[Abnormality of hepatic perfusion secondary to superior vena cava obstruction: three case reports]. / Troubles de la perfusion hépatique secondaires à une thrombose cave supérieure: à propos de trois cas.

The aim of this study was to evaluate the altered flow dynamics of liver perfusion that can be observed during superior vena cava obstruction. Through the description of three case reports of patients with SVC obstruction, the authors discuss the different collateral pathways used that result in systemic portal venous shunting creating this altered flow dynamics and their appearance in computed tomography.
