Anterior Spinal Artery Syndrome - Confused!!!

[StressedMedStud]

In First aid 2012, p. 444, it says if anterior spinal artery is damaged you get decreased contralateral propioception (medial leminiscus/dorsal column)


HOWEVER in wiki and in a ques i'm doing from qbank, it says for anterior spinal artery ischemia/damage, the medical lemniscus/dorsal column is intact!!!!!!!!!!


Is First Aid wrong or is my qbank/wiki wrong??????/

I'm confused!

ASA causes medial medullary syndrome..The link says..it damages medial leminiscus pathway as well..

Oh snap, so if it ASA is lesioned at medulla you get different symptoms from when it is lesioned at the level of spinal cord!!!

When lesioned at medulla, it is called medial medullary syndrome, when lesioned at spinal cord it is called anterior spinal artery syndrome!!

Ahhhhhh i get it now!

They have an errata for that p 444 ASA entry, for what it's worth.

I would believe Kaplan Qbank over anything FA says.

Yeah, the dorsal column is fine in medial medullary syndrome. You're damaging the medial lemniscus, which is why you get contralateral loss of vibration/crude propioception.
