Study Notes
Phlebothrombose
-
Definition: Deep veins are completely or partially blocked by a blood clot. Primarily affects the inferior vena cava. Also known as deep vein thrombosis (DVT).
-
Symptoms: Often asymptomatic (only 10% show typical symptoms). Common symptoms include: swelling (especially in the calf), dull pain, cyanosis (bluish discoloration), increased body temperature, feeling of tightness/heaviness, and visible vein prominence.
-
Diagnosis: Includes medical history review, ultrasound of the veins, contrasted CT scan (CT angiography) to visualize blood vessels, electrocardiogram (ECG) to evaluate heart if blood clot in the heart suspected, and blood tests (D-dimer testing). D-dimer is a protein released when a blood clot dissolves. elevated levels may indicate a clot.
-
Causes: Factors impacting blood flow (stasis), damage to vessel walls, and blood characteristics (hypercoagulability). These are often summarized by the Virchow triad:
-
Circulatory factors: slowing of blood flow (immobility, prolonged sitting), conditions like varicose veins, heart failure.
-
Vessel wall factors: damage/inflammation of blood vessel walls.
-
Blood factors: blood clotting too easily (e.g. high levels of clotting factors, low levels of anticoagulants) Conditions like cancer, medications, genetic predisposition, pregnancy.
-
Treatment: Often involves blood thinners (heparin, anticoagulants) to prevent further clotting. Mechanical methods such as compression stockings and support hose, thrombolysis (dissolving the clot), and/or surgical removal of the clot may be used in some cases if drugs are not an option or if the clot is large.
-
Complications: If the clot travels to the lungs, it can cause a pulmonary embolism (PE). Depending on the location and size of the clot other complications may occur.
Classification of Phlebothrombosis
- Pelvic vein thrombosis
- Femoral vein thrombosis
- Popliteal vein thrombosis
- Small leg vein thrombosis
Prognosis and Prevention
- Prognosis: Depends on the size and location of the clot. Risk of PE, if the clot travels to the lungs, and long-term complications are possible.
- Prevention: Minimizing risk factors, including adequate movement, healthy diet, and avoiding prolonged periods in still positions.
