Purpose
Equine limb perfusion is a procedure used to treat infections deep within the hoof or other structures of the distal limb. Infections of the distal limb in a horse can pose career ending, if not life threatening, complications if not treated in a timely manner. Systemic administration of antibiotic agents are often not successful because the level of agent in the tissues of the limb cannot reach therapeutic levels. Regional perfusion delivers a high local concentration of antibiotic right where it is needed, and confines it to the affected limb where it can permeate all the surrounding tissues with a therapeutic dose, providing a rapid eradication of the infection before it does permanent damage to delicate structures within the limb. The procedure is broken down into three steps and illustrated with associated key anatomical structures to explain how the procedure works.
You are viewing Step 1 – This is an illustration of a hoof puncture wound. These types of injuries are complicated to treat because they are contained within the hoof capsule. There are many structures which are involved, all in close proximity to each other. Within this tightly confined space and any inflammation of soft tissues can lead to impaired blood flow, and an inability to treat systemically with antibiotics.
View Step 2 – which illustrates how the limb is prepped for the perfusion procedure.
View Step 3 – which illustrates how the therapeutic dose permeates from the blood vessels into the surrounding tissues.
