Repair of pectus excavatum by percutaneous suturing and temporary external coaptation in a kitten.

Severe pectus excavatum sternal deformity in a 3-month-old kitten was repaired by use of percutaneous circumcostal and circumsternal sutures to coapt the sternal deformity to an external splint made from thermoplastic material. One year after treatment, the kitten remained free of clinical signs of the disease or complications from the repair. The technique represents a conservative method of repair of pectus excavatum deformities in immature animals.
