Venovenous Bypass for Major Hepatic and Caval Trauma

Abstract

Severe trauma to the liver and juxtahepatic cava require vascular isolation of the lesion. In addition to the techniques of vascular clamping and atriocaval shunting, venovenous bypass is a viable alternative to repair such injuries. We herein report its use in five consecutive patients. The technique obviates the hemodynamic sequelae of uncompensated caval occlusion and the technical dangers of atriocaval shunting.
