Deep Vein Thrombosis (DVT)

The DVT service is a 'one-stop diagnostic shop' for adult patients with suspected DVT. GPs can refer patients directly to the service for assessment. The service has its own laboratory and ultrasound room to speed up diagnosis. If a patient does have a DVT, they can discuss treatment options and start treatment the same day.

  • Monday to Friday 9.00am - 5.00pm
  • Weekends and Bank Holidays: reduced service 9.00am - 1.00pm

Outside these hours GPs should decide whether the patient is suitable for outpatient assessment and treatment.

If they are not suitable, the patient should be referred to the on-call medical team at the John Radcliffe Hospital. If they are suitable for outpatient assessment and treatment, a dose of either Low Molecular Weight Heparin (LMWH), apixaban or rivaroxaban should be given and an appointment arranged for the DVT Clinic the following day.

Please note that edoxaban and dabigatran are not licensed for acute treatment of VTE.

To arrange this appointment please telephone 01865 225629 and leave a full voicemail with the patient's details and a contact telephone number, or email these details to:

Thromboprophylaxis Service

The Thromboprophylaxis Service works to prevent clots, both deep vein thrombosis and pulmonary embolism. We mostly treat inpatients, but where extended thromboprophylaxis is required patients are discharged from hospital with LMWH or another anticoagulant.

This could be after a hip or knee arthroplasty, and major abdominal or pelvic surgery for a malignancy. For patients with lower limb immobilisation, such as plaster casts or non-weight bearing braces, extended prophylaxis should be considered.
