title: [Systemic complications of functional endoscopic sinus surgery in patients with chronic rhinosinusitis].
abstract: OBJECTIVE
  To analyses the causes and prevention of systemic complications of functional endoscopic sinus surgery (FESS) in patients with chronic rhinosinusitis.
  
  
  METHODS
  Three typical cases were reported including their medical history, preoperative diagnosis, medications during preoperational period, complications and treatment. The causes and preventive measures of systemic complications were analyzed.
  
  
  RESULTS
  Three patients were all suffered from chronic rhinosinusitis with nasal polyps (CRSwNP). After FESS, 1 case was complicated with coma and hyponatremia, 1 case with acute myocardial infarction, and 1 case with lower extremity deep venous thrombosis. The patient with coma and hyponatremia was soon waked after intravenous infusion of 10% sodium chloride. Two patients with acute myocardial infarction and lower extremity deep venous thrombosis were soon completely rehabilitated after emergency thrombolytic therapy and endovascular intervention. Three patients were completed recovered from their systemic complications without any severe sequela.
  
  
  CONCLUSIONS
  Systemic hemostatic drugs should be banned in patients with hypercoagulable state in perioperation period of FESS in order to avoid severe systemic complications. Timely vascular interventional treatment can prevent severe sequels.
