karl, oh no!
"safely home from the hospital" is good. "Probably scheduled" is less good. Make the effort to get clear communication and scheduling from the medical teams.
My uncle had a vascular dissection in a carotid artery back in the early '90s. It was severe, and affected him greatly, but he made significant recovery and is still with us thirty+ years later, so have hope.
My advice to you is to encourage you to to be diligent with all the follow-ups, especially any physical therapy. In my uncle's case, early effort did pay off later.
