title: Portal venous collateral drainage in IVC obstruction.
abstract: Collateral venous drainage via the portal venous system has been demonstrated in three patients with testicular teratoma and IVC obstruction using contrast venography and enhanced computed tomography (CT). The use of CT in assessing the extent of the collateral circulation in IVC obstruction together with implications for surgical management are discussed.
