  RESULTS
  Data showed that: (1) the incidence of pulmonary embolism increased from 0.09‰ to 1.12‰ while the mortality dropped from 73.3% to 12.0%; (2) major risk factors would include thrombosis of deep veins, surgical operations, heart diseases, varicosity or phlebitis of lower extremities, trauma and fracture etc., according to the order of incidence rates. Surgical operations had become the second major risk factor in the last 10 years.
