Pulmonary digital subtraction angiography.
Intravenous digital subtraction pulmonary angiography was performed in 220 patients. Of these, 206 had suspected pulmonary embolism. Our intravenous studies yielded images of diagnostic quality in 98% of cases. Compared to conventional pulmonary angiography, intravenous digital subtraction angiography (IV DSA) is safer, faster, and easier to perform. This technique is an acceptable substitute for routine pulmonary angiography in all patients with pulmonary embolism. Intravenous DSA is currently the procedure of choice for the evaluation of patients with suspected pulmonary embolism.
