Reviewer's report:
Major revision
Firstly, the authors should show in greater detail why the cause of hepatic artery
dissection is splenectomy. I think that the cause of hepatic artery dissection is the
existence of intraoperative hepatic artery dissection. I want to know the rate of
hepatic artery dissection in all cases with splenectomy. In addition, I think that
the causes of intraoperative hepatic artery dissection are arteriosclerosis.
Therefore, you should show the histopathology of hepatic artery of removed
liver, medical history of diabetes mellitus/hypertension/hyperlipidemia, and
arterial calcification of preoperative CT examination.
Secondly, I also think that the other cause of hepatic artery dissection is injury by
the operative technique. You should show the operative technique in general and
these cases on particular hepatic ligation and reconstruction methods.
Thirdly, you should show the strategy of diagnosis and treatment for hepatic
artery dissection after LDLT as the flow chart. In addition, I cannot understand
about the selection of IVR treatment (embolization? or stent? or conservative?).
