[A Japanese hospital reports long-term survival for 10 years after carotid endarterectomy].
BACKGROUND
Several reports in Western countries have demonstrated the net benefit and an acceptable long-term survival of carotid endarterectomy (CEA) for severe carotid stenosis. However, long-term follow-up after CEA for carotid stenosis is not well-documented in Japan. The aim of this study was to determine long-term outcomes of CEA in our hospital.


METHODS
38 consecutive patients underwent 42 CEAs at the Kyushu Medical Center between May, 1994 and December, 1998. Survival follow-up was conducted in December 2008 and the incidence of late stroke was investigated in all surviving patients.


RESULTS
A total of 37 CEAs in 30 patients (83.3%) were registered. There were 28 males and 2 females, 25 symptomatic and 5 years asymptomatic, mean ages 68+/-7 years. Survival rate after CEA was 80.0% after 5 and 53.3% after 10-years, respectively. The 10 year survival ratio free from cerebral infarction was 36.7%.


CONCLUSIONS
For the patients in this study, CEA is associated with an acceptable long-term survival as well as a satisfactory benefical effect in stroke prevention.
