Coil-assisted retrograde transvenous obliteration (CARTO) for the treatment of gastric varices via a single access route using steerable microcatheter: a case report

摘要

Representative computed tomography during arterial portography image showing gastric varices (white arrow) before treatment. Three-dimensional volume rendered images of gastric varices reconstructed from computed tomography during arterial portography. The main feeding vessels of gastric varices are the posterior and short gastric vein (①). The varices (②) drained mainly into the left inferior phrenic vein (③), the gastrorenal shunt was absent. The left internal thoracic vein (④), pericardial phrenic vein (⑤), and left inferior pulmonary vein (⑥, which is from the outflow shunt) were other drainage veins. Mild stenosis is observed between the inferior vena cava and left inferior phrenic vein.
