![]() Post-thrombotic syndrome may occur with symptoms of chronic pain, swelling, skin discoloration, or venous ulcers following chronic obstruction of venous outflow and/or incompetence of venous valves. Thereafter, continued anticoagulant therapy for secondary prevention is indicated in selected patients to reduce the risk of recurrent events. Generally, anticoagulant therapy for at least 3 months is required for patients with DVT. Interventional therapies, including thrombolysis, are rarely indicated. DVT may also be unprovoked (idiopathic) and occur in the absence of any identifiable extrinsic risk factors.ĭVTs commonly cause asymmetrical leg swelling, unilateral leg pain, dilation or distension of superficial veins, and red or discolored skin, but can also be asymptomatic.Īssessment of pretest probability (using a validated score such as Wells score) is key if DVT is suspected, and should be used in combination with an algorithmic diagnostic approach to avoid unnecessary imaging when the likelihood of DVT is low.ĭiagnosis requires confirmation of a blood clot in a deep vein in the leg, pelvis, or vena cava by venous duplex ultrasound imaging or computed tomography scan.ĭVT is usually treated with anticoagulants such as unfractionated heparin, low molecular weight heparin, fondaparinux, rivaroxaban, apixaban, edoxaban, dabigatran, and/or warfarin. Patients who develop DVT commonly have risk factors, such as cancer, trauma, major surgery, hospitalization, immobilization, pregnancy, or oral contraceptive use. DVT most commonly affects the legs, but can also affect the arms, and other sites in the body. The doctors will review you and decide if you will benefit from anticoagulant medication to thin the blood and reduce clotting.Deep vein thrombosis (DVT) is the development of a blood clot within a vein deep to the muscular tissue planes. What if my test shows I have a blood clot? A deep vein thrombosis can break loose and cause a serious problem in the lung. If the vein swells, the condition is called thrombophlebitis. Most deep vein clots occur in the lower leg or thigh. Download figure Download PowerPoint Figure 1. ![]() ![]() Deep vein thrombosis, or dvt, is a blood clot that forms in a vein deep in the body. Lower-extremity venous duplex ultrasound (VDUS) with B-mode compression maneuvers and Doppler evaluation was performed, and she was found to have an acute deep venous thrombosis (DVT) of the left leg that extended from the common iliac vein into the left calf ( Figure 1A1E ). The results of your scan will be sent back to your doctor, or if you have been referred from A&E we will give you your report to take back to the doctors there immediately after. A blood clot (thrombus) in a deep vein in the lower extremity. The flow in your veins will be examined, which usually requires some gentle squeezing of the calf, and the veins will be compressed to make sure they are not obstructed by clot, which involves some gentle pressure with the ultrasound probe. On visiting the vascular lab for a DVT assessment, we will use an ultrasound scanner with some cool gel to visualise the veins in the affected limb or limbs. Why does DVT occur?ĭVT can occur if the limb or vein affected has been involved in trauma or injury, if the limb has been immobile for a prolonged period of time (for example during bed rest or long haul flight), or if the mechanisms for normal blood clotting are for some reason altered (eg. DVT is the partial or total blockage of one or several veins in a limb by clotting of the blood, which can lead to symptoms described above. If you have symptoms such as swelling, tenderness and pain of one or both legs (or less commonly arms), your doctor may send you to the vascular lab for an ultrasound to test for DVT (Deep Vein Thrombosis). ![]()
