Electronic linear scanning, Portal hypertension, Cruveilhier-Baumgarten type collateral vein, Microscopic view of the liver
We reported a case of a giant collateral vein, which is so-called Cruveilhier-Baumgarten type collateral vein. A case is a 20 year-old man who felt abdominal tumor in his left hypochondrium.
We examined abdominal echography at the beginning. We found that the giant collateral vein continued from the umbilical portion of the left main branch of the portal vein.
In other examinations, angiography showed the giant collateral vein back to the IVC. Liver biopsy showed almost normal. From the above, we diagnosed idiopathic portal hypertension. The patient was performed splenectomy, proximal gastrectomy and devascularization. We made sure of the Cruveilhier-Baumgarten type collateral vein at the operation.
We consider that it would be useful to use abdominal echography in order to find outcollateral vein of portal hypertension, to follow up whether the veins are opened or closed, and also to discover new collateral veins.
