Preoperative detection method and a postoperative detection method for neuromapping

A postoperative detection method for neuromapping, performed by using an electrode catheter system, the electrode catheter system comprises an interventional catheter provided with an electrode element that can release an electrical signal toward an inner wall of a renal artery blood vessel on one lateral side of a body of a patient;

• a pressure sensor for intervening to the renal artery blood vessel;
• and a data processing module connected with the pressure sensor, wherein the pressure sensor is arranged in another renal artery blood vessel on the other lateral side of the body of the patient;
• wherein the method comprises:
• releasing an electrical signal towards the renal artery blood vessel on one lateral side of the body of the patient by the electrode element;
• monitoring a heart rate by an electrocardiogram monitoring module, and monitoring a blood pressure change in said another renal artery blood vessel on the other lateral side of the body of the patient by the pressure sensor, and determining a nerve activity degree by judging whether the heart rate and the blood pressure change reach certain thresholds;
• if the heart rate and the blood pressure change are lower than the thresholds, determining that the nerve activity degree has been reduced to a standard value;
• if the heart rate and the blood pressure changes still reach the thresholds, determining that the nerve activity degree still remains strong.
