Ⅰ．はじめに
　Watershed shift（WS）は，もやもや病に対する浅側頭動脈-中大脳動脈（superficial temporal artery-middle cerebral artery：STA-MCA）バイパス術後の，局所脳循環変化による脳虚血の原因の1つとして提唱された概念である⁷⁾．WSに伴う脳梗塞は，もやもや病に対するバイパス術全体の1.2〜5.7%に起こる^7,16)．これまでWSを画像で直接確認した報告はない．今回われわれは，成人もやもや病術後に過灌流症候群（cerebral hyperperfusion syndrome：CHPS）を来し，その後WSが原因と考えられる脳梗塞を来した1例を報告する．
