Abstract
JVIR 2000; 11:1005–1008 BY many, pulmonary angiography is still considered the gold standard in the diagnosis of pulmonary embolism. Traditionally, pulmonary angiography had been performed with use of 6–8-F pigtail, or modified pigtail, catheters and cut-film technique. More recently, digital subtraction angiography has been used to study the pulmonary arteries, and has been shown to have a diagnostic accuracy at least as good as cut-film angiography (1,2). With more frequent use of digital subtraction angiography and its better contrast resolution, pulmonary angiography can usually be performed with smaller amounts of contrast material and lower injection rates. Improvements in catheter design now allow for higher flow rates with smaller catheter sizes. Despite these advances, pulmonary angiography is still usually performed with larger catheter sizes. In this study, we report our experience with use of the 5-F Omniflush (SoftVu; Angiodynamics, Queensbury, NY) catheter for pulmonary angiography.
