Vasa nervorum

Vasa nervorum are small arteries that provide blood supply to peripheral nerves, specifically to the interior parts of nerves,^[1] and their coverings.^[2]

Associated pathologic conditions

Small vessels like vasa vasorum and vasa nervorum are particularly susceptible to external mechanical compression.^[2] A decrease in blood flow through the vasa nervorum has been implicated in the development of diabetic neuropathy. Arteritis of the vasa nervorum leads to mononeuritis multiplex or polyneuropathy.^[3] Occlusion of vasa nervorum at the level of the epineurial arterioles leads to ischemia of nerves, leading to vasculitic neuropathy.^[3]^[4] and has been implicated as the cause in a few cases of facial nerve paralysis.^[3] During invasive diagnostic or therapeutic procedures, injecting a vasoconstrictor close to a nerve can reduce perfusion to its supplying vessel, risking ischemic nerve injury.^[5]
