How we diagnose and treat deep vein thrombosis
Key result
Diagnosis of deep vein thrombosis requires clinical assessment and objective testing, followed by initial therapy with low-molecular-weight heparin and long-term oral anticoagulants.

Implication
Supports established DVT diagnostic algorithms and LMWH-to-oral anticoagulation; leaves open benefits of newer agents in trials.
Key Points
- To evaluate the accurate diagnosis and effective treatment strategies for deep vein thrombosis.
- Patients stratified into risk categories using a validated clinical model.
- Diagnosis confirmed via venous ultrasound or negated with D-dimer test in low-risk patients.
- Treatment initiated with low-molecular-weight heparin followed by oral anticoagulants.
- Acute symptomatic DVT confirmed with positive ultrasound in intermediate/high-risk patients.
- DVT ruled out in low-risk patients with normal ultrasound and negative D-dimer.
- New anticoagulants are being tested for potential advantages over existing treatments.
