Are there any midlevels around who can provide some insight into aortic dissection? No big deal, it's not like it's a highly dangerous condition where around 25% of patients die before reaching the hospital. The fact that this NP's father has had both an ascending (Stanford type A) and now a descending (Stanford type B) doesn't sound too promising. Maybe...just maybe...it would be a better idea to ask, you know, the cardiothoracic surgeon who would be performing the surgical repair if you want some insight? I have a sneaking suspicion that anyone who managed to not only get into medical school, but match into a 6-year integrated cardiothoracic surgery residency (or 2-3 year CT fellowship after completing a general surgery residency) is going to be a bit more knowledgeable about a complex, multi-stage procedure for aortic dissection repair like the elephant trunk. Just a bit. Perhaps more so than a midlevel nurse practitioner who might have received their degree from a 100% online for-profit diploma mill and has only a few hundred hours of clinical training. I don't know about you, but if it were my father, I certainly wouldn't be soliciting any advice about aortic dissection repair from any physicians without a surgical background, let alone from a Facebook group of midlevel nurse practitioners!
