General Medicine · Haematology: deep vein thrombosis duration

Sample item

A patient develops a calf DVT after a long flight (provoked by a transient risk factor). How long should a DOAC be given?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Three months

Provoked DVT due to a major transient risk factor is treated for 3 months, since the risk of recurrence after stopping is low. Unprovoked events need extended therapy based on bleeding risk. Cancer-associated thrombosis is treated for at least 6 months.

Option by option

  • A. One week

    One week is inadequate and risks recurrence.

  • B. Lifelong

    Lifelong therapy is for recurrent or persistent risk.

  • C. Two years

    Two years is not needed.

  • D. Three months (correct)

    Correct. Three months suffices for provoked DVT.
