Isolated distal deep venous thrombosis
Background
- Isolated tibial or peroneal DVTs
- Up to 25% IDDVTs propagate in hospitalized patients, but incidence is lower in ambulatory patients
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]
Clinical Features
- See DVT
Differential Diagnosis
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
- US
Management
- Repeat DVT scan in 2-5 days to look for clot propagation
- May require anticoagulation for 3 months if clot extends proximally
Disposition
- Case by case basis, with discharge and follow up ultrasound as reasonable option
- Must weight risk of bleeding of anticoagulation with risk of clot propagation
