Title: Innovative angiography: a new approach to discover more hepatic vein collaterals in
patients with cirrhotic portal hypertension
Version: 0 Date: 07 Feb 2023
Reviewer's report:
The paper deals with an important topic, authors incorporated innovative method of visualization
of hepatic vessels in patients with portal hypertension, during TIPS. Rationale for the study is
clear, discussion is well written and highly informative.
Several improvements are highly recommended:
1. More details on innovative angiography procedure - to explain  parameters of contrast
injection, why specific values, e.g. pressure, have been chosen.
2. Results section could easily be presented in different form, e.g. table, which would make it
easier to read.
3. More images which would directly compare the findings in regular and innovative
angiography would be valuable.
