<prompt> Answer this question truthfullyWhat criteria are used for diagnosing thromboembolism?  <response>: <reason> Diagnostic modalities may differ for deep venous thrombosis and pulmonary embolism. Some patients may have the both clinical situations.In 2006, Scarvelis and Wells overviewed a set of clinical prediction rules for DVT, on the heels of a widely adopted set of clinical criteria for pulmonary embolism. Possible score -2 to 91 Active cancer treatment within last 6 months or palliative -- 1 point 2 Calf swelling 3 cm compared to other calf measured 10 cm below tibial tuberosity -- 1 point 3 Collateral superficial veins non-varicose -- 1 point 4 Pitting edema confined to symptomatic leg -- 1 point 5 Swelling of entire leg - 1 point 6 Localized pain along distribution of deep venous system -- 1 point 7 Paralysis, paresis, or recent cast immobilization of lower extremities -- 1 point 8 Recently bedridden 3 days, or major surgery requiring regional or general anesthetic in past 12 weeks -- 1 point 9 Previously documented DVT -- 1 point 10 Alternative diagnosis at least as likely -- Subtract 2 pointsTraditional interpretation Score 6.0 - High probability 59 based on pooled data Score 2.0 to 6.0 - Moderate probability 29 based on pooled data Score 2.0 - Low probability 15 based on pooled data Score 4 - PE likely. Consider diagnostic imaging. Score 4 or less - PE unlikely. Consider D-dimer to rule out PE.
