Peripheral Angioplasty & Stenting
Peripheral AngioplastyPeripheral angioplasty is a minimally invasive procedure where a catheter with a balloon tip is inserted into a peripheral artery (arteries in the lower abdomen, kidneys, arms, legs or feet) and inflated to compress plaque buildup. This procedure is performed in a state-of-the-art cardiovascular catheterization laboratory. A catheter is inserted into a blood vessel in the upper thigh (groin) or arm. Using high-resolution fluoroscopic (X-ray) video and film equipment, the catheter is guided through to the peripheral artery that is being treated. Once the catheter is in place the balloon is inflated and the narrowed peripheral artery is stretched open. The fatty plaque or blockage is pressed against the peripheral artery walls enlarging the diameter of the peripheral artery. After the blocked area of the peripheral artery is widened the balloon is deflated and removed. Blood flowing through the peripheral artery is increased, supplying blood to the heart.
Peripheral Stent ImplantsPeripheral stents are often implanted in conjunction with balloon angioplasty. Peripheral stent implants help hold open an artery so that blood can flow through the blocked or clogged artery, and may be used to repair an aneurysm. The stent—a small, lattice-shaped wire mesh tube, props open the artery and remains permanently in place. The stent is passed through the catheter and implanted in the peripheral artery.
Recent development in stent devices has been made to help prevent restenosis, the reoccurrence of the narrowing of a blood vessel. Drug-eluting stents (DES) are coated with medication, which is actively released to the artery.
These procedures are performed in a cardiovascular catheterization laboratory, with local anesthesia. An IV (intravenous line) into your arm or hand will provide you with medication to make the procedure as comfortable as possible.
