Patient’s with decreased blood flow in their legs or arms may require peripheral angiography. This procedure involves threading a small plastic tube (catheter) into the effected limb through an artery at the top of the leg. Dye is then injected through the catheter which opacifies the blood vessels and demonstrates any blockages which may be present. If indicated, the blockage can be opened by a balloon (angioplasty) and a small metal device inserted (stent) to keep the vessel open.
Peripheral Angioplasty/Stent Implantation
This procedure, usually performed during a diagnostic peripheral angiography, involves passing a balloon into a region of blockage in a blocked artery. The balloon is then expanded and the blockage opened. In order to keep the blockage from re-forming, a small metal device (stent) is frequently implanted at the same time.
