Direct percutaneous access to a mesenteric vein for antegrade embolization of esophageal varices: A case report.

A 79-year-old woman with a history of advanced gastric cancer and portal vein tumor thrombus, treated with surgery and chemoradiotherapy, presented with hematemesis due to esophageal variceal bleeding around the esophagojejunal anastomosis. Endoscopic treatment was unsuccessful. Due to portal vein occlusion, percutaneous transhepatic access was difficult. Thus, the middle colic vein, which was dilated due to portal vein occlusion, was percutaneously punctured, and antegrade embolization of a jejunal vein feeding the varices was performed using a microcatheter through a 4-F dilator placed as a sheath. After embolization, the sheath was removed, and ultrasound-guided compression of the puncture site was performed. No bleeding complication occurred. Therefore, direct percutaneous access to a mesenteric vein is a viable alternative to transhepatic access.
