Abstract

A 70-year-old woman with liver cirrhosis presented with gastric varices and recurrent hepatic encephalopathy. Magnetic resonance imaging (MRI) showed a splenorenal shunt, and balloon-occluded retrograde transvenous obliteration (B-RTO) was indicated but could not be performed due to iodine allergy. We then performed B-RTO using gadoteridol, an MRI contrast medium, instead of iodine contrast and successfully occluded the shunt vessel. After the procedure, hepatic encephalopathy did not recur, and the size of the gastric varices was reduced. This experience may aid in the management of iodine-allergic patients requiring interventional radiological treatment.
