Everything you ever wanted to know about angioplasty balloons but were afraid to ask....
from page 13:
Balloons can be created with multiple lumens or
channels so as to allow the balloon to perform
multiple functions in both the inflated and
deflated state.3 For example, a multiple lumen
balloon can be fabricated so as to allow blood to
profuse (flow) through one or multiple lumens
while the other lumens inflate to perform
This is surely more expensive than a normal balloon and I don't think it would allow for high pressure. But in my case, since my left IJV was 99% closed, when my RIJV was first ballooned, it cut off the flow. A mulitlumen balloon would've allowed the flow to continue through the balloon itself which might have been easier on the brain.
If it were possible to determine which jugular had less flow as seen in the pre-imaging doppler and to start with that one, that might also be a solution. It would be good to minimize possible insult to the brain, particularly since our brains are weakened from MS and CCSVI, so a disruption of flow that could normally be handled by a brain without issue might not be as easily handled by our brains.
