From the case: Hepatic hemorrhage
Hepatic artery proper
Superselective angiograms in liver segmental arteries identified that the hepatic bleeding site is in a "watershed" area, between two of the segmental artery territories. This means that both territories could require treatment for successful control. Embolisation was not performed due to the already compromised liver function. The bleeding stopped spontaneously during the attempts at catheterisation of the smaller vessels.
