Successful balloon-occluded retrograde transvenous obliteration of gastric varix via pericardiacophrenic vein after embolization of portopulmonary venous anastomosis

摘要

Editor: Although the condition is considered rare, reports describing portopulmonary venous anastomosis (PPVA) have increased, paralleling the development of various imaging modalities (1). A PPVA has been noted as a potentially dangerous channel for systemic arterial embolization resulting from shunt occlusion treatments for an esophageal or gastric varix after portal hypertension, such as percutaneous trans-hepatic obliteration and endoscopic sclerotherapy (1).
