Ethanol infusion in the vein of Marshall
Following confirmation of the amenable VOM, a guidewire (Cruise; Asahi
Intecc, Aichi, Japan) and an over-the-wire balloon catheter (1.5 or 2
mm) (EmergeTM; Boston Scientific, Marlborough, MA,
USA) were inserted into the VOM using double guiding catheters (Figure
2B). A VOM angiography was performed while locating the inflated balloon
at most distal site of the VOM (Figure 2C). Subsequently, anhydrous
ethanol of total 5 mL was infused into the VOM. EIVOM was divided into
two parts, which were performed at the most distal and proximal sites in
the VOM according to a previous study (Figures 2C &
D).11
