Study Notes
Lymph Formation and Types of Oedema
- Lymph is a fluid that contains various substances.
- Lymph is formed through Starling's Law, which describes the balance between filtration and reabsorption in capillaries.
- Oedema can be classified into two types: dynamic insufficiency and mechanical insufficiency.
- Mechanical insufficiency refers to malfunction in the lymphatic system that limits fluid transport capacity.
- Oedemas of lymphatic origin have high protein concentration and can lead to chronic inflammation and fibrosis.
- Positive Stemmer's sign, increased skin folds, and unilateral presentation are common in oedemas of lymphatic origin.
- Malfunction in the lymphatic system can be due to organic or functional defects.
- Organic changes include broken lymphatic capillaries, missing lymph capillaries, and abnormal diameter or number of collector vessels.
- Functional changes include spasming of smooth muscle and valve insufficiency.
- Primary lymphoedema is hereditary or congenital, while secondary lymphoedema is acquired.
- Primary lymphoedema can be classified into three forms based on the age of symptom onset.
- Secondary lymphoedema can be caused by trauma, surgery, tumors, cancer radiation, infection, chronic venous insufficiency, obesity, filariasis, or lipoedema.
