An IV digital subtraction angiography (DSA) is a procedure that shows your blood vessels by using contrast dye in a vein. It takes less time and has less risk than an angiogram. This test can show artery narrow spots, vessel changes, or brain aneurysms.
Before the Procedure
A nurse will call you once the procedure is scheduled. They will ask you to review your medicines and any allergies you have. You may need lab work before the test.
You will get a second call 2–3 days before the exam. They will let you know what time to arrive and tell you what medicines to stop before surgery.
Diet
You may eat and drink as normal.
During the Procedure
You will change into a gown, and we will place an IV in your arm.
A doctor will go over details of the exam and answer any questions.
We will take you to the angiogram suite.
You will lie flat on a table that moves. We will ask you to be completely still.
We inject contrast dye through the IV in your arm.
We use X‑ray to take images before and after the dye goes in. A computer removes the bone images so we can see only the dye in your vessels.
After the Procedure
You will go back to the prep and recovery area. A nurse will remove your IV and help you change your clothes. You can go home right away. You should see the doctor who ordered your test to review your results.
Results
