The surgical steps of splenic artery embolization include: disinfecting and spreading the towel, anesthesia, puncture, imaging and embolization. 1. Disinfecting and spreading the towel: the patient takes the supine position, exposes the groin area, disinfects it three times with iodophor, and spreads the sterile sheet to ensure that the surgical area is strictly sterile. 2. Anesthesia: local infiltration anesthesia in the groin is usually used, commonly used lidocaine diluted in half and then anesthetized layer by layer. 3. Puncture: find the femoral artery, puncture the femoral artery with a guide wire and guide it upward. 4. Angiography: Insert the guide wire and catheter into the splenic artery under angiography and carefully insert the distal splenic artery. 5. Embolization: Sclerosing agent is injected into the distal splenic artery through the catheter to embolize the splenic artery, after which the guide wire and catheter are carefully removed. Splenic artery embolization is widely used, but it is not suitable for all patients with giant spleen. They should be evaluated by a doctor before deciding whether or not to undergo splenic artery embolization.
