How to Detect Dvt

DVT, or deep vein thrombosis, refers to blood clot formation in a deep vein, usually in the calf or thigh. You may be at risk for DVT if you have surgery, especially if the procedure is on your lower extremities. Factors that may contribute to DVT are advancing age, smoking, obesity, prior history of DVT, estrogen use, current pregnancy, and genetic factors. If you suspect you have a DVT, you need diagnosis and treatment, or you may risk a pulmonary embolism. Pulmonary embolism occurs when a blood clot breaks free and travels to the lungs. There are steps you can take to detect DVT.

Instructions

• 1

  See your doctor. You will need a physical examination so your doctor can inspect your legs for signs of DVT. He will look for swelling in your calf, pain, redness, warmth over the area and distended or swollen veins. Your treatment will depend on the findings of your examination.

• 2

  Get a venogram. According to the website, Orthoinfo.aaos.org, venography uses radiographic dye that is inserted into the vein on top of the foot. The dye combines with blood, and flows in the direction of the heart. An x-ray will image the veins to see if you have blockages that indicate a DVT.

• 3

  Ask about duplex ultrasonography. Ultrasound studies use sound waves to create images that may reveal a blood clot or DVT.

• 4

  Inquire about MRI. An MRI may detect a DVT in the pelvic area, thigh, or calf. If you are claustrophobic, MRI may not be suitable for you because it involves lying still in a tubelike machine. Discuss the MRI procedure with your doctor. If you are anxious before the procedure, you will be given a mild anti-anxiety medication to calm you.

• 5

  Get blood tests. Blood tests may reveal a blood clotting disorder. Blood tests in conjunction with your symptoms may assist your doctor in detecting a DVT.
