angioscopy

angioscopy

 [an″je-os´kah-pe]
1. use of a fiberoptic angioscope to visualize the lumen of a blood vessel.
2. visualization of capillary blood vessels with a special microscope (angioscope).

(an'jē-os'kō-pē),
1. Visualization with a microscope of the passage of substances (for example, contrast media, radiopaque agents) through capillaries after intravenous injection.
2. Visualization of the interior of blood vessels, especially the pulmonary arteries, using a fiberoptic catheter inserted through a peripheral artery.

angioscopy

Direct visual examination of the inside of a blood vessel during life. Modern angioscopes are fine, fibre-optic catheters capable of passing into the coronary arteries so that the state of their inner walls may be ascertained. This procedure, however, is not without risk.
