examine a blood vessel graft used for dialysis if it is not working as expected for example, the graft may be narrowed or blocked.An example is using portions of vein from the leg to surgically bypass narrowed heart ( coronary) arteries. map out the veins in the leg or arm so that pieces of vein may be removed and used to bypass a narrowed or blocked blood vessel.Sonography can help locate the exact site of the vein and avoid complications, such as bleeding or damage to a nearby nerve or artery. aid in guiding placement of a needle or catheter into a vein.In people with a common condition called "varicose veins", the valves that normally keep blood flowing back to the heart may be damaged, and venous ultrasound can help identify the damaged valves and abnormal blood flow. determine the cause of long-standing leg swelling.If the blood clot in the leg is found early enough, treatment can be started to prevent it from passing to the lung.Ī venous ultrasound study is also performed to: These clots may break off and pass into the lungs, where they can cause a dangerous condition called pulmonary embolism. This condition is often referred to as deep vein thrombosis or DVT. The most common reason for a venous ultrasound exam is to search for blood clots, especially in the veins of the leg. What are some common uses of the procedure? It allows the doctor to see and evaluate blood flow through arteries and veins in the body. Venous ultrasound provides pictures of the veins throughout the body.Ī Doppler ultrasound study may be part of a venous ultrasound examination.ĭoppler ultrasound is a special ultrasound technique that evaluates movement of materials in the body. The images can also show blood flowing through blood vessels. Because ultrasound captures images in real-time, it can show the structure and movement of the body's internal organs. Ultrasound exams do not use radiation ( x-rays). A computer uses those sound waves to create an image. The probe collects the sounds that bounce back. High-frequency sound waves travel from the probe through the gel into the body. It uses a small probe called a transducer and gel placed directly on the skin. Ultrasound imaging is also called sonography. It produces pictures of the inside of the body using sound waves. Contact our office to set up a consultation and find out how we can properly exam you for venous reflux.Ultrasound imaging is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Louis with proper techniques for several years. The Laser Vein Center has been confidently treating individuals in St. Wright and his team of highly trained professionals understand how to properly identify venous reflux during our examinations. Choosing the Right Team for Your Venous Reflux Examĭr. This technique shows whether blood is flowing forward towards the heart or back to the feet. The ultrasound probe is placed on the leg and directed over the impacted vein to be studied. The Laser Vein Center uses a Doppler ultrasound while our patients stand to properly identify venous reflux. Anything less, such as 30-minute examinations, cannot considered to be an adequate venous reflux exam. A complete bilateral lower extremity venous color duplex ultrasound exam requires approximately one and a half to two hours to be performed. It is essential for physicians to understand how veins function normally in order to formulate a plan for treatment. Ultrasound devices do not evaluate for venous reflux and lead to many patients being undiagnosed. This can be seen as facilities performing ultrasounds that only look for deep vein thrombosis or blood clotting. Other cosmetic offices may not use proper methods for their venous reflux examinations. Over-diagnosis and unnecessary procedures are the result of venous reflux exams that are incorrectly done and lead to higher costs for your treatment. Inaccurate results can be gathered if patients are not tested this way, incorrectly identifying valves that are not activated while lying down. Testing for venous reflux should be done while the patient stands for accurate results. When people stand, their valves should keep blood from flowing backwards away from the heart. Venous reflux is a condition that leads to blood pooling in the legs due to valves not properly working. Here is how venous reflux should be properly examined. Wright and his team use proper techniques to find the presence of this debilitating condition. Many exams are currently available to test for venous reflux, but only a few properly look for this condition. This causes blood to pool in the legs that can lead to swelling and distention. Tiny valves help blood return from the extremities back to the heart by preventing backflow, but will no longer function in individuals diagnosed with venous reflux. Venous reflux is a diagnosed condition that can impact the circulation of blood in the legs and arms.
