We present a case of giant coronal varicosity causing hepatic encephalopathy and endoscopically unmanageable esophageal varices, which was eradicated by percutaneous transhepatic sclerotherapy (PTS) using n-butyl cyanoacrylate (NBCA) under balloon occlusion of the azygos vein beyond the outlet of the esophageal varices, and microcoil embolization. Evaluation of hemodynamic images of the outflow and inflow vessels, obtained by multi-detector row CT during splenic venography, enabled the development of an effective and safe treatment strategy. PTS using NBCA under balloon occlusion of the azygos vein can be used to treat esophageal varices of this hemodynamic type.
