Distinguish funnel chest by clinical symptoms and signs, as well as imaging manifestations.
1. Clinical symptoms: patients often manifest angina pectoris, myocardial ischemia or arrhythmia, accompanied by symptoms such as chest tightness or shortness of breath, which indicates that the lungs are being compressed, and these are the clinical manifestations of funnel chest.
2. Physical signs: Visual examination of funnel chest reveals obvious inward concave deformity of the thorax, anterior extension of the shoulders, a slight hunchback deformity, and there may also be epigastric protrusion and other physical signs.
3. Imaging manifestations: chest X-ray can see the chest concave, through the CT can see obvious deformity and mediastinal displacement, can use the thoracic index, that is, the ratio of the largest transverse diameter of the chest to the narrowest anterior-posterior diameter to assess the severity of funnel chest.
When funnel chest is present, it is important to go to the hospital in time and be treated actively under the guidance of the doctor.
