LOWER EXTREMITY DVT- Use the 9L linear transducer (5L in groin if big patient)
- Use the LEV preset settings on the GE machine
- PROTOCOL
- EIV
- Longitudinal grayscale
- Longitudinal color flow
- Longitudinal Doppler (get respiratory phasicity)
- CFV/GSV (“Mickey mouse” )
- Transverse with compression
- "Mickey mouse"
- Medial ear = saphenous vein/saphenofemoral confluence
- Face = CFV
- Lateral ear = SFA
- BONUS POINTS FOR BIFURCATION
- Longitudinal bifurcation of CFV into:
- Deep FV (profunda)
- FV (superficial)
- Femoral vein (FV), aka superficial FV
- Proximal FV: Transverse with compression
- Mid FV: Transverse with compression
- Distal FV: Transverse with compression (if can't get compression, get color)
- Popliteal Vein
- Transverse with compression
- Longitudinal grayscale
- Longitudinal color flow
- Longitudinal doppler + augmentation
- Check popliteal fossa for Baker's cysts
- BONUS points for calf veins
UPPER EXTREMITY DVT- Spontaneous DVT is uncommon
- More common from a central chest lesion, so check CXR first!
- CT better for central veins (can’t see beyond clavicle)
- Use L7 probe
- Start at AC fossa to find pair of brachial veins next to artery
- Protocol
- IJV
- Longitudinal color flow
- Transverse with compression
- IJV/subclavian vein confluence
- Subclavian vein (can't compress)
- Longitudinal waveform
- Contralateral subclavian vein longitudinal waveform
- Axillary vein (place patient's arm over head)
- Longitudinal color flow
- Transverse with compression
- Brachial vein
- Transverse with compression
- Cephalic vein
- Transverse with compression
- Basilic vein
- Transverse with compression
