Background

  • Most common cause is bilaeral pedal edema
    • 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

Mechanisms of Pedal Edema
  • Increased hydrostatic pressure
  • Decreased oncotic pressure
  • Increased capillary permeability
  • Lymphatic obstruction

Clinical Features

Pitting pedal edema
  • Bilateral lower extremity swelling

Differential Diagnosis

Bilateral leg swelling

Differential Diagnosis of Pedal Edema

Evaluation

Workup

  • CBC
  • Chem 7
  • PT vs albumin (liver)
  • ECG
  • CXR
  • UA (nephrotic)
  • Consider BNP

Diagnosis

  • Idiopathic edema is a diagnosis of exclusion, must first rule out CHF, cirrhosis, renal failure, nephrotic syndrome, chronic venous insufficiency, and medication-induced edema[1]

Management

  • Treatment is based on addressing underlying disease process
    • 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
