    • ...However, these drugs and techniques are not currently in wide use due to reasons such as side effects, complications and facility limitations. New and safe methods that can be performed at any facility are thus needed.We thus considered 2-stage PVE as a new, highly safe method to facilitate liver regeneration following PVE that can be performed at any facility. To describe 2-stage PVE more concretely, during preoperative PVE involving right lobectomy and extended right lobectomy, the right posterior branch is embolized after right anterior branch embolization, and during preoperative PVE involving right trisegmentectomy, the medial branch is embolized after right branch embolization. In rats, a laparotomy is required for PLV, but in clinical settings, performing PVE by percutaneous transhepatic portal puncture is better and less invasive. In the present study, the rat 90% PVL model was used to investigate 2-stage PVE. If the present research model assumes preoperative PVE involving trisegmentectomy, group A represented 1-stage embolization of the right portal branch, group B represented 1-stage embolization of the right and medial portal branches, and group C represented 2-stage embolization of the right and medial portal branches.As far as animal models for PVE are concerned, numerous studies have been reported using the rat 70% PVL models first described by Rous and Larimore [...
