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.

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.

Patient information

We have an information booklet for patients taking oral vitamin K antagonists (e.g. Warfarin).

Please ask for a copy when you start your anticoagulant therapy.

Important information for patients on anticoagulation with vitamin K antagonists (pdf)

We also have leaflet for patients who:

  • are referred to the DVT Clinic
  • have been diagnosed with a DVT
  • have a thrombus (clot)
  • need Vitamin K (Phytomenadione)
  • have a leg in a certain position because of a plaster cast or appliance and are in danger of developing a clot.

Please see our 'Patient leaflets' page for the full A-Z of our patient leaflets

Infected blood payment scheme reforms

The payment schemes are for individuals who were infected with HIV and or hepatitis C following treatment with NHS-supplied blood or blood products before September 1991.

As of November 2016, these new annual payments are being processed, and we encourage you to make contact with your fund provider.

Oxford Haemophilia and Thrombosis Centre is very active in clinical research, participating in many national and international studies.

If you have haemophilia, or other rare conditions, you are very likely to be asked to consider taking part in a study to help improve future treatment. This could range from answering a few questions and/or a single blood test, through to trialling a new treatment over a number of years.

The choice to take part in research is entirely yours. If you prefer not to take part, your decision will be respected by your team and it will not affect the care you receive.

Research areas include:

  • novel non-factor haemophilia treatment
  • selection of viruses for gene therapy in haemophilia
  • long-acting factor treatments
  • joint disease in haemophilia
  • genetics of rare bleeding conditions
  • use of novel oral anticoagulants in cancer patients
  • long-term treatment outcomes of patients with DVT and/or PE.
