What I liked: "Mr Lavin is a caring and patient person and excellent surgeon. I have an aversion to eyes, so not the easiest person for him to deal with. He readily offered an alternative solution without delay. He has extensive knowledge and explains details clearly and reassuringly. I would recommend him."
Could improve: "In my experience, nothing. He is committed to his patients."
Atrial fibrillation is a major risk factor of stroke. The top heart chambers (atria) fibrillate and stagnation of blood predisposes to clotting; the blood clot can then get dislodged into circulation and finally wedged in one of the arteries in brain cutting off blood supply and causing a stroke.
Rivaroxaban is one of anticoagulants ('blood thinning' drugs) which reduce the risk of excessive clotting and so the risk of stroke. So, the answer is yes - a previous stroke automatically places your mother in the high risk category - but she seems to be on a good treatment to reduce this risk as much as possible.
It is a very individual process. I performed an abdominoplasty and breast reduction on a 68 year lady last week, no drains, went home the day after and who is back to almost normal activity 10 days later and able to drive with normal posture. I have other patients that have struggle to gain normal posture by 2 weeks who are much younger. At the end of the day it depends on how fit and well you are to start, what is being done and how you recover from operations. For patients who are anxious it is best to talk to previous patients and maybe you should ask your surgeon to put you in touch with previous patients so that you can get more of an idea first hand.
