Why are vascular studies performed?

Vascular studies are a noninvasive (the skin is not pierced) procedure used to assess the blood flow in arteries and veins. Reasons for which vascular studies may be performed include, but are not limited to, the following:
  • evaluation of signs and symptoms which may suggest decreased blood flow in the arteries and/or veins of the neck, legs, or arms
  • evaluation of previous procedures that were performed to restore blood flow to an area
  • evaluation of a vascular dialysis device, such as an A-V fistula in the arm
There may be other reasons for your physician to recommend a vascular study.
