Glutaraldehyde-fixed heterologous pericardium for vena cava grafting following hepatectomy.
OBJECTIVE
Glutaraldehyde-fixed heterologous pericardium has been widely used for grafts in cardiac surgery. We applied it for inferior vena cava (IVC) patch grafting following combined resection of the liver and the IVC.


METHODS
IVC grafting using a glutaraldehyde-fixed horse pericardium following combined resection of the liver and the IVC was performed in 2 patients--one with hepatocellular carcinoma and the other with hepatic metastasis following rectal cancer. The retrohepatic vena cava defect was closed with a 10 x 5 cm patch in one patient and a 7 x 4 cm patch in the other.


RESULTS
Hepatic vascular exclusion was avoided in both patients. The IVC exclusion period was 40 min for the first patient and 25 min for the second. One patient required a veno-venous bypass with an active centrifugal pump of 153 min. There was no complication and no graft infection. The microscopic extension to the IVC was evident in one patient, and fibrous adhesive was evident in the IVC wall of the other. One patient died of hepatic failure 3 years and 6 months after surgery, and the other died of hepatic recurrence 7 months after surgery. Both grafts were patent, without calcification and stricture, until the patients' death.


CONCLUSIONS
Glutaraldehyde-fixed heterologous pericardium is an option for IVC grafting.
