Vascular Anomaly of the Prescapular Branch of the Superficial Cervical Artery and Vein of an Omocervical Free Skin Flap: A Case Report in a Dog

Summary

This report documents an anomalous blood supply to an omocervical free skin flap in a dog. Consideration of this anomaly should be taken into account when harvesting this skin flap to prevent inadvertent injury to its blood supply.

An omocervical free skin flap, which had an anomalous pathway of its vascular pedicle, was used to cover a full-thickness skin wound on the front limb. This vascular anomaly has not been reported in the dog.
