Plug-assisted retrograde transvenous obliteration (PARTO) is a modified balloon-occluded retrograde transvenous obliteration (BRTO) procedure, devised in South Korea, in which a shunt vessel is embolized with gelatin sponge under vessel blockage by a vascular plug instead of a balloon catheter. PARTO has the advantages of resolving several problems of BRTO: PARTO can simplify a procedure with no need to downgrade, and it can shorten the patient’s resting time with no need for overnight retention of a balloon catheter. PARTO can be the first interventional treatment option for gastric varices and hepatic encephalopathy with a comparable clinical outcome to BRTO in cases in which the vascular plug can be appropriately placed.
