Ultrasound BILATERAL LOWER EXTREMITY VENOUS DOPPLER
About Test
This test is used to assess the veins of both of your legs for the possible occurrence of blood clots or venous insufficiency. Doppler ultrasound uses sound waves with a special technique to evaluate the movement of blood through the veins of the legs. The images are displayed on the attached monitor. The presence of blood clots in the legs is called deep venous thrombosis (DVT). These clots can break off and pass into the lungs resulting in a life-threatening condition called pulmonary embolism. Doppler ultrasound enables a doctor to diagnose DVT so that it can be treated and prevent the risks of pulmonary embolism.
Why and when do you need this test?
Your doctor may advise for this test if you have leg swelling or tenderness or if the doctor suspects something on physical examination of the legs. This test is required for the following reasons;
- To look for Blood clots (DVT)
- Blockages to blood flow
- Narrowing of vessels
- Congenital vascular malformations
- To check the valves of the veins (in cases of leg swelling)
- Venous insufficiency
- Look for injury to the veins
- To check the condition of the veins to be used for bypass grafts
- To guide the insertion of a venous catheter or taking a biopsy
- Tumors
Do you need to prepare for the test?
Venous Doppler ultrasound of the legs does not need any special preparation.
- You can eat, drink and take your regular medicines normally.
- Wear loose dressing so the legs can be exposed, or you may be given a hospital gown to change into.
- Keep precious pieces of jewelry, watches, etc., at home.
What can you expect?
- You will be asked to lie down on the bed in the ultrasound room.
- After exposing your legs, the technologist will apply gel to your legs.
- Over the gel, a transducer is kept and moved, which transmits sound waves to make images on the computer
- The procedure may take 25-40 minutes.
- After the procedure, the gel will be removed, and you can return home and start your daily activities.
Are there any risks to this test?
Venous Doppler ultrasound is a pain-free procedure, although you may feel discomfort if the area is tender.
This test does not use X-rays, so it is safe.
What do the test results mean?
The radiologist will send a signed report to your doctor, who will be able to tell you if there is any abnormality seen in the report. The abnormal results may include the following;
- Deep vein thrombosis (DVT)
- Superficial thrombophlebitis
- Problem with the valves of the veins
- Arteriosclerosis
- Thromboangiitis obliterans (inflamed and swollen blood vessel disease)
- Arterio-venous malformation
- Vascular tumors in your legs
