Venous thromboembolism is a frequent disease with an annual incidence of 0.75-2.69/1000 reaching 2-7/1000 > 70 years. Deep vein thrombosis (DVT) and pulmonary embolism are two manifestations of the same underlying disease. Most frequent localization of DVT is at lower limbs. The diagnostic workup begins with an estimation of DVT risk, a judicious use of D-Dimers, and compression venous ultrasound depending on DVT probability. The development of direct oral anticoagulants and recent data on interventional DVT treatment, in selected cases, have widened the therapeutic spectrum of DVT. The present article aims at informing the primary care physician of the optimized workup of patients with lower limb suspicion of DVT.
