Find out how Dr Gal Yaniv treated this case performing a staged MMA embolization.
PRE – Embolization CT
The neurosurgery team decided not to perform cSDH evacuation due to the fragility of the patient as well the absence of any laterality of neurological symptoms.
A decision was made to perform a staged MMA embolization. The first side was the left.
The first session was performed using:
The EnvoyTM was placed in the RT CCA.
After choosing optimal A and B positions, a Bi-axial system composed of PhenomTM Plus over an ApolloTM microcatheter over a HybridTM microwire was advanced into the dominant anterior branch of the MMA.
After verifying the second marker of the ApolloTM microcatheter was placed above the petrous branch origin, 0.2 cc of OnyxTM 18 was injected with proximal occlusion of the branch. The microcatheter was withdrawn.
The control angiogram did not demonstrate the MMA.
The procedure was concluded with no complications.
