The interventional surgery for cerebral aneurysm is very simple, just like the conventional surgery, as follows: 1. The patient has to lie on the operating table, which is in a special room, and the operating table is connected to the DSA machine; 2. After the above steps are completed, the surgeon will puncture the patient’s femoral artery and place a sheath, which is a channel that connects the outside world to the femoral artery; 5, through this channel, the surgeon will establish another channel to reach the aneurysm, which is a microcatheter; 6, after the above steps are completed, through the microcatheter channel, the surgeon will effectively embolize the aneurysm; the embolization materials are mainly spring coils, stents, and glue; 7, After the above embolization is finished, the doctor will do the imaging before the end, and the procedure will be finished after the satisfaction.
