This painless test uses ultrasound to create a "map" of the veins, typically in the leg. This might be done in preparation for various procedures, like bypass graft surgery (replacing diseased vessels in the body with a healthy vein from the leg).
In balloon angioplasty, a catheter with a small balloon on its tip is inserted into the blockage site. Once there, the balloon is inflated in the artery to flatten or compress the plaque against the artery wall.
This is used to treat aneurysms using a minimally invasive approach. In the procedure, the doctor threads a stent (small mesh tube) through a catheter inside of the aneurysm so that blood flows in the proper direction.
