Abstract

要旨:症例は,59 歳男性.後頸部痛を主訴に受診した.頭部MRI にて後下小脳動脈(posterior inferior cerebellar artery; PICA)起始部を含んだ右椎骨動脈解離性動脈瘤(PICA-involved type),最長径15 mm を認めた.直達手術で動脈瘤近位部の椎骨動脈およびPICA 起始部のみを遮断し,動脈瘤を盲端化した上でPICA を椎骨動脈にside-to-end anastomosis (PICA transposition)にて治療し,神経脱落症状なく退院した.PICA-involved type の椎骨動脈解離性動脈瘤に対するPICA 血行再建術の治療戦略として,他の治療方法と比較してPICA transposition の優れた点について報告する.
