To the Editor,

We thank the author for his subtle reading and interest in our work. We agree with the author’s decision about “the management of high obstruction of IVC is peculiar and substantially different from that of canonical BCS.” The author stated that some serious complications including rupture of the vessel were observed during PTA for the MOVC previously but, as we performed in our cohort, we advise gradual consecutive small- to large-sized balloon usage for PTA. Other bail-out methods including surgery and liver transplantation for the treatment of high MOVC that is unresponsive to PTA or stenting must be discussed in the future.
