Interesting assuming your flair is correct and you are not in medicine it seems more likely there was a miscommunication. I've seen bad outcomes but i have never seen or been involved in a "coverup." In PACU Im on the phone with the family/proxy immediately informing them of even relatively mild complications like blood loss requiring transfusion (1-2 units not MTP).At least in general surgery, the patient/their PCP will see what was done on post-op imaging. You can't hide from radiology!
I have had an experience in a hospital like this, as the mom of a patient. The procedure was absolutely botched and we did not find out til later from a nurse who didnt realize they hadnt told us the entire truth. It changed the procedure for pyxis picks in our local hospital, because they picked the wrong medication and it went through two nurses and a pediatrician and was administered to my newborn, premature son.Every business is going to protect its own interests, and I consider doctors a business entity as well as the practices and hospitals. Mistakes are understandable but for a mistake to make it through 3 medical professionals and not be caught til hours after the fact is inexcusable.All this to say, mistakes happen and even on a big scale. I wouldnt think it uncommon for this sort of thing to happen.
