Follow-ups of more than 1 year were carried out in 400 CEAs performed in 372 patients. Perioperative and postoperative clinical features were investigated at 1 month, 1 year and 5 years. Perioperative complications were observed in 6 CEAs (1.5%) whose ADL decreased at 1-5 years. At 1 year, 355 patients maintained preoperative ADL. Poor outcomes were observed in 3 dead patients, 6 patients with surgical complications and an additional 8 patients. The latter 8 patients experienced reduced ADL caused by dementia and poor general condition. Although 223 of 252 patients maintained ADL during the 5-year follow-up, 29 patients experienced reduced ADL mainly due to poor general condition, Parkinsonism or dementia. Ipsilateral stroke was observed in 6 patients. Restenotic changes were detected by ultrasonography in 16 CEAs during 1-3 years and produced TIA in 2 patients. These results indicate CEA without complications can effectively prevent stroke and allow patients to maintain ADL.
