do you think that reflux in the vertebrobasilar arterial system (and possible associated slowing of blood flow into the brain) can exacerbate MS symptoms? If so, what options would you consider to fix the reflux in the vertebrobasilar arterial system?
If i understand your question, you are speaking about reflux in the vertebrobasilar ARTERIAL system.
Reversal of blood flow in the VB system is usually referred to as Vertebrobasilar insufficiency and is often part of the subclavian steal syndrome.
This is a very different entity. For a variety of complicated reasons, there is INFLOW obstruction to the arm arteries. The body gets blood to that limb by reversing the flow in the vertebral artery as a bypass of blockage. GO back to the highway analogy. The cars will find a way around the traffic jam.
When blood flow reverses in the vertebral artery, it is possible to STEAL blood from the brain (NOt good). In a patient with already reduced cerebral blood flow, this is not helpful.
Does that help. And when do you want to take your medical school exam
