Background
- "Milk/White Leg"
- Massive iliofemoral occlusion due to venous thromboembolism
- Spares collateral veins
- Lack of venous congestion
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]
Risk Factors
- Age 50-60s
- Malignancy (20-40%)
- Pregnancy
- Inherited thrombophilia
- Trauma/surgery
- 10% idiopathic in patients without risk factors
Clinical Features
- Pain
- Edema
- White appearance/blanching (alba)
- May progress to phlegmasia cerulea dolens
- Superficial venous system is occluded, resulting in no venous outflow
Differential Diagnosis
- Arterial embolism
- Phlegmasia cerulea dolens
- DVT
- Cellulitis
- Lymphedema
- Venous valvular insufficiency
- Superficial thrombophlebitis
Calf pain
- Achilles tendon rupture
- Calcaneal bursitis
- Cellulitis
- Compartment syndrome
- Deep venous thrombosis (DVT)
- Distal leg fractures
- Gastrocnemius strain
- Ruptured popliteal cyst (Bakers cyst)
- Superficial thrombophlebitis
Evaluation
- Clinical diagnosis
- Duplex US
- Contrast venography
- MRV
Management
- Conservative management
- Steep limb elevation
- Fluid resuscitation
- Heparin: 80-100U/kg followed by infusion of 15-18U/kg/hr
- Vascular surgery consult
- If conservative therapy fails, can consider:
- Thrombolysis: Alteplase (1mg/min to total of 50mg) distal to thrombus
- Interventional radiology consult for emergent catheter-directed thrombolysis
- Thrombectomy
Disposition
- Admit
