Using an open incision or a percutaneous (small incision in the skin) approach, the provider places a balloon–tipped catheter into the lumen (interior) of a vein (except for the dialysis circuit) and expands the balloon as many times and at as many points as necessary within the same vein to open up the vein and improve blood circulation. The procedure includes all imaging guidance and diagnostic imaging necessary to carry out the angioplasty and all radiological supervision and interpretation (RS&I).
