Liver Doppler
- This is usually performed as an adjunct to an upper abdominal scan
- If indicated Doppler assessment may be performed in isolation
- Requested by referring clinician
- A combination of ultrasound appearances suggestive of portal hypertension, these include (but are not restricted to):
- Splenomegaly, especially in the absence of another causitive condition
- Portal vein dilatation (>/= 13mm lumen)
- Varices, typical of portosystemic collaterals (e.g. para-umbilical, lieno-renal, coronary etc.)
- Liver surface irregularity consistent with cirrhosis
- Splenic vein
- SMV (if possible, often unable to be assessed due to overlying bowel gas)
- Portal vein (main)
- Left and right portal veins
- Ligamentum teres region (for paraumbilical vein varicies)
- Main hepatic artery
- Hepatic veins
- IVC
- Common sites of portosystemic collateral
- Remainder of upper abdomen if indicated
Standard Documentation:
- Colour Doppler images / clip store / PW Doppler spectral waveforms +/- clipstore of:
- Splenic vein
- SMV (often unobtainable)
- Main, left and right portal veins
- Hepatic artery
- Main, left and right hepatic veins
- IVC
- Colour Doppler images +/- clipstore of ligamentum teres region, PW Doppler spectral waveforms if para-umbilical collateral is present
- Standard documentation for upper abdomen if indicated
