Abstract: | The nonspecificity and variety of clinical features in acute pulmonary embolism account for a high suspicion rate, with a further exclusion of the diagnosis in up to 80% of cases. Arterial blood gas analysis and other laboratory tests are highly nonspecific, and suggestive signs on the electrocardiogram are uncommon. The plain chest X-ray often yields valuable information. Lung scan, when normal, has the great advantage of excluding pulmonary embolism. At present, no procedure has superseded pulmonary angiography to attest the presence of emboli. Angiography will probably gain widespread acceptance with the larger use of thrombolysis. |
