The Adamkiewicz artery (AKA) supplies pudendal nerve roots and conus medullaris. The aim of this study was to elucidate if there is any relationship between neurodegenerative changes of the Onuf nucleus (ON)-pudendal nerve ganglia complex secondary to vasospasm of the AKA after spinal subarachnoid hemorrhage (SAH). ⋯ ON-pudendal nerve ganglia complex degeneration secondary to vasospasm of the AKA may be a cause of urinary retention after spinal SAH.
