On initial presentation both cats were dyspneic exercise intolerant and had marked concave deformation of the caudal sternum. Surgical correction of pectus excavatum was performed using a cylindrical external splint and U-shaped external splint. Post-operative thoracic radiography revealed that there was decreased concavity of the sternum and increased thoracic height at the level of the caudal sternebrae in both cats. Keywords cat external splint pectus excavatum surgical correction Pectus excavatum or funnel chest is an uncommon congenital anomaly of the chest wall characterized by the dorsal deviation of the caudal sternum and associated costal cartilages or a ventral to dorsal narrowing of the entire thorax 3 . This defect has been reported in both dogs and cats and can usually be diagnosed within the first few days following birth 2 . Abnormal alignment of the sternum and costal cartilages are responsible for compressive cardiopulmonary dysfunction resulting in exercise intolerance tachypnea cyanosis cardiac murmur arrhythmias or respiratory distress 3 7 . Pectus excavatum-associated cardiopulmonary dysfunction may be life threatening. Several surgical techniques for repair of pectus excavatum have been described in dogs and cats. The use of U-shaped external splint X-Lite classic splint EBI Biomet USA has not been previously .
