The sternum of pectus excavatum caves inward and backward, directly compressing the patient's heart or lungs, causing a certain degree of chest pain. This chest pain is not caused by pectus excavatum itself, but by the compression of the heart or lungs due to pectus excavatum. Imagine a normal ribcage as an oval shape; its cross-section is also oval and is a ratio of the patient's left-right diameter, transverse diameter, and anterior-posterior diameter. In normal individuals, this ratio is less than 2.5. In pectus excavatum, since the anterior-posterior diameter is significantly reduced and the sternum is markedly pressed towards the spine, the patient's heart is entirely compressed and deformed. Therefore, the patient's coronary arteries or valves may be squeezed and deformed, resulting in about 60% of pectus excavatum patients experiencing chest pain.

What should be noted for pectus excavatum in daily life?

The biggest difference between children with pectus excavatum and normal children lies in the middle chest bone structure sinking backwards and inward toward the spine, creating a deformity where the front chest and the back compress each other. Naturally, this completely compresses the normal position of the heart and lungs. Therefore, the heart of such children is compressed and deformed, pushing the entire heart to one side. We have encountered clinically cases where there are just a few millimeters of space between the sternum and the spine, leaving no room for the heart, thus completely compressing and pushing it to the left side. Imagine a heart, completely compressed and deformed, where the valves inside cannot function normally. Hence, some children may exhibit insufficiencies in their tricuspid and mitral valves. Therefore, in children with pectus excavatum, their heart is under pressure, their valves deformed, leading to poor cardiac function, and their lung function is also compromised. Since the lungs also need space to expand, lungs that are completely compressed cannot fully relax, resulting in such children having poor cardiac and lung functions, reduced exercise endurance, and since the lungs cannot fully expand, such children are prone to catching colds. Thus, for children with pectus excavatum, it is important to avoid catching colds. Moreover, treating the root cause of the condition, which is pectus excavatum itself, is crucial. Therefore, correcting pectus excavatum early on is essential.

Postoperative complications of pectus excavatum surgery

In theory, if the pectus excavatum surgery is successful, there won't be many long-term complications. However, if we have to discuss possible complications or side effects, they can be categorized as either short-term or long-term. For instance, pectus excavatum itself involves the inward and backward indentation of the sternum, which compresses the patient's heart and lungs. The surgery corrects this by pushing or suspending the indented sternum forward. Due to the alteration in the shape and appearance of the bones, the patient may experience some pain post-surgery, but this pain is bearable and usually subsides within three to five days. Particularly in younger children, who have softer bones, normal activities can often be resumed in just a day or two. However, as age increases and bones become harder, patients may feel pain for about three to five days to a week post-surgery, but typically return to normal after a week. Additionally, there might be complications such as pneumothorax, pleural effusion, or even severe cardiac damage. However, these are generally problems that arise from unsuccessful operations or issues that can be resolved in the short term. Therefore, in the long term or over an extended period, there are generally no lasting side effects from pectus excavatum surgery. If there has to be mention of any, it would be the surgical scars left under the armpits, typically one to two scars each measuring 1 to 2 centimeters.

Does pectus excavatum require surgery?

The decision on whether surgery is needed for pectus excavatum depends on the patient's age, the severity of the deformity, and the elasticity of the chest wall. If the patient is very young, under one year old, and the pectus excavatum is not very severe, we recommend a watchful waiting approach. In patients with pectus excavatum under one year old, it is possible that the condition is pseudopectus excavatum, which may improve as they grow and develop within the first year. However, not everyone improves, with about one third of the cases showing improvement within the first year. If the child is older than one year, the likelihood of improvement is basically none, and at this time, conservative treatment using a pectus excavatum suction cup can be considered. If adhered to effectively, the suction cup can have a certain effect for some patients with pectus excavatum. But if the patient is over three to five years old and the chest wall has matured, surgery should be considered. Therefore, for the vast majority of patients with pectus excavatum, surgery is a relatively definitive and immediately effective method.

Pectus excavatum causes

The etiology of pectus excavatum is not fully clear yet, but it has been found that the incidence of pectus excavatum greatly increases among patients with connective tissue diseases, possibly related to the disruption of the balance between growth genes and inhibitory genes affecting the cartilage on both sides of pectus excavatum. Moreover, it is also found that the complication of pectus excavatum significantly increases among patients with Marfan syndrome (also a type of connective tissue disease) and Noonan syndrome. In children with congenital airway stenosis and bronchopulmonary dysplasia, the incidence of pectus excavatum also significantly increases. This suggests that the causes of pectus excavatum are directly or indirectly related to genetics and heredity, and regardless, the causes of pectus excavatum, both acquired and congenital, are directly related to genes and heredity.

Why can't people with funnel chest gain weight?

In clinical observations, we have found that children with pectus excavatum generally do not have as good nutrition as normal children, and are not as plump. This may be related to the deformity of the chest indentation. We know that the normal cross-section of the thorax on a CT scan is oval-shaped, with the heart and lungs located behind the sternum. In children with pectus excavatum, the sternum is compressed backward toward the spine, which deforms and even pushes the heart completely to one side. This compression of the heart limits the blood's ability to fully return to the heart, and may even prevent the valves from closing completely, leading to valve insufficiency. As a result, both cardiac and pulmonary functions are somewhat impaired. Therefore, 80% of children with pectus excavatum experience exercise intolerance, meaning they cannot run as well as normal children, which also indicates poorer physical fitness and, comparatively, a lesser appetite. Recent studies have found that children with pectus excavatum also have slightly weaker immune functions, and their digestive and absorption capabilities are not as good as those of typical children. Poor exercise capacity and digestive function ultimately lead to poorer nutrition in children with pectus excavatum, making them less plump than normal children.
