lüll The spectrum of pulmonary embolism Clinicopathologic correlations Morpurgo M; Schmid CChest 1995[Jan]; 107 (1 Suppl): 18S-20SPulmonary embolism (PE) is still underdiagnosed even in hospitalized patients. In our recent experience, out of 92 postmortem cases of massive or submassive PE, only 28% were diagnosed before death, whereas the false-positives accounted only for 3% of cases. Similar conclusions have been drawn from large-scale autopsy studies performed in Norway and in the United States. The most important causes of an incorrect diagnosis are failure to suspect PE, and the protean nature of the disease. Remarkable differences actually exist concerning the point of origin and the final localization, as well as the size and age of thromboemboli, the presence or absence of pulmonary infarction, and the underlying pathology. Often a fatal embolus is relatively small but hardly tolerated because of the underlying cardiopulmonary situation. Attention should be called to the frequent autopsy finding of multiple PEs and pulmonary infarctions of apparently different age. This finding is important since it indicates that these patients suffered successive embolizations and the eventual death might have been prevented if an early diagnosis had been made.|Humans[MESH]|Pulmonary Embolism/complications/diagnosis/*pathology[MESH] |
