Right hepatic artery as a cause of pseudocalculus in the biliary tree
- 18 Downloads
The right hepatic artery (RHA) may be the cause of a pseudocalculus in the common hepatic duct (CHD). Extrinsic pressure by the RHA on the CHD was seen in 15% of 61 retrograde cholangiograms and in 70% of 23 sonograms in which the RHA was identified. The anatomical relationship between the RHA and the CHD was confirmed by cast corrosion studies.
