Case 66 – update 3

Our patient is diagnosed with essential thrombocythaemia/thrombocytosis (JAK2 V617F positive) and is started on aspirin 75mg od.


At 28 weeks she has a painful swollen left leg. It is hot and tender. An ultrasound confirms a deep vein thrombosis.



  • Why do most DVTs occur on the left side?
  • What would you treat with and what dose?
  • Would you monitor anti-Xa activity?
