Q67.6

Clinical Causes: Genetic factors: Many cases are inherited, with a family history suggesting a genetic predisposition. Connective tissue disorders: Conditions such as Marfan syndrome or Ehlers-Danlos syndrome are associated with chest wall deformities. Abnormal development: During fetal development, improper formation of the cartilage connecting the ribs and sternum can lead to pectus excavatum.

Key Symptoms: Visible sunken appearance of the chest, often asymmetrical in some cases Physical discomfort, including chest pain or tenderness Shortness of breath during physical activity Rapid heartbeat or palpitations in more severe cases Fatigue during exertion In some cases, psychological effects such as self-consciousness or low self-esteem due to chest appearance

Diagnosis Path: Diagnosis typically involves a physical examination by a healthcare provider, who assesses the chest's shape and may order imaging studies such as chest X-rays, computed tomography (CT) scans, or magnetic resonance imaging (MRI). These imaging modalities help determine the severity of the deformity and its impact on the heart and lungs. Pulmonary function tests might also be performed to evaluate respiratory capacity, particularly if symptoms are present. The severity of pectus excavatum is often classified based on the depth of the depression and its effect on organ function.

Treatment Protocols: Treatment options depend on the severity of the condition and associated symptoms. Mild cases that cause no functional issues may require only regular monitoring. For more pronounced or symptomatic cases, intervention may include: - **Surgical Procedures**: The Nuss procedure involves inserting a concave steel bar under the sternum to elevate the chest wall, typically performed minimally invasively. The Ravitch procedure is a more traditional surgery that involves removing cartilage and repositioning the sternum. - **Non-surgical interventions**: Physical therapy and exercises aimed at improving posture and chest expansion may be beneficial in mild cases. - **Psychological support**: Counseling might be helpful for individuals experiencing self-esteem issues related to their chest appearance. Following treatment, patients usually require follow-up assessments to monitor healing and ensure that chest shape and function improve.
