From the Guidelines
The management of a patient with a positive Homan's sign suggesting deep vein thrombosis (DVT) requires prompt anticoagulation therapy with a direct oral anticoagulant (DOAC) such as apixaban or rivaroxaban, as these have been shown to be more effective and safer than traditional anticoagulants like warfarin 1. Initial management includes starting apixaban (10 mg twice daily for 7 days, then 5 mg twice daily) or rivaroxaban (15 mg twice daily for 21 days, then 20 mg once daily). Anticoagulation therapy typically continues for 3-6 months depending on whether the DVT was provoked or unprovoked. Some key points to consider in the management of DVT include:
- The use of low molecular weight heparin (LMWH) or unfractionated heparin may be considered in certain situations, but DOACs are generally preferred due to their ease of use and reduced risk of bleeding complications 1.
- Supportive measures include leg elevation, compression stockings (30-40 mmHg) once acute symptoms improve, and early ambulation.
- Patients should be educated about medication adherence, bleeding risk signs, and the importance of follow-up appointments.
- Compression stockings should be used routinely to prevent postthrombotic syndrome, beginning within 1 month of diagnosis of proximal DVT and continuing for a minimum of 1 year after diagnosis 1. This aggressive management approach is necessary because untreated DVT can lead to serious complications including pulmonary embolism, post-thrombotic syndrome, and chronic venous insufficiency 1.

Management Plan for Deep Vein Thrombosis (DVT)
The management plan for a patient with a positive Homan's sign indicating DVT involves several key components:
- Anticoagulation therapy: The standard treatment for DVT, which reduces the risk of pulmonary embolism and recurrence of DVT 2, 3, 4, 5.
- Initial treatment: Options include low-molecular-weight heparin (e.g., enoxaparin), unfractionated heparin, or fondaparinux, with the goal of preventing further clot formation 3.
- Long-term treatment: Oral anticoagulants such as rivaroxaban, which has been shown to be effective and safe for the treatment of VTE 4, 5.
- Risk stratification: Patients with DVT should be risk-stratified to guide clinical management, including the use of anticoagulation therapy and the duration of treatment 5.
- Compression therapy: Used to prevent postthrombotic syndrome, a common complication of DVT 5.
- Thrombolytic therapy: May be considered in select patients with DVT, but is limited by contraindications and potential risks 6.
Treatment Options
Some specific treatment options for DVT include:
- Rivaroxaban: An oral direct factor Xa inhibitor that has been shown to be effective and safe for the treatment of VTE 4, 5.
- Enoxaparin: A low-molecular-weight heparin that is commonly used for the initial treatment of DVT 2, 3.
- Fondaparinux: A synthetic pentasaccharide that has been shown to be effective and safe for the initial treatment of DVT 3.
- Heparinization: The use of unfractionated heparin or low-molecular-weight heparin to prevent further clot formation 2.
