- Then, a contrast dye is injected into the blood vessel through the catheter. This dye will help the blood vessels to view on the X-ray images.
- X-rays of the blood vessels will be taken.
- Later the catheter will be removed from the large artery.
- Your doctor will review the X-ray images to determine the problem.
What is the postprocedure care/recovery care for Angiography?
- After the completion of the procedure, you may need to stay in the hospital until the sedative wears off.
- Then, your doctor will provide some instructions regarding post-procedure care.
