From the Guidelines
The treatment of arm deep vein thrombosis (DVT) typically involves anticoagulation therapy, with a minimum duration of 3 months, as suggested by the most recent guidelines 1. The diagnostic workup includes a thorough history and physical examination, followed by imaging with compression ultrasonography as the first-line test. If ultrasound is inconclusive, MR venography or CT venography may be used. Laboratory tests should include a complete blood count, coagulation studies, and consideration of thrombophilia testing in younger patients or those with recurrent or unprovoked thrombosis. Some key points to consider in the treatment of arm DVT include:
- Anticoagulant therapy alone is recommended over thrombolysis for patients with acute upper extremity DVT that involves the axillary or more proximal veins 1.
- The same intensity and duration of anticoagulant therapy is recommended for patients with upper extremity DVT who undergo thrombolysis as for those who do not undergo thrombolysis 1.
- For cases involving central venous catheters, anticoagulation without catheter removal is the preferred option for initial treatment, provided that the catheter is necessary, functional, and free of infection 1.
- The recommended duration of anticoagulation depends on tolerance of anticoagulation, response to anticoagulation, and catheter status, with consideration of longer duration anticoagulation in patients with catheters with poor flow, persistent symptoms, or unresolved thrombus 1.
- Direct oral anticoagulants (DOACs) like rivaroxaban, apixaban, or edoxaban are preferred over warfarin due to their predictable dosing and fewer monitoring requirements 1.
- Thrombolysis may be considered in severe cases with extensive clot burden, particularly in younger patients with low bleeding risk 1.
- Surgical decompression may be necessary after initial anticoagulation for cases involving thoracic outlet syndrome or effort thrombosis (Paget-Schroetter syndrome) 1.

The provided drug labels do not directly address the treatment and workup for deep vein thrombosis (DVT) of the arm. The FDA drug label does not answer the question.
From the Research
Treatment of Arm DVT
- The mainstay of treatment for deep vein thrombosis (DVT), including arm DVT, is anticoagulation 2.
- Most patients with DVT can be treated in the outpatient setting with low-molecular-weight heparin and a vitamin K antagonist (warfarin) or direct-acting oral anticoagulants 2.
- Inpatient treatment of DVT begins with parenteral agents, preferably low-molecular-weight heparin, and unfractionated heparin is used if a patient is hemodynamically unstable or has severe renal insufficiency, high bleeding risk, hemodynamic instability, or morbid obesity 2.
Workup for Arm DVT
- The workup for arm DVT typically involves diagnostic imaging, such as ultrasound or venography, to confirm the presence of a blood clot in the deep veins of the arm.
- Patients with arm DVT should be evaluated for underlying risk factors, such as cancer, trauma, or thrombophilic conditions 3.
- The location and extent of the clot, as well as the patient's overall health and medical history, will guide treatment decisions 2.
Anticoagulation Therapy
- Low-molecular-weight heparin (LMWH) is at least as effective and safe as unfractionated heparin for the treatment of DVT 4, 3, 5.
- Direct-acting oral anticoagulants, such as rivaroxaban, are also effective and safe for the treatment of DVT, with the advantage of predictable anticoagulant effect and no need for periodic monitoring 6.
- The optimal duration of anticoagulant therapy after DVT is still debated, but current guidelines recommend anticoagulation for a minimum of three months 2.
