Liu, 84, was hospitalized in our neurology department due to cerebrovascular disease. During the period, abdominal ultrasound revealed a left kidney occupancy, and CT-enhanced scan showed the presence of a 3-cm-sized occupying lesion in the left kidney, which was diagnosed as kidney cancer. Because of the patient’s age and serious cardiovascular and cerebrovascular diseases, surgery and anesthesia were risky, and the family did not accept the surgery. However, there is a relationship between the patient’s back pain and the renal occupancy, and the elderly have a need to improve their symptoms. This put the patient and the family in a dilemma. Dr. Kong, the supervising physician, recommended minimally invasive interventional treatment, i.e. transrenal artery renal cancer embolization, to the family after understanding the possibility of interventional treatment from the catheterization laboratory. Another difficulty of treatment is that the patient has cognitive impairment and may not fully cooperate during the local anesthesia surgery. It has happened that the patient pulled out the drip by himself during the infusion and got out of bed. Too much damage and bleeding, and the radial artery only needs to be compressed for 6 hours after surgery, and it does not affect their normal activities such as walking on the ground, so the patient will not have femoral artery complications after surgery because they cannot be forced to lie in bed, and then they may cooperate with the treatment to the maximum extent, while giving moderate sedation. After adequate preoperative discussion and preparation, and full communication with the family, the patient underwent embolization of the left renal tumor via the right radial artery access in the morning of November 2. After the operation, the patient’s back pain was significantly relieved and he was discharged smoothly, and the patient’s family was very satisfied with the treatment in our hospital. Surgical treatment of kidney cancer is the first choice for kidney cancer treatment because of its precise efficacy and high cure rate. However, for some patients with advanced stage or advanced age, which are difficult to be treated surgically, interventional treatment also shows its good efficacy. Figure 1 shows the abdominal CT shows the left middle kidney occupancy – left kidney cancer Figure 2 shows the DSA angiography shows the rich blood supply of the left middle kidney kidney cancer Figure 3 shows the catheter super-selected renal artery branch angiography to clarify the blood supplying vessels and the next step of embolization treatment.
