Background

Umbilical hernias are a relatively common, possibly hereditary, condition in calves. Acellular aortic matrix (AAM) was evaluated for the repair of umbilical hernias in nine calves.

Methods

Fresh buffalo aorta to be used as a graft was decellularised using 1% sodium dodecyl sulfate and 0.25% trypsin. Under xylazine sedation and local analgesia, the hernial ring was exposed and repaired with the AAM graft using an inlay technique.

Results

All animals had an uneventful recovery without clinical signs of wound dehiscence, infection or recurrence of hernias during the 6-month follow-up period.

Conclusion

AAM of buffalo origin has adequate strength to be used safely for the repair of umbilical hernias in calves.
