Phlegmasia cerulea dolens
Background
- "Painful Blue Leg"
- Massive iliofemoral occlusion due to venous thromboembolism
- Extensive vascular congestion and venous ischemia
Risk Factors
- Age 50-60s
- Malignancy (20-40%)
- Inherited thrombophilia
- Pregnancy
- Trauma/surgery
- Immobilization
- IVC filter
- 10% of cases are idiopathic and occur in patients without risk factors
Clinical Features
- Sudden severe leg pain
- Swelling and edema (bleb/bullae)
- Cyanosis
- Venous gangrene
- Compartment syndrome
- Arterial compromise
- Shock
- Often preceded by phlegmasia alba dolens
Differential Diagnosis
Clinical Spectrum of Venous thromboembolism
- Deep venous thrombosis (uncomplicated)
- Phlegmasia alba dolens
- Phlegmasia cerulea dolens
- Venous gangrene
- Pulmonary embolism
- Isolated distal deep venous thrombosis
Only 40% of ambulatory ED patients with PE have concomitant DVT[1][2]
Evaluation
- Clinical diagnosis
- Duplex US
- Contrast venography
Management
- For mild, non-gangrenous form: Conservative management
- Steep limb elevation
- Fluid resuscitation
- Heparin: 80-100U/kg followed by infusion of 15-18U/kg/hr
- Vascular surgery consult for emergent thrombectomy
- Interventional radiology consult for emergent catheter-directed thrombolysis
- Thrombolytic therapy: Alteplase (1mg/min to total of 50mg) distal to thrombus
Disposition
- Admit
