Reviewer’s report
Title: 
Diaphragmatic Perforation after Transcatheter Arterial
Chemoembolization of Hepatocellular Carcinoma via Inferior Phrenic Artery: A
Case Report
Version: 
1 
Date: 
06 Jan 2022
Reviewer's report:
The case report is really interesting.
I have the following comments:
1) English grammar should be improved. I suggest to the authors to have their
manuscript revised by a native speaker
2) There are some alternative options to TACE, particularly TAE (bland
embolization). This should be reported in the text citing the recent meta-analysis
(PMID: 28588882)
3) A brief comment on the other potential adverse events of TACE should be
added. In this regard, cite the very recent study (PMID: 34683182)
4) An interesting question could be: are systemic therapies , such as sorafenib,
safer? Cite the recent paper PMID: 31449860
