Acquired tracheomalacia in a 9-year-old patient with pectus carinatum following modified Abramson technique

Abstract The minimally invasive repair of pectus carinatum (MIRPC) was first introduced by Abramson in 2005. With the increasing popularity and refinement of such technique, the application range has also expanded to include not only the chondrogladiolar type but also the chondromanubrial type. The presence of adequate flexibility in the chest wall has been a prerequisite for applying MIRPC, however, the assessment of sternum flexibility has predominantly relied on subjective compression tests.We report a case of acquired tracheomalacia in a 9-year-old boy with PC following MIRPC, whose chest wall demonstrated slightly increased rigidity while remaining malleable for shaping during the preoperative compression test. The patient's condition improved after treatment and he was subsequently discharged; nevertheless, the entire process of diagnosis and treatment still carries significant cautionary and instructive implications.
