Background
- Definition: existence of the excess fluid in the lower extremity resulting in swelling of the feet and extending upward
- Further classified as pitting (depress-able) and non-pitting
Causes of pedal edema
- Increased hydrostatic pressure
- Decreased oncotic pressure
- Increased capillary permeability
- Lymphatic obstruction
Causes Pedal Edema
- Increased hydrostatic pressure
- Decreased oncotic pressure
- Increased capillary permeability
- Lymphatic obstruction
Clinical Features
- Pedal edema
Differential Diagnosis
Pedal edema
- Gravitational
- Venous insufufficiency/thrombophlebitis
- Drugs
- CHF
- Lymphedema
- Pretibial myxedema
- Renal failure
- Liver failure
- DVT
Evaluation
Management
- Treatment is based on addressing underlying disease process
- Idiopathic edema is a diagnosis of exclusion. Other disease process, including heart failure, cirrhosis, acute renal failure, nephrotic syndrome, chronic venous insufficiency, and medication induced edema must first be considered.[1]
- Idiopathic pedal edema need not to be treated with diuretics
Disposition
- If no respiratory symptoms, most patients may be safely discharged home
- Patients should be followed up in medical clinic for further investigation and care
