Low probability of DVT

Intermediate/high probability of DVT

Start anticoagulation (Chapter 103)
Consider causes of DVT (Table 56.4)

Duplex scan of proximal leg veins Interim dose of LMW heparin if indicated

Positive

Negative

DVT excluded

Repeat duplex scan in 6-8 days to confirm no DVT

DVT excluded
Pursue other causes of leg swelling (Table 56.3)
