Treatment of Proximal Lower Limb DVT — Thrombus in the Popliteal, Femoral, or Iliac Veins

Proximal deep vein thrombosis (DVT) is defined by thrombus in the popliteal, femoral, or iliac veins. This anatomical distribution places it in a distinct clinical category requiring a specific, guideline-directed treatment approach.

Clinical Scenario

Proximal DVT is defined as thrombus in the popliteal, femoral, or iliac veins. This location distinguishes it from distal (calf-confined) DVT and determines the treatment strategy outlined in this protocol.

Treatment Approach (Partial Overview)

Anticoagulation therapy is the cornerstone of management, with certain oral anticoagulant agents recommended as the preferred approach in eligible patients — the full regimen, agent selection criteria, and additional considerations are detailed in the complete protocol.

The 2021 CHEST guidelines recommend treating proximal DVT with anticoagulation for at least 3 months.
The 2021 CHEST guidelines recommend the use of DOACs over warfarin whenever possible, based on data showing a lower risk of major bleeding (especially intracranial hemorrhage) with DOACs vs warfarin (strong recommendation with moderate-certainty evidence).
