My 87 year old brother-in-law is in a nursing home recovering from Hip Surgery 2 weeks ago. He is quite weak and feeling discouraged. Now they want to do Carotid Artery Surgery. Should he get it done? How dangerous is it and should I put a stop to it? He also has two blocked arteries behind his heart that they cannot operate on because he would not survive the surgery. He has an abdominal aortic aneurysm. He has an inoperable diverticula on his lower esophagus with swallowing difficulties that could cause aspiration pneumonia. He has Alzheimer's, balance problems, and has to eat pureed food. I am HPOA and his advocate. What should I do?
