Alternative Names

What the risks are:

There is the possibility of significant complications, including:

  • Allergic reaction to the contrast dye
  • Blood clot or bleeding at the needle stick site, which could partly block blood flow to the leg
  • Damage to an artery or artery wall from the catheter, which can block blood flow and cause a stroke (rare)

Tell your health care provider immediately if you have:

  • Facial weakness
  • Numbness in your leg during or after the procedure
  • Slurred speech
  • Vision problems
