Study on molecular analysis for pathological condition of liver regeneration by hepatic venous reflux disorder and its treatment approach

采用肝切除模拟系统进行解剖分析，将三阶门静脉分支灌注区分为颅尾型、前后型和多型。考虑前后型的手术方式有助于根据肝功能储备选择合理的手术方式，考虑手术方式避免充血区域并仔细检查血管解剖有助于安全可靠地执行手术。有静脉反流障碍的肝组织与无静脉反流障碍的肝组织相比，肝再生能力较差；因此，需要进一步分析病理情况。

Perfusion area for the third-order portal branches was categorized to cranio-caudal type, antero-posterior type, and multiple type while conducting anatomical analysis with using a hepatectomy simulation system. The consideration for operative procedure in relation to antero-posterior type was useful to examine a rational operative procedure in accordance with hepatic functional reserve, and the consideration for operative procedure avoiding congested area with closely examining vascular anatomy contributed to the execution of safe/reliable surgery. The hepatic tissue with venous reflux disorder tended to be poor hepatic regeneration ability in comparison with tissue without reflux disorder;therefore, further analysis for the pathological condition would be required.
