III. Pathophysiology

  1. Normal Venous valves prevent backflow
    1. Distal to Proximal vein backflow
    2. Superficial to Deep vein backflow
  2. Incompetent valves allow backflow when legs relax
    1. Results in distal venous Hypertension
    2. Primary etiology for Chronic Venous Insufficiency

IV. Symptoms and Signs

  1. Initial Changes
    1. Varicose Veins
    2. Tan or reddish brown Skin Color changes
    3. Weeping and excoriated skin
    4. Pedal edema
  2. Later Changes
    1. Lipodermatosclerosis
      1. Induration at medial ankle to mid-leg
  3. Advanced Changes
    1. Brawny Edema above and below fibrotic area
    2. Ulcerations

V. Complications

  1. Venous Stasis Ulcers
    1. More common in older women
    2. Chronic and often recurrent
  2. Postphlebitic Syndrome
    1. Chronic Leg Edema
    2. Lipodermatosclerosis (see signs above)
    3. Deep Venous Thrombosis
    4. Superficial Thrombophlebitis
    5. Pigmentation
    6. Ulceration
  3. Overlying Skin Changes
    1. Eczema
    2. Cellulitis and other secondary infection

VI. Diagnosis

  1. Duplex Ultrasonound (B-Mode and Directional Pulse)
    1. Can accurately assess venous reflux
    2. Can also be used to assess Arterial Insufficiency
      1. With Ultrasound ankle/brachial index (See below)
  2. Descending Venography
    1. Not as accurate as Duplex scanning

VII. Management

  1. Confirm No Arterial Insufficiency
    1. Assess before managing Venous Insufficiency
    2. Ankle-Brachial Index
      1. Blood Pressure measurement
      2. Doppler Ultrasound measurement
  2. General measures
    1. Take regular walks
      1. Leg muscle activity promotes better venous return
    2. Avoid prolonged standing in one place
    3. Elevate Legs above Heart
      1. Perform 30 minutes each 3-4 times daily
      2. Elevate the foot of the bed to raise legs overnight
    4. Graduated Compression stockings (Jobst Stockings)
  3. Intermittent Pneumatic Compression Pumps
    1. Indications
      1. Obesity
      2. Moderate to Severe edema
    2. Contraindications
      1. Uncompensated Congestive Heart Failure
  4. Diuretics
    1. Short term use
    2. Indications: Severe edema

Ontology: Venous Insufficiency (C0042485)

Definition (MSH) Impaired venous blood flow or venous return (venous stasis), usually caused by inadequate venous valves. Venous insufficiency often occurs in the legs, and is associated with EDEMA and sometimes with VENOUS STASIS ULCERS at the ankle.
