Hello, My dad has been admitted to hospital because he was experiencing terrible pain in his chest and was feeling very uneasy. After a scan was done the doctors found out that he his aorta had strated leaking. Now the leaking aorta has formed a blood clot and has stopped the leak. He is unconcious right for the day he was admitted. It is now 3 days that he is unconcious and in the ICU. He had also gone through an angoplast a few years ago and also has pressure problem. He is about 75 years of age. Could you please suggest what is the best option or surgery taking into account all his medical problems and age that can be done for him. Also if surgery is done what are the chances of survival after surgery for a 75 year old man. Thank you for your help
