selective angiography

Also found in: Dictionary, Thesaurus, Encyclopedia.

se·lec·tive an·gi·og·ra·phy

angiography in which visualization is improved by concentrating the contrast medium in the region to be studied by injection through a catheter positioned in a regional artery, for example, coronary angiography.

selective angiography

a radiographic procedure that allows selective visualization of the aorta, the major arterial systems, or a particular vessel. It is performed after a few milliliters of a radiopaque contrast medium has been injected through a percutaneous catheter. The patient is observed for signs of sensitivity to the contrast medium, including chills, tremor, and shortness of breath. After the procedure the catheter is withdrawn, and pressure is placed on the puncture site to prevent bleeding. Blood pressure is checked every 15 minutes for 2 hours.

selective angiography

Angiography in which a catheter is introduced directly into the vessel to be visualized.
See also: angiography


radiological demonstration of certain areas of the vascular system by the injection of a radiopaque solution (arteriography, lymphangiography or phlebography).

brain angiography
radiography of the cranium after the intravenous injection of a radiopaque substance. An area of poor vascularity indicates the presence of a space-occupying lesion in the brain.
fluorescein angiography
intravenous fluorescein can be visualized in retinal and iris vasculature with the use of blue filters and direct or indirect ophthalmoscopy or photography. See also vitreous fluorophotometry.
nonselective angiography
injection of contrast material into a regional vessel or the general circulation.
orbital angiography
contrast study of the arteries of the orbit, particularly the malar, infraorbital, maxillary and dorsal orbital, using the infraorbital artery for injection of a suitable medium.
pulmonary angiography
demonstration of pulmonary veins and arteries by introduction of contrast material into the jugular or cephalic vein or via a catheter positioned in the pulmonary artery.
renal angiography
outlines renal blood flow, usually via a catheter introduced into the femoral artery and passed retrograde into the aorta to the vicinity of the renal arteries.
selective angiography
placement of the catheter in the vessel or heart chamber being studied in order to provide the best possible contrast study of the suspected lesion.
