A JR4 catheter is inserted into the CS to identify the ostium of the VOM. Subsequently, a guide wire supported by an OTW balloon catheter is advanced into the VOM. The balloon is inflated at 6-8 atm pressure in the VOM. Ethanol is infused into VOM from distal to proximal with 3ml each time within 1-2min. After the distal EI-VOM, the balloon is deflated and adjusted to the middle part of VOM. The EI-VOM procedure in the proximal and middle part of VOM should be the same as that in the distal. After three times of EI-VOM, the contrast is injected into VOM to make it permeable and dispersed to observe the effect of alcohol ablation.
