Dural manipulation coinciding with transient asystole during lumbar spine surgery: illustrative case

As in other reported cases, each cardiovascular disturbance corresponded with either direct or indirect dural manipulation. Given the limited number of lumbar spinal cases reported to have undergone hemodynamic perturbances via dural manipulation, this case report provides evidence for the likelihood of a spinal-cardiac reflex between the cardiovascular system and the spinal dura mater. https://thejns.org/doi/10.3171/CASE24158.
