The Serrano Kidney and Vascular Access Center (KVAC) of California offers angioplasty and stent placement for patients with circulatory problems that cause swollen legs and arms. Angioplasty with or without vascular stenting is a minimally invasive procedure performed to improve blood flow in the body’s arteries and veins.
In an angioplasty procedure, imaging techniques are used to guide a balloon-tipped catheter, a long, thin plastic tube, into an artery or vein and advance it to where the vessel is narrow or blocked. The balloon is then inflated to open the vessel, deflated and removed.
During angioplasty, a small wire mesh tube called a stent may be permanently placed in the newly opened artery or vein to help it remain open.
