Compact microcatheters useful for neurovascular do the job are sometimes occasions essential. Every single pedicle resulting in the nidus will be superselectively catheterized and embolized with pure ethanol. The quantity and injection fee of ethanol will be depending on a preceding contrast injection with a electronic subtraction angiography (DSA) acquisition executed While using the very same syringe dimensions.

The remaining feeding arteries are at this stage too modest or much too tortuous to permit appropriate distal catheterization for Safe and sound and efficient ethanol injection.
The speed of polymerization will rely upon the lipiodol focus. The higher the dilution (a lot more lipiodol), the for a longer time it's going to acquire to polymerize permitting for deeper penetration. Glue can, nevertheless, be incredibly unpredictable and its learning curve more time for appropriate use. It is adhesive and might recanalize following a while.
