is that artery actually an arteriovenous malformation(AVM)?there are certain procedures that can be done on the actual artery itself that would probably lessen your pain and take away any possible risk of rupture there too.there are many different types of arterial malformations out there that good neurovascular interventional radiologist can actually fix for you(these particular types of specialists really can do some pretty amazing things all done thru the actual arteries in a radiology suite).have you consulted a neurosurgeon who is really familiar with vascular malformations,or been seen by the type of radiologist i just mentioned for at least an eval and consult of your situation?was this found upon doing an MRI?ifso,do you have an actual copy of that MRI in your posession?if you could post exactly what the summary states about that artery area it would be really helpful.
this in and of itself,the inoperable spondy,wouldn't really be considered an actual "disability" but a condition you have.like a chronic pain type of condition caused by the arterial malformation.marcia
