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.

The dual approach of studying blood flow with angiography and directly visualizing the interior of the artery with angioscopy is useful because angiography shows functional improvement but does not provide detailed information about the condition of the blood vessel wall.
Images can be displayed in Volume Rendering Technique (VRT), as stereo views, or as virtual angioscopy (Fly-through option).
Angiography is useful because it shows functional improvement, while angioscopy shows the actual condition of the vessel and how cleanly the clot has been cleared.
