New Guideline for treatment of DVT and PE – ACCP 2016

The ACCP Chest Guidelines have been the main guide over the last more than 2 decades for evidence-based recommendations on best management of blood thinners for various indications, including DVT and PE.  The 10th edition of the chapter on DVT and PE management was published in Jan 2016 [reference]. Unfortunately, the guideline is not available for non-subscribers.

30 Recommendations

This 38 page document focusses on the best management of DVT and PE.  It provides 30 individual recommendations (page 7-19) and a discussion of the evidence behind the guidance.  It uses the terms “suggest” and “recommend” for its guidance, depending on the strength of published evidence.

Key Recommendations

  • Choice of blood thinner:
    In patients with DVT of the leg or PE (and no cancer) the suggestion is to use one of the newer oral blood thinners (Eliquis, Pradaxa, Savaysa or Xarelto) rather than warfarin (Coumadin, Jantoven) therapy!
  • Cancer patients with DVT or PE:
    In cancer patients with DVT of the leg or PE an injectable blood thinner called “low molecular weight heparin” (Lovenox = enoxaparin; Fragmin = dalteparin; Innohep = tinzaparin) is suggested rather than an oral drug.
  • How long to treat with blood thinners?
    • DVT (in veins in the pelvis, thigh or behind the knee, termed “proximal DVT) or PE provoked by surgery:  recommend 3 months of blood thinners.
    • Proximal DVT or PE  provoked by non-surgical transient risk factor (e.g. estrogens, pregnancy, leg injury, flight > 8 hrs): suggest 3 months of blood thinners.
    • Unprovoked proximal DVT or PE: suggest long-term blood thinners.
    • Distal DVT, i.e. below the knee
      • if not severely  symptomatic : suggest no blood thinners, but follow-up Doppler ultrasound imaging study
      • if severely symptomatic: suggest 3 months of blood thinners.
  • Role of aspirin:
    In patients with unprovoked proximal DVT or PE who stop blood thinners, aspirin is suggested.

Personal comment

This is a solid guideline and good publication.
