![]() Surgery may be needed if these other methods do not work, including implanting a vena cava filter in the abdomen area to prevent blood clots from reaching the lungs. An injection of a thrombolysis may be required to dissolve the clot. TreatmentĪccording to the Society of Vascular Surgery anti-coagulants, such as heparin or low molecular weight heparin (LMWH), may be injected to help clots from forming and warfarin will then be taken orally for a period of between three to 12 months, depending on the patient’s reactions to the treatment. This test requires a dye injection into the bloodstream, and there may be some complications such as discomfort and an increased chance of clotting. These tests include: the d-Dimer test (a blood test to determine the likelihood of a DVT in the bloodstream), an ultrasound scan, the taking of blood samples to test for genetic or biochemical tendencies for developing a blood clot, or a venogram, which is considered to be the best way to confirm a DVT. The most common signs of a DVT are a noticeable swelling of the leg, a warmth or a redness in the area surrounding the knee (the calf or the thigh area), and leg pain that seems to worsen when standing or walking.Ī physician may conduct a variety of tests if a DVT is suspected in the knee area. It is not until a DVT occurs above the knee that symptoms will appear, and then it becomes crucial to begin treatment for the clotting. Most will go undetected because they do not cause any obvious swelling or pain. There is a difficulty in diagnosing small blood clots, especially below the knee. Find the fleshy middle portion of the back middle of your knee. Other causes of blood clots on the knee include: prolonged bed rest or long periods of sitting and lying down, leg paralysis any major surgery under general anesthesia (especially involving hips or legs), and trauma to the knee area from a blow or fall. Place your hands around the front of your knee so your fingers are on the back portion of your knee. A four-compartment fasciotomy was performed, reveling an edematous and necrotic gastrocnemius muscle and a 200 ml clot of blood. Age can be a factor, and the chance of developing a blood clot can increase two-fold in each decade for people over the age of 40. The patient had noted some swelling behind the knee for a number of weeks previously, but the swelling disappeared as the calf became swollen. According to the National Library of Medicine a blood clot may form in the knee area for a variety of reasons 1. ![]()
