Pectus carinatum is a chest wall deformity that occurs less frequently. Anaesthesia in such patients may be complicated by associated systemic disorders such as Marfan^,s disease, homocystinuria, Prune belly syndrome, Morquio syndrome, Osteogenesis imperfecta, Noonans syndrome, mitral valve prolapse, scoliosis or other collagen vascular diseases. Though pectus carinatum is widely reported, the literature on anaesthetic management is sparse.
