thoracic insufficiency syndrome
Also written as: TIS — Thoracic Insufficiency Syndrome
A condition where chest wall deformity compromises lung growth and respiratory function, often associated with early-onset scoliosis.
Full Definition
Thoracic insufficiency syndrome (TIS) is a clinical condition characterized by the inability of the thoracic cage to support normal respiration or lung growth. This syndrome commonly occurs in children with severe early-onset scoliosis, congenital spine deformities, or chest wall abnormalities that restrict normal thoracic development. The condition results from the complex relationship between spinal deformity, rib cage abnormalities, and lung development during critical growth periods. Patients may present with decreased pulmonary function, exercise intolerance, recurrent respiratory infections, and failure to thrive. Early recognition and intervention are crucial to prevent irreversible pulmonary compromise. Treatment focuses on restoring chest wall stability and allowing normal lung growth through various surgical approaches including growth-friendly instrumentation and chest wall reconstruction.
Usage
Usage note: Always assess and document pulmonary function when this condition is suspected or diagnosed.
