title: Cranial sartorius muscle flap in the dog.
abstract: An anatomic study was performed on canine cadavers to define the blood supply to the cranial sartorius muscle. The vascular supply to this muscle was found to be a single dominant pedicle branching from the femoral artery at the proximal portion of the muscle. This anatomic information was applied in designing a study to determine the feasibility of performing a cranial sartorius muscle flap in the dog. The cranial sartorius muscle was transposed to the caudal abdominal region in four dogs. The muscle flap was based on the singular vascular pedicle defined in the anatomic study. All muscle transpositions were successful on day 19 as evidenced by gross appearance and histologic examination. Grossly, the muscles were well adhered to the recipient sites and were covered by connective tissue. Histologically, the specimens were characterized by viable skeletal muscle fibers, proliferative and maturing granulation and fibrous connective tissue, and mild to moderate mononuclear inflammation. Seroma formation and infection were the two postoperative complications noted. The cranial sartorius muscle flap has potential clinical application for repair of traumatic caudal abdominal hernias and large inguinal hernias in the dog.
