Peripheral Diagnostic and Interventional Procedures (Peripheral Vascular Angiography)
To diagnose Peripheral Vascular Disease or Peripheral Artery Disease
(PAD), doctors perform peripheral vascular angiography. During this
procedure, a catheter is used to inject dye into the peripheral
arteries. X-rays are then taken of the blood flow inside the arteries to
determine the exact location of the PAD.
To treat arterial blockages resulting from PAD, Lankenau’s
interventional cardiologists use balloon angioplasty and stenting. This
minimally invasive procedure uses a catheter—with a balloon at its
tip—that is fed through the artery to the narrowed area. Doctors then
inflate the balloon to compress the plaque and enlarge the inner
diameter of the blood vessel so that blood can flow more easily. The
balloon is then deflated and a stent is put in place to help keep the
