VASUK
“Banking on your horses chance of optimised healing of tendon, ligament and joint injuries”
The idea of VAS UK came about when Chance X, a much loved and very successful grassroots event horse, sustained a potentially career ending stifle injury. Through a combination of careful diagnosis, arthroscopic surgery, intra articular medical and regenerative therapy, rehabilitation and physiothe
rapy - Chance X was able to return to his eventing career and provide ongoing success and happiness to his teenage rider and supporters. His owner, Jenny Walton http://linkedin.com/in/jen-walton-3b64a234 a veterinary surgeon herself, who has a long background in veterinary blood banking founded VAS UK whilst studying for her masters in lyophilized platelet use in dogs. Dr Anne Hale http://linkedin.com/in/anne-hale-27696146 veterinary surgeon, Jenny’s mentor and sponsor for the masters - provided 30yrs of expertise in veterinary apheresis, transfusion medicine and regenerative medicine to assist in developing the programme. An injection of platelet rich plasma (prp) was used in Chance’s therapy but Jenny and Anne felt that there was a way to improve how this was sourced and utilised, due to their knowledge of apheresis technology. The consideration that prp could also be stored as lysate if collected in appropriate quantities, allowed the idea of an individual horses “bank” of multiple regenerative injections to be collected during one event from that horse that could be used over the coming months/years. Apheresis allows the collection of an autologous, increased and more reliable concentration (compared to most low volume whole blood filtration and centrifugation methods), red cell white cell- reduced, aseptically prepared platelet product. In a 45min event around 200ml of PRP is collected from an individual horse. Post collection, a specially designed separation system developed by veterinary and human blood bankers (Innovative animal supplies - IAS) allows the sterile preparation of 15 aliquot doses of 10-25ml. Quantities can be tailored to the treating vets requirement. A prp injection can be used immediately intra-lesion (such as a tendon tear) or into the joint of an injured horse. The additional aliquots are frozen between -20/80°c for 2-5yrs depending on storage conditions and the injury being managed. Freezing results in the PRP becoming equine platelet lysate which contains the platelet proteome (content) which is considered beneficial in creating the healing environment that we look for in regenerative medicine. With injury injections in horses standardly being between 4-10ml, this process allows at least 15 separate treatments per horse.
