18/Now you know the anatomy of the major arterial supply to the dura & how they can be used to treat SDH. So the next time someone questions you about dural blood supply, you can attack it MMA style! Check it out for yourself! www.ajnr.org/content...

17/ In this month’s AJNR, Chen et al. found in MMA embolization for chronic SDH, additional surgical evacuation did not provide any additional benefit in higher-risk populations!

16/SDHs have vascular septa that can bleed & cause enlargement. These septa are supplied by the MMA, so embolization of the MMA reduces the vascularity & bleeding!

15/This results in the major vascular territories of the dural arterial supply.’ You can see the MMA covers the most territory & the territories over the convexities. This is why it is targeted in embolizations.

14/Anterior meningeal artery is small. It arises from both the ethmoidal arteries. Remember: it supplies the dura overlying the ethmoids, so it would make sense it arises from the ethmoidal arteries

13/Remember the PHARYNX is in the back of the mouth, so the ascending PHARYNGEAL supplies the dural around the back

12/Posterior meningeal artery is much smaller than the MMA. It’s from the ascending pharyngeal artery and supplies the dura to the posterior fossa, but also has anastomoses with the posterior division of the MMA.

11/Anterior division passes under the pterion, a junction of four calvarial bones. This renders it vulnerable to trauma & resulting epidural hemorrhage. Remember: the anterior part of an MMA fighter is very vulnerable to injury!

10/Ant division is larger & has branches that anastomose to the contralateral MMA. Remember: MMA fighters touch gloves before the fight, and gloves are out in front So ant division touches the opposite side like touching gloves before a fight.

9/Post division is smaller & has branches covering the posterior convexity. Its territory is draped over the back of the calvarium the way MMA fighters drape flags over their backs after winning.

8/MMA then splits into anterior (frontal) & posterior (parietal) divisions. I think it looks like an MMA fighter celebrating their victory with their two arms in the air

7/After spinosum, MMA takes a sharp, corkscrew-like turn following the curvature of the middle cranial fossa. This gives a characteristic angio appearance—always look for the sharp turn. Remember: the artery SPINs after SPINosum

6/MMA enters foramen spinosum. Foramen ovale & spinosum together look like a high-heeled shoe footprint. Spinosum is the heel. Remember: high heel spike and SPinosum & SPike sound alike. I always look for this footprint.

5/The largest & most important is the middle meningeal artery or MMA, from the internal maxillary artery or IMAX. Remember: Mortal Kombat & other MMA type fighting is shown in IMAX theaters!

4/Although individual vessels feed the dura, it’s actually more as a vascular network. Anastomoses among the dural vessels are common and plentiful, as is common with external carotid networks.

3/But dural vascular anatomy & supply are important, especially now that MMA embolizations are commonly for chronic recurrent subdurals. It also important for dural arteriovenous fistulas.

2/Everyone knows brain blood. Circle of Willis anatomy is king, while the vascular anatomy of the blood supply to the dura is the poor, wicked step child of vascular anatomy that is often forgotten

1/Ready for a throw down? MMA fights get a lot of attention, but MMA (middle meningeal art) doesn’t get the attention it deserves. This month’s @theAJNR tells you all you need to know! www.ajnr.org/content...
