Angiogram of the Head and Neck
How It Is Done continued...
An angiogram takes 1 to 3 hours.
After the test
catheter is taken out after the angiogram, and pressure is put on the needle
site for 10 to 15 minutes to stop any bleeding. A small sandbag or clamp may be
put on the site to hold pressure. A bandage is put on the site. You will be
given pain medicine if you need it.
If the catheter was put in a
vessel in your arm, you should not have any blood taken from that arm or your
blood pressure measured in that arm for several days. You will rest in bed
after the test for several hours. If the catheter was placed in the groin area,
try to keep that leg straight for 8 hours. Your doctor will give you specific
instructions after the test. You can use an ice pack on the needle site to
relieve pain and swelling.
The place in your hands and feet where
your heartbeat (peripheral pulse) can be felt may be marked with a pen. Your
pulse may be checked before and after the angiogram.
