Intraoperative Visualization of Subependymal Arteries at the Atrium Supplying the Descending Motor Pathway

摘要

OBJECTIVE: We previously disclosed that damage to the subependymal arteries (SEAs) caused by coagulation of the choroid plexus at the atrium can result in infarction within the lateral posterior choroidal artery territory, followed by hemiparesis. The present study describes the intra-operative anatomical findings of the SEAs and choroid plexus at the atrium, which were verified only by a few cadaveric studies.
