Dear Editor,

We congratulate Dr. Denys and colleagues for addressing a timely topic in their review entitled “Portal Vein Embolization: What Do We Know?” [1]. While most of the article clarifies some of the uses and controversies of preoperative portal vein embolization prior to resection, we want to point out to the readers of CardioVascular and Interventional Radiology that some statements do not accurately reflect our own group’s work and therefore must be addressed.

First, the authors state that our paper “initially reported that embolization of segment 4 branches nearly double the rate of hypertrophy of the left lobe” [2]. This statement is incorrect for two reasons: (1) right portal vein embolization extended to segment 4 is not intended to hypertrophy the entire left liver but rather to hypertrophy only the left lateral liver (bisegment 2 and 3); and (2) “the near doubling of left liver” the authors are referring to was simply a comparison of the hypertrophy rates of the left...
