Superficial and deep vein thrombosis associated with congenital absence of the infrahepatic
inferior vena cava in a young male patient.
Intravenous heparin (5000 U) to patients with infrahepatic IVC extension before IVC clamping.
Clamps were applied to the opposite (contralateral) renal vein, infrarenal IVC, and infrahepatic IVC in patients with infra hepatic IVC extension.
IVC drains into the Azygos vein (black straight arrow) that enters the thorax together with the aorta (star).
portal vein, hepatic artery and infrahepatic
The donor inferior vena cava (IVC) is typically transected immediately above and below the intrahepatic portions and the supra- and infrahepatic
anastomoses are performed in an end-to-end fashion (Figure 1A).
After hilar dissection and mobilisation of the suprahepatic and infrahepatic
vena cava, the pigs were randomised into two groups: group 1--IP 15 minutes, reperfusion 15 minutes; group 2--no priming (control group).
The involved vessels include the suprahepatic inferior vena cava, infrahepatic
inferior vena cava, portal vein and hepatic artery.
control with clamps is usually adequate for level I thrombus, but mobilization of the liver and temporary occlusion of the portal triad (Pringle manoeuvre) are commonly required for level II and III thrombus.
In this scenario, thrombosis is expected to occur in the ligated infrahepatic
donor IVC and should not be misinterpreted as thrombosis on contrast-enhanced CT.
