Do you utilize D-dimer to inform anticoagulation duration in the treatment of VTE?

Provoked or unprovoked VTE: Do you use D-Dimer (or even repeat imaging to reassess residual clot) in any capacity to guide anticoagulation duration?

While not recommended in guidelines, do you think these tests have any role when the provider or patient is on the fence regarding duration of re-addition of anticoagulation.

I find that most patients now opt to continue anticoagulation given the ease of doac us...

I tend to use D-dimer more often than is recommended in guidelines. My late mentor, Dr. Neil Lachant, referred to D-dimer testing to guide anticoagulation as a "lost art."

Here are situations in which I will use it:

I will utilize it for superficial venous thrombosis (refer to the excellent algori...

I hope that my message is clear that the combination of d-dimer, factor VIII synergism is key as well as consideration regarding residual venous changes, damaged valves, lack of complete clot resolution, fibrin changes in the vein, etc. This is a complex algorithm that was very successful for me but...
