The word vascular refers to the circulatory system of the body— the blood vessels which carry oxygenated blood from the heart to the body's organs (by the arteries) and from the organs back to the heart (by the veins). This type of ultrasound is called Duplex Ultrasound.
The vascular
system is the main transportation mechanism of the body. The arterial system
delivers oxygen and nutrients to the organs to help them replace dead tissues
and grow and the venous system is responsible for the removal of waste products
from cells. Owing to genetic factors and the Western lifestyle, the function of
the vascular system is seriously at risk here.
A computer
converts the sound waves into two-dimensional, black and white moving pictures
called B-mode images to analyse and assess if the conventional blood flow is
affected by any problem in the blood vessels, such as cholesterol deposits, if
there is any other types of blockage in the vessels or if the speed of blood
flow is affected due to any blockage.
Why It Is Done
The vascular
technology utilizes diagnostic ultrasound to generate images of blood flow
within the veins and arteries using high frequency sound waves to make sure
that the circulatory system in our body is functioning well. For example, if
your physician wants to make sure that you do not have a blood clot in your
leg, he or she might order a vascular ultrasound for that part of the body.
The
information obtained through vascular ultrasound examinations is extremely
helpful to physicians in diagnosing a variety of conditions related to
cardiovascular disease, disorders of the heart and blood vessels. Early
detection of life-threatening vascular diseases is possible through the use of
non-invasive vascular testing techniques performed within vascular facilities.
Your physician may recommend a duplex ultrasound to
help diagnose and examine conditions that affect the blood vessels. These
conditions include:
Risks
Vascular
ultrasound procedures are non-invasive, meaning they do not require the use of
needles, dyes, radiation or anaesthesia and are, therefore, relatively painless
and harmless.
