Our patient has a swollen left leg and an intermediate Wells’ score but a positive d-dimer result. She goes on to have an ultrasound of her lower limb. There is debate on whether to do a full leg ultrasound scan or just proximal (i.e. not image the calf veins). More of that in the summary. If the ultrasound cannot be completed within four hours a dose of anticoagulation should be given.
In our patient an ultrasound of the proximal veins revealed a DVT in the femoral vein (beware – sometimes called the superficial femoral vein!).
She has a full blood count, coagulation screen, U&E, LFT and bone profile performed.
- What will you use to treat the patient’s DVT?
- How would you investigate a potential cause?
