title: [Effectiveness analysis of carotid endarterectomy in diabetic patients suffering from carotid stenosis].
abstract: OBJECTIVE
  To evaluate the perioperative complications and effectiveness of carotid endarterectomy (CEA) with diabetes mellitus (DM).
  
  
  METHODS
  A total of 148 patients with carotid stenosis undergone CEA from December 2010 to December 2013 were collected and analyzed retrospectively. The patients were distributed into DM group (n=83) and the control group (n=65) according to the comorbidities. Age, gender, risk factors, stenosis degree, cerebral ischemic symptom, shunt in operation, perioperative complications and restenosis after one year in the two groups were analyzed and compared.
  
  
  RESULTS
  There were no statistical difference between the two groups in terms of the general characteristic, clinical ischemic symptoms, concomitant disease, operative time, the amount of bleeding, the ratio of shunt (P>0.05). The rates of perioperative complications observed in DM group, including postoperative infection, neck hematoma, cranial nerves injured, acute cardiac infarction, stroke, hyperperfusion syndrome, all-cause mortality and one year restenosis after operation were 7.2%, 12.0%, 10.8%, 3.6%, 6.0%, 9.6%, 2.4% and 9.6% respectively. The complication rates observed in the control group, on the other hand were 3.1%, 9.2%, 4.6%, 1.5%, 4.6%, 7.7%, 1.5% and 3.1% respectively. There were no significant statistical difference between the two groups (χ² =0.551, 0.300, 1.898, 0.069, 0, 0.172, 0.138, 1.559, P>0.05).
  
  
  CONCLUSIONS
  CEA may be safe and effective in diabetic patients suffering from carotid stenosis, on the condition that the blood glucoses of the patients are controlled well, and the cardio cerebral vascular system is carefully assessed and intervened before the operation.
