Carotid stenosis, X-ray of the left artery

Carotid stenosis, X-ray of the right artery

Vertebral angiogram; Angiography - head; Carotid angiogram

There is the possibility of significant complications:

• A reaction to the contrast dye can occur.
• There is some risk of the catheter damaging the artery or knocking loose a piece of the artery wall, which can block blood flow and cause a stroke. This is rare, however.
• A clot or bleeding at the puncture site may result in a partial blockage of the blood flow to the leg.

Let your health care provider know immediately if you have:

• Facial weakness
• Slurred speech
• Visual trouble
• Numbness in your leg during or after the procedure
