The American Academy of Family Physicians (AAFP)/American College of Physicians (ACP) recommendations for workup of patients with probable DVT are as follows [5] :

  • Validated clinical prediction rules (eg, Wells) should be used to estimate the pretest probability of VTE and interpret test results

  • In appropriately selected patients with low pretest probability of DVT or PE, it is reasonable to obtain a high-sensitivity D-dimer

  • In patients with intermediate to high pretest probability of lower-extremity DVT, ultrasonography is recommended

  • In patients with intermediate or high pretest probability of PE, diagnostic imaging studies (eg, ventilation-perfusion scan, multidetector helical CT, and pulmonary angiography) are required
