Vascular Doppler Ultrasound

Vascular Doppler ultrasound allows physicians to look at the veins so that they have a better idea of which vessels will work best for dialysis treatment. When you suffer from kidney diseases, you are at risk of several infections. The kidneys are necessary for cleaning the blood. Sometimes drinking too much alcohol and poor eating Vascular Doppler Ultrasound md top10md habits leads to a decrease in kidney function. There are times where the kidneys stop functioning completely. Whenever the kidneys are not doing their job, dialysis is necessary. There are a lot of things that needs to happen in the background before you start dialysis. Vascular Doppler Ultrasound is one of the necessary things that must happen before dialysis can begin.

Kidney Function

The primary function of the kidneys is to filter the blood and balance fluids in the body. Kidneys can be damaged by certain medications as well as infections. When infections get into the blood, they may damage the kidneys. Sometimes alcohol will also cause damage as well. When the kidneys have to filter out alcohol continuously, it destroys kidney function. The kidneys cannot function at all without arteries. The renal artery supplies the kidneys. If there is a problem with the renal artery, the kidneys will begin to fail. Atherosclerosis is a major issue for the kidneys. Cholesterol builds up in the arteries, and blood flow subsequently becomes limited. Blood pressure is affected, and health begins to fade.

When the kidneys are no longer doing their job, dialysis does it for them. Dialysis both filters and purifies the blood. Dialysis can remove waste, additional substances, and impurities. The two types of dialysis include hemodialysis and peritoneal dialysis. They work in two different methods to produce the same results. When you undergo hemodialysis, the first step is a vascular ultrasound. The vascular ultrasound shows the health of the veins and arteries throughout the body.

Vascular Doppler Ultrasound

A vascular Doppler ultrasound uses sound waves to produce an image. If you have been pregnant before, you know how an ultrasound works. The doctor uses a probe that projects an image on a computer screen. When analyzing the blood vessels for dialysis, the technician will look at the vessels in the arm, neck, abdomen, and legs. Ultrasound is effective because it does not require the use of dye and it is non-invasive. Thre are no incisions, and there is no need for anesthesia. The physician can also see if there is a vascular disease related to kidney dysfunction. When the probe is put on the tissues, sound waves are transmitted. When the sound waves reach the blood vessels, they are reflected off the blood cells, and the wave returns to the ultrasound machine. The image is transmitted to the computer where the technician can evaluate them. Vascular speed is one thing that is measured. Through an ultrasound, the speed of blood flow can be measured. When blood moves too fast in the blood vessel, it means there is a blockage in the vessel. When trying to find the right vein for dialysis, that vein will not work. Blood pressure and oxygen levels are also analyzed.


There are several benefits to ultrasounds. Other methods will allow the doctor to see blood vessels, but ultrasound is the most effective. CAT scans and MRI scans show the blood vessels, but it may not give a good enough look at the vessels. You also cannot be moved around during a CAT scan and MRI scan. Both MRIs and CAT scans expose you to radiation. There is no radiation exposure with ultrasound. There is no need for the use of dye either. Another benefit of using ultrasound is that it does not cause any pain and does not require recovery time.  Once the results are in, a doctor can analyze it and decide on the next step.

The purpose of vascular Doppler ultrasound is to find the right vein for dialysis. If dialysis is done and the wrong vein is used, it will not work. There are certain criteria for what vein can be used. The vein has to be the right size and has to be healthy. Once the right vein is found, the doctor will create an entry point where the hemodialysis will take place. Sometimes that means creating an arteriovenous fistula; this requires the connection between the vein and the arteries. Once the vascular entry point is made, the physician can start dialysis.

Vascular Doppler Ultrasound is a great way for a physician to analyze the blood vessels. If you are in need of dialysis, vascular doppler ultrasound allows the doctor to see if hemodialysis will work. There are times when the veins are not good enough to deal with hemodialysis. If that is the case, peritoneal dialysis will have to do. If you need a vascular ultrasound, you do not have to be afraid. It is a painless procedure used for the purpose of analysis.
