So now we just wait for the call that she's crashed and in the ER with a chest cath sticking in her for emergency dialysis.
She should at least visit a vascular surgeon to make sure the scar tissue is not an issue for a PD catheter. If not there is such thing as urgent PD where PD is initiated right after surgery with low volume fills of solution while the patient remains laying down on their back. You can google urgent start PD to learn more about it.
