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.
Observational (n=118)
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. (Wed,) conducted a 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.
