Thanks for your query and I apologise for taking so long to reply over the holiday period.
I think I have tried to answer your question before. It is true that the two vertebral arteries pass over the sides and the front of the medulla oblongata before they unite to form the basilar artery. However, “compression” of the medulla oblongata by a vertebral artery in a young woman must be extremely rare, and even if there is an element of compression, it’s highly unlikely that this would ever cause stroke or a transient ischaemic attack. I suspect that the impression of “compression” which was reported after whatever form of imaging you have had is simply an incidental finding. The symptoms that you describe could not be from a vertebral artery compression of the medulla.
If you are concerned about your symptoms and you want to know more then I suggest arrange to see a good neurologist.
