Venous thrombosis · ultrasound
- Major finding
- Non-compressible vein
- B mode
- Lumen and intraluminal material
- Doppler
- Flow and variation
- Interpretation
- Segment and clinical context
Morphological description
Identify the segment, calibre, compressibility and visible material; document the extent examined.
Causes and diagnostic direction
Clinical probability depends on factors including immobility, surgery, cancer and previous thromboembolism.
Differential diagnoses
Artefact and insufficient pressure may mimic abnormality; chronic venous changes can complicate interpretation.
Pitfalls and limitations
A still image cannot demonstrate compression; absent colour flow alone does not confirm thrombosis.
Take-home message
Combine correctly performed compression, venous mapping, Doppler and clinical probability.
