospectively analyzed the clinical data of 82 patients with bilateral moderate to severe carotid stenosis who were admitted to our hospital from January 2006 to December 2009.Of these patients,64 underwent ipsilateral CEA and 18 underwent bilateral CEA.Results A total of 100 endarteretomies including 92 patching and 94 carotid shunt were performed.Seventy-six patients smoothly recovered from the surgery.Two patients suffered from cardiac ischemia and infarction and one died of massive cerebral infarction.Three patients presented with hyperperfusion syndrome,and one of them developed cerebral hemorrhage.Of 79 patients who were followed up regularly,76(96.2%)had no cerebral ischemia relevant to the operated carotid artery,one developed mild re-stenosis,and 2 suffered from neurological dysfunction.Conclusion CEA should be performed in patients with bilateral moderate to severe carotid stenosis once the indication is confirmed.
