Complication with central line placement PICC Lung Esophagus?

To make a very long story short. My friend went to surgery, and had a central line placed. I am not sure if they did an CXR or if it is even mandatory to do so, to check placement? They did surgery for at least 2 hours and during this time her lungs and heart became fluid filled and they had to stop the sugery when she went into cardiac arrest. They later told us that the line had went thru her esophagus and into her lungs. They gave her 8 liters of fluids and who knows what else but, the fluid filled her lungs causing her heart to get squeezed and stop beating. They brought her back and was put on a ventilator. I know aboi\ut the risk for the lungs, but has anyone ever heard of a line going thru an esophagus?? ANY AND ALL INFO ON ANY OF THIS WOULD BE APPRECIATED!!! Thanks
