Differential Diagnosis
[edit | edit source]- DVT
- cellulitis, myositis, fascitis
- venous obstruction due to a tumor
- hematomas
- muscle injury
- compartment syndrome
ABC's and initial assessment
[edit | edit source]- extreme pain → compartment syndrome
Vitals
[edit | edit source]- Pulmonary embolism: SOB,↑ HR, ↑ RR, ↓ O2 sat → PE
- cellulitis → fever
Well's Score
[edit | edit source]History
[edit | edit source]- active cancer (+ 1)
- paralysis, or recent cast (+ 1)
- recent immobilization x > 3 days, major surgery (+ 1)
- history of clots, DVT (+1)
- pain - severity
- recent trauma (sports, blunt) → hematoma, muscle injury
Inspection
[edit | edit source]- swelling of entire leg (+ 1)
- collateral superficial veins (+ 1)
- erythema, sharp demarcated border → cellulitis
Palpation
[edit | edit source]- tenderness along deep veins (+ 1)
- ≥ 3 cm increase in calf circumference vs. other leg (+ 1)
- pitting edema (+ 1)
- compression of calve against the tibia → ↑↑ pain
- warmth
- distal pulses, capillary refill → ↓ in longstanding arterial disease
- passive range of motion of the toes or ankle → ↑pain in compartment syndrome
Assessment
[edit | edit source]- likelihood of alternative diagnosis (- 2)
Well’s score
[edit | edit source]- > 3 = high probability of DVT
- 1 - 2 = moderate
- 0 = low
