Deep Vein Thrombosis (DVT) Service

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
  • Saturday and Bank Holidays: 9.00am - 1.00pm
  • Sunday: closed

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 72 hour supply of either Low Molecular Weight Heparin (LMWH), apixaban or rivaroxaban should be given and an appointment arranged for the DVT Clinic the next available day.

While dabigatran and edoxaban are licensed for acute treatment of VTE, they both require at least five days parenteral anticoagulation prior to initiation.

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

Christmas Day and New Year's Day closed.

VTE Prevention Service

The Oxford University Hospitals (OUH) VTE prevention team works to prevent venous thromboembolism (VTE).

VTE is a collective name for a deep vein thrombosis or DVT (a blood clot in the leg) or pulmonary embolism or PE (a blood clot in your lung).

The most common reason for a VTE to develop is during or following a hospital admission - up to 60 percent of all VTEs in the UK are associated with hospital admissions, and it is important to provide exemplary VTE prevention measures to reduce the risk of avoidable harm to patients.

At OUH, the VTE Prevention Team works collaboratively with the clinical teams to optimise the safety of all inpatients aged 16 and over.

We mostly treat inpatients, but certain high-risk procedures carry a significant risk of VTE that continues after patients leave hospital, and as such a type of anticoagulant is indicated after these procedures. Duration depends on the indication and the agent used but must be supplied by the hospital.

The VTE Prevention Tam at OUH have been revalidated as a VTE Exemplar Centre for a third consecutive time and awarded with a special commendation in recognition of their outstanding work, having demonstrated exceptional quality, innovation and leadership:
