Zheng Ren had seen some of the medical records before. Because of Mayo's cover-up, he did not see any stent surgery or removal surgery for renal artery stenosis.
However, in the subsequent email communication, the Mayo Clinic's research team also admitted this point. However, they only sent over the procedure of the stent surgery, but the removal process and the patient's condition were missing.
This was the first time Zheng Ren saw this.
The surgery removed the stent that had narrowed the renal artery. There was nothing interesting to see during the entire surgery. Zheng Ren mainly looked at the changes in the patient's physical condition after the stent was removed.
After the stent was removed, the patient's blood pressure became unstable. In order to avoid the changes in blood pressure caused by emotional fluctuations, he used a sedative state and a ventilator to assist in breathing.
