Catheter Angiography
Procedure Description:
Angiography is the gold standard to study the blood vessels supplying
the brain. The procedure involves placing a catheter, usually through
a small incision in the groin, in the blood vessels leading to the
brain. Thereafter, contrast dye is injected into these blood vessels.
As the dye flows through the arteries and veins of the brain, sequential
x-rays are taken. Typically, this test provides exquisite pictures
of the blood vessels going and coming from the brain.
