11 – Does the administration of VTE prophylaxis to patients undergoing orthopedic procedures increase the rate of post-operative non-VTE complications?

Jean-Yves Jenny.

Response/Recommendation: Administration of pharmacological venous thromboembolism (VTE) prophylaxis to patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA) increases the rate of post-operative bleeding complications. Potent anticoagulants may be more at risk than aspirin (ASA). The literature is inconclusive for other orthopaedic procedures.

Strength of Recommendation: Strong.

Rationale: Although compressive stockings and fast-track rehabilitation are effective in reducing the incidence of VTE1, routine pharmacological VTE prophylaxis is generally recommended2. Current recommendations provide a list of procedures requiring VTE prophylaxis, focusing on THA or TKA and proximal hip fracture2,3. However, there is a general trend to extend the pharmacological VTE prophylaxis to other procedures based on perceived level of risk4. Commonly used agents include: Low-molecular-weight heparin (LMWH), fondaparinux, direct oral anticoagulant (DOAC), low-dose unfractionated heparin, adjusted-dose or low-dose vitamin K antagonist, or ASA2,3.

There is no evidence in the literature that nonpharmacological VTE prophylaxis (mechanical compression, early ambulation, fast-track procedures) increases the risk of post-operative complications5–8.

In contrast, the use of any pharmacological agent involves risk. Some complications such as heparin-induced thrombocytopenia are rare. Excess bleeding is the major risk which can manifest as an increase in wound discharge9. Haematoma formation may require further surgery or allogeneic transfusion10 both of which can increase the rate of surgical site infection11–14.

There is extensive literature for THA and TKA. While the risk of VTE events is currently decreasing, probably because of the more frequent use of fast-track procedures, the risk of bleeding remains unchanged7. The risk for bleeding without VTE prophylaxis remains difficult to estimate because modified operative and recovery techniques may make the untreated bleeding event rate deriving from the placebo group of past studies2. There are only few recent studies including a control group without pharmacological VTE prophylaxis15–17. The increased bleeding risk18,19 may not be compensated for by the administration of tranexamic acid18. However, the routine use of tranexamic acid and more restrictive transfusion policy has dramatically decreased the need for transfusion after primary THA and TKA20, and the impact of VTE prophylaxis may be difficult to assess.

The risk may be further increased when potent anticoagulants drugs are administered in comparison to ASA21–23, but some authors report conflicting results24, and the rates may be different for THA and TKA6. There is little evidence that different potent anticoagulants agents other than ASA are associated with different risks of bleeding25,26.

Early readmission and repeat surgery rates after primary THA or TKA are affected by the occurrence of bleeding and wound discharge27. As bleeding and wound discharge are more frequent with pharmacological VTE prophylaxis, readmission and further surgery rates may be higher as well.

There is a paucity of recent literature for other orthopaedic procedures than THA and TKA, and no scientifically supported conclusion can be suggested.
