There is hesitancy, based on the perceived risk, to do pulmonary angiography in patients believed to have primary pulmonary hypertension. Yet pulmonary hypertension due to major-vessel, chronic thromboembolism mimics primary pulmonary hypertension clinically and on standard laboratory tests. Because thromboembolic pulmonary hypertension is potentially remediable by thromboendarterectomy and primary pulmonary hypertension is not, differentiating between these disorders is essential. Angiography is required in patients with thromboembolic pulmonary hypertension to define the anatomic location of the thrombi. In evaluating perfusion lung scans of 110 patients with pulmonary hypertension to determine whether the scan might provide a guide to selecting those patients who merit angiography, no segmentalsize perfusion defects were noted on the scans of 64 patients with primary pulmonary hypertension, whereas all 46 patients with thromboembolic hypertension had one or more defects that were segmental in size or larger. These data indicate that a perfusion lung scan should be done in patients with pulmonary hypertension of uncertain cause and that those with one or more segmental or larger defects merit pulmonary angiography before being diagnosed as having primary pulmonary hypertension.
