Clinical trial - MMA embolization
Basics
Chronic subdural hematoma
- repetitive bless from torn bridging veins + formation of inflammatory neovascular membranes with a propensity to reepated ooze
- cSDH recurrence rate of up to 20%
- MMA embolization is a therapeutic approach to reduce recurrence of SDH
- MMA embolization complications: periprocedural stroke, vision loss (anastomoses between the MMA and ophthalmic artery), facial palsy
MMA vasculature
- main function: vascular supply to the dura mater and cranial bone
- MMA arises from the maxillary artery (external carotid artery)
- it enters the middle cranial fossa via foramen spinosum
- branches:
> petrosal branch: superior tympanic and cavernous branch
> anterior division: medial branch of sphenodial branch and orbital branch
> posterior division: petrosquamosal branch and parieto-occipital branch
