IVR Terms (cardio) Flashcards
Antegrade
Moving or extending anteriorly, moving with the flow
Angiography
Radiographic visualization of blood vessels following introduction of contrast material
Bifurcation
Division into two branches
Contralateral
Situated on, pertaining to, or affecting the opposite side, as opposed to ipsilateral
Digital Subtraction Angiography
Arteriography using electronic circuitry to subtract the background of bone and soft tissue to provide a useful image of arteries injected with contrast medium
First Order Vessel
Primary branch off the main trunk of a vascular system
Ipsilateral
Situated on, pertaining to, or affecting the same side, as opposed to contralateral
Main trunk of the arterial system
Aorta
Main trunk of the venous system
Vena cava
Non-selective Catheterization
Catheter placed in the main trunk, contrast maybe injected, images may be taken, but the catheter is not moved into any branches
Retrograde
Moving backward or against the usual direction of flow
Roadmapping
Overlaying of two images. A stored image is superimposed upon a current fluoroscopic image, or a current image can be copied for storage or later use in roadmapping. (Angiograms to see landmarks - not diagnostic)
Second order vessel
Secondary branch and comes off the first order vessel
Selective catheterization
A catheter is placed in the branches further off the main trunk (first, second, third or higher order)
Third order and higher vessel(s)
Tertiary branch and further, comes off the second order vessel
