Balloon-Assisted Percutaneous Transhepatic Antegrade Embolization with 2-Octyl Cyanoacrylate for the Treatment of Isolated Gastric Varices with Large Gastrorenal Shunts

Figure 5

CT follow-up of the patient shown in Figure 2. (a) CT portal venography image obtained before percutaneous transhepatic antegrade variceal embolization showing large gastric varices with drainage by a large GRS. (b) CT portal venography image obtained 3 months after percutaneous transhepatic variceal embolization showing that the gastric varices (asterisk) and their feeding veins (white arrow) were filled with cyanoacrylate. (c) CT portal venography image obtained 1 year after percutaneous transhepatic variceal embolization showing that the cyanoacrylate in the submucosa varices had almost disappeared (asterisk), while the perifundus varices and the feeding veins (white arrow) were still filled with cyanoacrylate, similar to result observed before follow-up. Moreover, the gastrorenal shunt was reserved (black arrow). GRS, gastrorenal shunt; GV, gastric varices; SGV, short gastric vein; PV, portal vein; LRV, left renal vein; SMV, superior mesenteric vein; SV, splenic vein.
