Is it different than early mobility that we always encourage?

I.e. platelet count <30. Would your management change if HIT were only suspected rather than confirmed?  

What is the work up and what is the duration of anticoagulation if used?

Specifically, asymptomatic subsegmental PE diagnosed within a month from planned bilateral mastectomy for breast cancer. 

Significant history of autoimmune diseases and DVT in family, recent PE/DVT for a month

Is patch or gel HRT with ASA prophylaxis a reasonable option after counseling? Or do you add a prophylactic DOAC? 

Would you consider low dose indefinite anticoagulation in any scenario? Any difference in approach between hematological malignancy and solid tum...

Should we stop checking factor VIII levels as part of thrombosis workup?

FVL heterozygotes are often treated similarly to the general population. Aside from avoiding other VTE risk factors, are there situations where prophy...

How does cirrhosis and/or underlying thrombophilia affect your decision?

For example, for outpatients or resource-limited settings with a moderate probability 4-T score (but low clinical suspicion), would you ever consider ...

e.g. in the setting of using prophylactic heparin in the past but now requiring therapeutic anticoagulation

Would you offer indefinite anticoagulation if the event is unprovoked and the patient has low bleeding risk? 

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

While there are many factors involving:- type (DVT vs PE, unprovoked vs provoked) and severity of venous thromboembolism (VTE) size- duration of antic...

Is there any difference between anticoagulants in this clinical context (e.g. anti-Xa inhibitors vs warfarin vs LMWH)?

Does having a concurrent consumptive process e.g. DIC change your management? 

While thrombophilia testing is not routinely recommended prior to starting OCPs, how about after the development of a VTE?

Ref: EINSTEIN-CHOICE and AMPLIFY-EXT Would you approach this differently in patients with inherited thrombophilias?

Is there a preferred strategy of transfusional support versus reduced-dose anticoagulation during the duration of thrombocytopenia?

Would you offer this routinely or only if specific complications arise, such as distal emboli?

Would it make a difference if the VTE diagnosis occurs during bevacizumab therapy or whether it preceded the cancer diagnosis?
