Hi, im new to this group and my mother just had hemorrhagic stroke, shes in critical condition and the neuro Dr sent her for an angiogram they found out that she doesn't have neither of her main arteries her carotid artieries they stop at her jaw line. They said she was born this way and the arteries in the back of her neck are the ones that have been supplying blood flow and oxygen to her brain. They said theres not much that can be done by this? That cant put stents because those arteries don't lead to the brain. Is there anything that can be done or a specialist we can talk to that might have more info, shes only 51yrs old and shes now in a comma. My mother had no other issues has always been healthy. Please help
