Thrombosis and haemostasis

What we do

Our service leads the UK in the diagnosis, treatment and prevention of venous thromboembolism (VTE).

We diagnose and treat conditions including:

  • venous thrombosis such as deep vein thrombosis (DVT) and pulmonary embolism (PE)
  • thrombophilias including genetic thrombophilia and acquired conditions such as antiphospholipid syndrome (APS)
  • thrombocytosis, thrombocytopaenia and polycythaemia.
  • suspected bleeding disorders.

We offer fast assessment of patients with suspected DVTs, usually seeing them the day they are referred. We aim to make a diagnosis within two hours and have patients needing treatment home within four hours.

As part of our high-quality, patient-centred service, we have an extensive research programme. Current projects include:

  • improving outcomes after DVT
  • examining how thrombophilia (a condition where blood clots too easily) affects miscarriage
  • learning the lessons from thrombosis brought on by hospital stays.

Conditions we treat

Our service has various clinics covering the following conditions:

  • thrombophilia
  • antiphospholipid syndrome (APS)
  • thrombocytosis
  • thrombocytopaenia
  • polycythaemia
  • suspected bleeding disorders.

Our DVT service has become a template for innovation and good practice. Patients are referred for rapid assessment of suspected DVT and are usually seen on the day of referral in a nurse-led clinic. They are anticoagulated and undergo in-house individualised risk factor assessment, thrombophilia testing and cancer screening. Time to diagnosis is now under two hours and patients requiring treatment are home within four hours. We also operate an early-discharge PE service.

King’s Thrombosis Centre carries out extensive translational research to ensure it continues delivering a high-quality patient-centred service. Current projects include:

  • defining and improving outcomes after DVT
  • characterising the prothrombotic state in obesity
  • optimising low molecular weight heparin regimens in pregnancy
  • defining the role of thrombophilia in pregnancy loss
  • characterising the prothrombotic state after stroke
  • examining haemostatic abnormalities in liver disease
  • learning the lessons from hospital-associated thrombosis.
