Digital pulmonary arteriography identified pulmonary emboli in 75% of positive exams, and balloon-occlusion cineangiography demonstrated emboli missed by standard studies in 4 of 40 patients.

Do digital pulmonary arteriography and balloon-occlusion cineangiography improve the identification of pulmonary emboli compared to standard imaging?
Digital pulmonary arteriography and balloon-occlusion cineangiography serve as valuable adjunctive imaging techniques to standard pulmonary arteriography and perfusion scans for detecting pulmonary emboli.
The value of digital pulmonary arteriography and balloon-occlusion cineangiography was investigated in 118 selected patients. In one series of 40 patients, digital pulmonary arteriography correctly identified pulmonary emboli in 20 (75%) of 26 positive examinations when interpretation was confined to the first three divisions of the pulmonary artery. In a second series of 78 patients with peripheral radionuclide perfusion scan defects, 40 of whom had pulmonary emboli, adjunctive balloon-occlusion cineangiography demonstrated emboli in four patients not seen on standard selective catheter pulmonary magnification studies with cut films. These two procedures (i.e., digital pulmonary arteriography and balloon-occlusion cineangiography) are important adjuncts to radionuclide perfusion scans and selective catheter pulmonary arteriography in the evaluation of patients with pulmonary emboli.
Ferris et al. (1984) conducted an observational in Pulmonary emboli (n=118). Digital pulmonary arteriography and balloon-occlusion cineangiography vs. Standard selective catheter pulmonary magnification studies with cut films was evaluated on Identification of pulmonary emboli. Digital pulmonary arteriography identified pulmonary emboli in 75% of positive exams, and balloon-occlusion cineangiography demonstrated emboli missed by standard studies in 4 of 40 patients.
