Overview

Overview

Cleveland Clinic's Thrombosis Center is a multidisciplinary specialty treatment group dedicated to the diagnosis and treatment of hypercoagulable conditions or thrombophilia.

The Thrombosis Center brings together clinicians that specialize in blood clotting disorders. The team includes physicians and nurses from Cardiovascular Medicine (Cardiology and Vascular Medicine), the Cancer Institute (Hematology), Laboratory Medicine, Pediatrics, Genetics, Internal Medicine, Interventional Radiology, Cardiovascular and Vascular Surgery, Cardiovascular Anesthesiology, Interventional Radiology and the Lerner Research Institute.

These individuals possess expertise in either genetic and diagnostic testing, medical management or surgical and interventional or endovascular procedures for patients with the genetic (hereditary) and acquired conditions that the center specializes in.

What We Treat

What We Treat

Cleveland Clinic's Thrombosis Center is dedicated to diagnosing and treating conditions related to thrombosis, often called hypercoagulable conditions, thrombophilia or blood clotting disorders. People with these conditions have an increased risk for developing blood clots in the veins (blood vessels that carry blood to the heart) and less often in the arteries (blood vessels that carry blood away from the heart). A clot inside a blood vessel is also called a thrombus or an embolus. Thrombophilia or hypercoagulable conditions are generally due to several factors but may be genetic (inherited) or acquired (following surgery, trauma, hospitalization, medical disease or even related to medications).

These conditions can be dangerous, especially when they are not identified and treated properly. Blood clots increase the risk for death from a pulmonary embolism, stroke or a heart attack. They can also lead to other complications including severe leg pain and/or swelling, difficulty walking, or even the loss of a limb.

Genetic or Hereditary Conditions

  • Factor V Leiden (the most common known hereditary condition )
  • Prothrombin gene mutation (G20210A)
  • Deficiencies of natural proteins that prevent clotting called anticoagulant proteins - such as antithrombin (formerly antithrombin III), protein C and protein S
  • Abnormal fibrinolytic system, (that which breaks down blood clots after they have formed) including hypoplasminogenia, dysplasminogenia, and elevation in levels of Plasminogen activator inhibitor or PAI-1
  • Elevated levels of factor VIII as well as elevation of factors II, VIIa, IX, XI, and XII
  • Elevated homocysteine levels and the common genetic variant methylene tetrahydrofolate reductase (MTHFR)
  • Elevated levels of fibrinogen
  • Elevated levels of lipoprotein (a), a type of cholesterol
  • Platelet disorders

Acquired Disorders

  • Heparin-induced thrombocytopenia (an abnormal immune reaction to heparin or any of the low molecular weight heparin preparations)
  • Antiphospolipid (antibody) syndrome
  • Myeloproliferative disorders such as polycythemia vera or essential thrombocytosis
  • Cancer or cancer treatment including specific chemotherapy medications
  • Pregnancy, oral contraceptives or hormone replacement therapy (HRT)
  • Thrombotic thrombocytopenia purpura (TTP)
  • Paroxysmal nocturnal hemoglobinuria (PNH)
  • Disseminated intravascular coagulation (DIC)
  • Nephrotic syndrome
  • Inflammatory bowel disease (IBD)
  • Behcet's syndrome
  • Thromboangiitis obliterans (Buerger' disease)
  • Previous history of deep vein thrombosis (DVT) or pulmonary embolism (PE)
  • Post surgery or trauma
  • Obesity
  • Economy Class Syndrome

After your visit

You will initially meet with either a nurse clinician, resident. or fellow who will review your information and begin the documentation process. The diagnosis and treatment of blood clotting disorders involves three main areas:

  1. Thorough history and physical examination
  2. Comprehensive laboratory testing
  3. Patient management and recommendations

Depending on the specific type of blood clotting disorder, you may be sent for specialized blood tests and imaging tests. Cleveland Clinic's Tomsich Pathology Laboratories offers an extensive range of diagnostic laboratory tests. Results and recommendations are discussed with your doctor by experts in vascular medicine, hematology, and laboratory medicine.

You will then meet with your Center physician who will review your records and take a medical history, perform a physical exam, and advise on consultations with other specialists within the Center as needed. If you need to meet with one of the multidisciplinary specialists, you will see the specialist within 1 to 2 days. The Thrombosis Center physician will provide you with a diagnosis and plan of care.

The Thrombosis Center physicians and/or Geneticists are also available to evaluate family members who are at risk for genetic or hereditary blood clotting disorders.

How long will you need to stay at Cleveland Clinic?

To complete all testing, you will need to stay in the Cleveland area for 1 to 2 days.
