Abstract
Percutaneous transhepatic obliteration (PTO) can facilitate antegrade embolization of variceal veins. We herein report three patients who underwent percutaneous transhepatic sclerotherapy(PTS) or percutaneous transportal outflow-vessel-occluded sclerotherapy (PTOS) for isolated gastric varices. PTS was performed in Cases 1 and 2, and PTOS was performed in Case 3. Technical success was achieved in all patients without a decline in liver function; however, lack of a therapeutic benefit with rupture of esophageal varices occurred in Case 3. Case 3 had a history of pylorus gastrectomy plus Billroth-I reconstruction for gastric cancer and multiple feeding veins existed. PTO-related procedures are good treatment options for isolated gastric varices, but clinicians should be aware of the risk of treatment failure, especially the cases which have multiple feeding veins.
