Bypass surgery

I have a total of 8 stents in my coronary arteries and have been told that I need bypass but it would be nearly impossible to find a surgeon to do it. I do have other health issues, diabetes, high blood pressure, history of PE, multiple spine surgeries. I am overweight but am working on that. My LAD is 90% blocked and have been told that they cannot put anymore stents or balloon it . I'm taking a lot of medications and feel like I'm just sitting around waiting to die. I am 67 years old and have a strong family history. I have also been told that there is not enough artery to attach a bypass to. Any suggestions?
