Perioperative bioccipital watershed strokes in bilateral fetal posterior cerebral arteries during spinal surgery

Conclusions The standing hypothesis would be posterior low flow infarctions resulting from intraoperative hypotension on a variation of the circle of Willis more prone to decrease in cerebral blood flow. Moreover, this case supports the hypothesis of vascular insufficiency due to intraoperative hypotension as cause of stroke during spinal surgery.
