The sartorius muscle flap in the cat: an anatomic study and two case reports.

Abstract

The sartorius muscle in the cat is a broad, sheet-like muscle which covers the craniomedial aspect of the thigh. The major portion of the blood supply arises from the proximal pole of the muscle. A single sartorius muscle can be positioned over the abdomen in a transverse manner along the pubis, to cover the entire (i.e., left and right sides) caudal 30% of the abdomen. It also can be extended in a cranial-to-caudal fashion where it covers approximately 80% of the length and 75% of the width of the ipsilateral abdomen. The sartorius muscle flap is easy to harvest and provides good coverage for defects of the caudal abdominal wall. This muscle flap was used successfully in two feline patients.
