Using acellular aortic matrix to repair umbilical hernias of calves.

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.
