Summary An acellular aortic matrix ( AAM ) crosslinked with 1‐ethyl‐3‐3‐dimethylaminopropylcarbodiimide hydrochloride ( EDC ) was evaluated for the repair of inguinal hernias in 5 horses. The aorta from buffalo was acellularised using 1% sodium dodecyl sulfate ( SDS ) and 0.25% trypsin. The AAM was crosslinked with 1% EDC . Under anaesthesia, inguinal hernias were repaired with EDC ‐crosslinked AAM graft using an inlay graft technique. Blood samples collected on Days 0, 15 and 30 post implantation, were used for SDS polyacrylamide gel electrophoresis ( PAGE ) analysis to assess the animals' serum protein concentration, and gelatin zymography for the identification of matrix metalloproteinases. All animals that underwent hernia repair demonstrated successful healing without clinical signs of wound dehiscence, infection or recurrence during a 6‐month follow‐up period. SDS‐PAGE analysis of serum protein concentrations revealed that, this was increased at Day 15 and had decreased again at Day 30. Gelatin zymography of serum of implanted horses expressed a band of 92 k D a, corresponding to MMP ‐9 activity. The relative amount of the 92 k D a band was higher at Day 15 as compared to Days 0 and 30. It may be concluded that EDC ‐crosslinked AAM of buffalo origin can be used safely in horses for the repair of inguinal hernia with adequate strength and minimal foreign body reaction.
