Active venovenous bypass of the retrohepatic vena cava utilizing two atrial cannulae.
Injuries to the hepatic veins and retrohepatic vena cava have a high mortality due to uncontrolled hemorrhage. Successful repair may necessitate interruption of flow through the retrohepatic vena cava. Active bypass of the area is then needed to provide adequate venous return. Published methods for active bypass require cannulation of axillary and femoral veins in addition to clamping of the vena cava above and below the liver, often with limited exposure and significant risk. This report describes active bypass of the retrohepatic vena cava utilizing two right atrial cannulae. The simplicity of establishing the bypass together with the excellent exposure allowed repair of a bullet wound of the vena cava in one patient and the orderly performance of a left trisegmentectomy for a huge hepatic tumor in a second patient.
