We found that 41%of patients(118/291)were asymptomatic.Surgical indications were appropriate in 33%of cases(92/281),uncertain in 49%(138/ 281)and inappropriate in 18%(51/281).Stroke or death occurred within 30 days postoperatively in 5.2%(9/174)of symptomatic patients and 5.1%(6/117) of asymptomatic patients.At least one cardiac complications(angina, congestive heart failure,dysrhythmia or myocardial infarction)developed in 8.9%(26/291).Independent preoperative risk factors for stroke or death were histories of angina or congestive heart failure and lack of antiplatelet medication;for cardiac complications,risk factors were age>75 years and a history of congestive heart failure.Almost 1 in 5 patients underwent CEA inappropriately,which was most commonly due to apparent overestimation of stenosis severity,and half had uncertain indications.Our high complication rate possibly negated any overall surgical benefit in the large group of asymptomatic patients. |
