Summary
Researchers defined the blood supply to the canine cranial sartorius muscle, a single dominant pedicle. This enabled successful transposition of the cranial sartorius muscle flap in dogs for potential hernia repair.
Area of Science:
- Veterinary Anatomy
- Surgical Innovation
Background:
- The cranial sartorius muscle's vascular supply in dogs was not well-defined.
- Understanding this anatomy is crucial for reconstructive surgery.
Purpose of the Study:
- To anatomically define the vascular pedicle of the canine cranial sartorius muscle.
- To assess the feasibility of a cranial sartorius muscle flap for reconstructive surgery in dogs.
Main Methods:
- Anatomical dissection of canine cadavers to identify the vascular pedicle.
- Surgical transposition of the cranial sartorius muscle flap in four dogs based on the identified pedicle.
- Postoperative assessment via gross examination and histological analysis at day 19.
Main Results:
- A single dominant vascular pedicle branching from the femoral artery was identified.
- All four muscle transpositions were successful, showing good adherence and viable muscle tissue.
- Histology confirmed viable skeletal muscle and appropriate tissue healing with mild inflammation.
Conclusions:
- The cranial sartorius muscle flap is a feasible reconstructive option in dogs.
- This technique has potential applications for repairing caudal abdominal and inguinal hernias.
- Further clinical studies are warranted to validate its efficacy.
