PROBLEM TO BE SOLVED: To provide a method and a system for predicting a blood flow distribution amount that varies according to a change in s structure of a vascular system network after a blood vessel operation represented by bypass surgery, etc.SOLUTION: A method for predicting a blood flow distribution amount includes a process for estimating a peripheral vascular resistance in the environment on the downstream side for each blood vessel in a blood vessel exit part which is a boundary area of a blood vessel setting range after an operation and the environment on the downstream side, and a process for setting a blood vessel shape after the operation and estimating a blood flow distribution amount by using the peripheral vascular resistance for the correction of an exit boundary pressure.COPYRIGHT: (C)2015,JPO&INPIT【課題】バイパス手術等に代表される血管手術後の血管系ネットワーク構造変化に伴って変動する血流配分量の予測方法及びそのシステムを提供する。【解決手段】手術後の血管設定範囲とその下流側外界との境界領域である血管出口部において、血管ごとに下流側外界での末梢血管抵抗を見積もる過程と、術後の血管形状を設定し、出口境界圧力の修正に、前記末梢血管抵抗を用いることで血流配分量を推定する過程とを備えてなる、血流配分量予測方法である。【選択図】図2
