pectus excavatum

Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.


pectus carina´tum a malformation of the chest wall in which the sternum is abnormally prominent. Moderate cases cause no difficulties and require no treatment; in severe cases the deformity may interfere with lung and heart action, causing dyspnea on exercise and increased susceptibility to respiratory infections. Serious malformations can usually be corrected by surgery. Called also pigeon breast or chest and chicken breast.
pectus excava´tum a congenital malformation of the chest wall characterized by a funnel-shaped depression with its apex over the lower end of the sternum; it is caused by shortening of the central portion of the diaphragm, which pulls the sternum backward during inhalation, and by the growth of ribs. Except in mild cases, it decreases the ability of the child to engage in sustained exercise. It also delays recovery from coughs and colds, reduces the ability to eat a full meal (so that most patients are underweight), and often produces a functional heart murmur. Noisy breathing may occur during sleep. A child may develop an emotional problem because of embarrassment over the deformity. It can be satisfactorily corrected by surgery. Called also funnel breast or chest and koilosternia.

Another drawback of note is that we focused solely on pectus excavatum and failed to include mixed deformities.
PE pushes the heart to the left, with the transformation of the ribs and costa cartilages; the internal counter force generated by the heart will push the thoracic vertebrae to the right, which means the heart may provide an asymmetric horizontal force to push the spines to the right in pectus excavatum patients with scoliosis.
Many pathologies like various clinical cases including chest wall deformities (pectus excavatum, oesophagus diseases, adenoid cystic) can accompany tracheal bronchus.2
Mum Sarah Grierson explained that because Autumn's chest condition - pectus excavatum - pushes her ribs inward, leaving a gap big enough for a tennis ball, it can cause pressure on her lungs and make breathing more difficult.
Other congenital abnormalities include cardiac defects in 36% of affected boys [8] and skeletal problems such as pectus excavatum, scoliosis and vertebral abnormalities.
