Surgical implications of portal venous system malformation Marks CAnn R Coll Surg Engl 1974[Dec]; 55 (6): 299-306The significance of congenital abnormalities in predisposing to portal hypertension and variceal haemorrhage needs to be remembered when these effects manifest in childhood, as portal venography will permit elucidation of the complicated congenital developmental abnormalities underlying the pathological condition and permit rational surgical amelioration.In the presence of portal hypertension the development of a collateral venous circulation may be represented by a hepatopetal or hepatofugal circulatory pattern and will closely parallel the developmental areas where portal and systemic venous circulations meet, being representative of the embryological anastomosis between the vitelloumbilical system and the posterior cardinal system of veins.|Angiography[MESH]|Biliary Tract/blood supply[MESH]|Child[MESH]|Collateral Circulation[MESH]|Congenital Abnormalities/surgery[MESH]|Duodenum/blood supply[MESH]|Esophageal and Gastric Varices/etiology[MESH]|Humans[MESH]|Hypertension, Portal/complications/etiology[MESH]|Infant[MESH]|Infant, Newborn[MESH]|Liver Circulation[MESH]|Portal System/embryology[MESH]|Portal Vein/*abnormalities/embryology[MESH]|Pulmonary Veins/abnormalities[MESH]|Stomach Ulcer/etiology[MESH]|Umbilical Veins/embryology[MESH] |
