The clinical course of patients with suspected pulmonary embolism and a negative pulmonary arteriogram.
Selective pulmonary arteriography, with superselective magnification views of the lung bases or other areas where abnormalities are shown on perfusion lung scans, performed within 24-48 hours after the onset of symptoms, can effectively rule out clinically significant pulmonary thromboembolism. One hundred and eighty consecutive patients (minimum follow up, six months) with suspected pulmonary embolism and negative pulmonary arteriograms were studied. Not one of the 167 untreated patients died as a result of thromboembolic disease during the acute illness (20 died from unrelated causes), and none of the 147 patients who survived suffered "recurrent embolism" during follow up.
