Ultrasound


 

What is a Ultrasound

Millions of people suffer from the discomfort and appearance of unsightly varicose and spider veins.  However, many don’t know the causes, symptoms and treatment options available to them.  Varicose veins are often the result of an underlying vascular condition called venous reflux.  This occurs when the valves in the leg veins don’t function properly, and it is not just a cosmetic problem. 

  • A transducer, a small, microphone-like device, will be placed over various locations on your leg(s).
  • Sound waves will bounce off the muscle and tissue in your body and off the blood moving in your arteries. This creates "echoes." The echoes are reflected back to the transducer. A television monitor shows images as the transducer converts the echoes to electronic signals.


Ultrasound is a procedure that uses sound waves to "see" inside your body. An arterial duplex ultrasound uses sound waves to create a color map of the arteries in your leg(s) to identify narrowing of your vessels that may be causing leg pain when walking, resting leg pain, foot, ankle, heel or toe ulcers, or skin discoloration

During Your Exam

  • The  Registered Vascular Specialist (RVS) will explain your exam and answer any questions you may have.
  • Your procedure will be performed with you lying on the examination table on your back with your hands at your sides or on your stomach.

  • The RVS will apply  gel to your leg(s).
  • You will hear unusual sounds as the RVS views and records the blood flowing through the veins and arteries in your leg(s).
  • Blood pressure readings will be taken of your ankles. You will not feel any pain; however you will feel mild pressure from the blood-pressure cuff and the transducer.

What is a Carotid Doppler Ultrasound Exam? 

A carotid Doppler ultrasound is a diagnostic test used to check the circulation in the large arteries in the neck. This exam shows any blockage in the artery by a blood clot or “thrombus” formation. Any blockage of these arteries can result in brain damage or strokes.

Over time, plaque can harden or rupture (break open). Hardened plaque narrows the carotid arteries and reduces the flow of oxygen-rich blood to the brain.

Signs and Symptoms of DVT

Prolonged sitting and or standing should be avoided. If you have a standing profession or if you find yourself standing for an extended amount of time, shift your weight from leg to leg or wear compression hose. When sitting for more than 30 minutes, try to elevate the legs above heart level. If that is not possible, stand up and walk around for a few minutes before sitting again. Also, consider the use of compression hose.

Half of all DVT cases cause no symptoms. If you do have any of the DVT symptoms below -- especially if they occur suddenly -- call your doctor right away

Figure A shows the location of the right carotid artery in the head and neck. Figure B is a cross-section of a normal carotid artery that has normal blood flow. Figure C shows a carotid artery that has plaque buildup and reduced blood flow.
