Abstract
PURPOSE
To evaluate the technical feasibility and safety of vascular plug assisted retrograde transvenous obliteration (PARTO) for bleeding gastric varix performed in the emergent clinical setting and describe the mid-term clinical results.
MATERIALS AND METHODS
From April 2012 to January 2015, emergent PARTO was tried in total 9 patients presented with active gastric varix bleeding. After initial insufficient or failure of endoscopic approach, they underwent PARTO in the emergent clinical setting. Gelatin sponge embolization of both gastrorenal (GR) shunt and gastric varix was performed after retrograde transvenous placement of a vascular plug in GR shunt. Coil assisted RTO (CARTO) was performed in one patient who had challenging GR shunt anatomy for vascular plug placement. Additional embolic materials, such as microcoils and NBCA glue-lipiodol mixture, were required in three patients to enhance complete occlusion of GR shunt or obliteration of competitive collateral vessels. Clinical success was defined as no variceal rebleeding and disappearance of gastric varix.
RESULTS
All technical and clinical success-i.e., complete GR shunt occlusion and offending gastric varix embolization with immediate bleeding control-was achieved in all 9 patients. There was no procedure-related complication. All cases showed successful clinical outcome during mean follow up of 17 months (12-32 months), evidenced by imaging studies, endoscopy and clinical data. In 4 patients, mild worsening of esophageal varices or transient ascites was noted as portal hypertensive related change.
CONCLUSION
Emergent PARTO is technically feasible and safe, with acceptable mid-term clinical results, in treating active gastric varix bleeding.
