You will be admitted to our ward on the morning of the intervention about which you have already been informed in advance with the attending physician. The actual intervention takes place in the radiology department. First, the puncture site in the right groin is sterilely covered and anesthetized before the intervention. Using a thin needle, the usually right inguinal artery is then punctured, and a small-bore catheter is advanced through it into the iliac artery. Embolization is then performed, i.e. small vessels are closed with tiny plastic beads, thus separating parts of the prostate from the blood supply. The entire procedure is monitored by X-ray fluoroscopy. After successful embolization, the catheter and sheath are removed in the groin, and after a short impression of the artery, a firm bandage (pressure bandage) is applied. This bandage remains in place until the following morning. During the entire procedure, an analgesic as well as fluid is already infused via a venous access route. In particular, pain therapy is continued after the procedure.
