Spinal AVM Particle Embolization

A useful technique when nothing else makes sense

Post hemorrhage

Mostly PSA contribution

Some faint ASA — can u see?

CBCT raw data — ASA sulco-comissural supply

PSA supply

Fusion CBCT — sulcocomissural ASA supply

Pretty images are nice, but analysis comes from raw data. Even in a spinal AVM, high-end CBCT can show intranidal principal organizing veins — as in brain. Arrow — principal draining vein. Dashed arrows — principal tributary intranidal veins.

Embozene 500 um particle embo — these particles are colored, u can count how many are injected — individually…

Two months post embo. Reorganization of supply, as expected

Fusion

Now easier to see principal vein and its tributaries
