Phlegmasia Cerulea Dolens

OVERVIEW

  • Massive venous thrombosis of deep and collateral venous system causes obstruction to venous outflow
  • Ensuing venous congestion compromises arterial flow
  • Limb-threatening condition
  • Part of a spectrum with Phlegmasia Alba Dolens and venous gangrene

CLINICAL FEATURES

  • Sudden onset colour change in leg
  • Severe venous congestion
  • Venous gangrene (skin, subcutaneous tissue and muscle)
  • Shock
  • Arterial insufficiency
  • Fluid sequestration

In Phlegmasia Alba Dolens (PAD), thrombosis spares collateral veins. Venous drainage is decreased but still present. Lack of venous congestion differentiates this from PCD.


INVESTIGATION

  • Urgent Doppler ultrasound
    • Non-compressible veins
    • Absent respiratory variation at level of iliac vessels
  • CT venogram
    • Assess clot burden including pelvic/IVC vessels
    • Map for intervention

MANAGEMENT

Limb-threatening condition.

Management is controversial and evolving – options include:

  • Anticoagulation — Heparin bolus 80 IU/kg then 18 IU/kg/hr
  • Thrombectomy
  • Catheter-directed thrombolysis or systemic thrombolysis

COMPLICATIONS

  • Venous infarction leading to gangrene
  • PE
  • Post-phlebitic syndrome
  • Fluid sequestration in the affected limb and SIRS leading to hypotension and shock
  • Arterial insufficiency due to congestion
