Lymphatic System Failure: Consequences and Clinical Significance

The lymphatic system maintains fluid balance, absorbs dietary fats, and coordinates immune responses. Failure leads to:

1. Lymphedema: Protein-rich fluid accumulation → swelling, heaviness, fibrosis, recurrent cellulitis.
2. Immune deficiency: Impaired antigen transport and lymphocyte trafficking → increased infections.
3. Spread of infection: Inadequate clearance of pathogens/toxins.
4. Fat malabsorption: Chylomicrons not transported → steatorrhea, fat-soluble vitamin deficiencies.
5. Impaired wound healing: Reduced immune cell and nutrient delivery.
6. Chylous effusions: Chyle leakage into pleural/peritoneal cavities (chylothorax, chylous ascites).
7. Systemic effects: Hypoalbuminemia, malnutrition, organ dysfunction.

Early diagnosis (lymphoscintigraphy, MRI lymphangiography) and management (compression, pneumatic pumps, surgery, nutritional support) are crucial to mitigate complications.
