Physical Therapy Initiation in Patients with Acute DVT
Initial Management of Acute DVT
- The American College of Chest Physicians recommends that patients with acute DVT should receive anticoagulation therapy before initiating physical therapy, with options including low-molecular-weight heparin (LMWH), fondaparinux, intravenous unfractionated heparin (IV UFH), or subcutaneous unfractionated heparin (SC UFH) 1, 2
- For patients treated with vitamin K antagonists (VKA), parenteral anticoagulation should be continued for a minimum of 5 days and until the INR is ≥2.0 for at least 24 hours, as recommended by the American College of Chest Physicians 3
- The American College of Chest Physicians recommends direct oral anticoagulants (DOACs) such as apixaban, dabigatran, edoxaban, or rivaroxaban over VKA for treatment of acute DVT 3
Timing of Physical Therapy and Ambulation
- Early ambulation is suggested over initial bed rest for patients with acute DVT of the leg who are receiving appropriate anticoagulation, according to the American College of Chest Physicians 3, 4
- Home treatment is recommended over hospitalization for patients with acute DVT whose home circumstances are adequate, as suggested by the American College of Chest Physicians 1, 4
Considerations Based on DVT Location
Proximal DVT
- Patients with proximal DVT should receive a minimum of 3 months of anticoagulation therapy, as recommended by the American College of Chest Physicians 3
- Early mobilization with appropriate anticoagulation is preferred over bed rest for patients with proximal DVT, according to the American College of Chest Physicians 3, 4
Isolated Distal DVT
- For patients with isolated distal DVT without severe symptoms or risk factors for extension, serial imaging for 2 weeks is suggested over immediate anticoagulation, as recommended by the American College of Chest Physicians 1, 5
- For patients with isolated distal DVT with severe symptoms or risk factors for extension, anticoagulation is suggested over serial imaging, according to the American College of Chest Physicians 1, 5
Special Considerations
- Compression stockings are no longer routinely recommended to prevent post-thrombotic syndrome (PTS) in patients with acute DVT, as stated by the American College of Chest Physicians 6
- However, compression stockings may still be beneficial for symptomatic relief in patients with acute or chronic symptoms, according to the American College of Chest Physicians 6
- For patients with upper extremity DVT (UEDVT) involving the axillary or more proximal veins, anticoagulant therapy alone is suggested over thrombolysis, as recommended by the American College of Chest Physicians 4
Monitoring During Physical Therapy
- Regular reassessment of bleeding risk is important, especially for patients on extended anticoagulation therapy, as suggested by the American College of Chest Physicians 3
Contraindications to Early Mobilization
- Patients with massive pulmonary embolism with hemodynamic instability should not undergo early mobilization until stabilized, however this is based on a lower quality reference and the American College of Chest Physicians may have a different stance 7
