IR Study Guide Flashcards
What supplies are used for the Seldinger Technique?
a hollow needle (introducer needle), a guidewire, and a catheter
When do you use the Seldinger Technique?
whenever a minimally invasive access to a blood vessel or hollow organ is needed
How to use the Seldinger Technique?
Insert needle into blood flow
advance guidewire through the needle
remove needle leaving guidewire inside vessel
insert sheath/catheter over guidewire and into vessel
remove guidewire
What is digital subtracted angiography(DSA)?
a diagnostic imaging procedure that uses X-rays to image blood vessels.
How does digital subtracted angiography(DSA) work?
A catheter is inserted into a blood vessel
A contrast dye is injected into the blood
X-ray images are taken before and after the dye injection
The first image is subtracted from the second image, making the blood vessels more visible
