For patients with hepatocellular carcinoma, intra-arterial chemotherapy can be applied as an alternative treatment if there is concern about the occurrence of hepatic failure during transcatheter arterial chemoembolization (TACE) due to main portal vein thrombosis or if the patient does not respond to TACE. Various complications due to the port system for intra-arterial chemotherapy have been reported so far, but no case has been reported in which a coil for port catheter fixation was extruded into the gastrointestinal tract lumen. We report a case of a patient who developed persistent gastrointestinal bleeding after a coil for port catheter fixation was extruded into the gastrointestinal tract lumen.

Gastric variceal bleeding has a poor prognosis and a high mortality rate. Balloon-occluded retrograde transvenous obliteration has traditionally been applied in the treatment of gastric varix. Recently, plug-assisted retrograde transvenous obliteration (PARTO) has been widely and popularly applied for the treatment of gastric varix. There have been no reports of cases in which PARTO was performed in patients with both gastrorenal shunt and gastrocaval shunt. We report a case in which PARTO was performed on a patient with gastric varix who had both a gastrorenal shunt and a gastrocaval shunt.
