title: [Clinical pathological study on 23 pulmonary embolism proved by autopsy].
abstract: OBJECTIVE
  To improve the early diagnosis of pulmonary embolism.
  
  
  METHODS
  The clinical and pathological data of 23 cases of autopsy-proved pulmonary embolism in Beijing hospital from 1951 to 1994 were reviewed.
  
  
  RESULTS
  23 patients: male 18, female 5, age ranged from 34 to 82 years. Misdiagnosis rate was 87%. The unexplained dyspnea, chest pain, sudden onset dyspnea and sudden death were the most frequent symptoms. Arterial blood gas data frequently demonstrated hypoxia and hypocapnia. The most important causes of an incorrect diagnosis could be the failure of suspecting pulmonary embolism, because of the variability of clinical manifestation and the presence of other concomitant diseases.
  
  
  CONCLUSIONS
  All patients with otherwise severe unexplained dyspnea or chest pain have to be sent for perfusion lung scintigraphy, accordingly, underdetection of pulmonary embolism and mortality of pulmonary embolism could be reduced.
