Pectus Carinatum

Pectus carinatum is a congenital chest wall deformity. It affects the shape and appearance of the chest. This condition, also known as pigeon chest, is characterized by a protruding breastbone that pushes outward from the chest.

Pectus carinatum is a type of thoracic malformation. It develops during childhood and can vary in severity.

For those living with pectus carinatum, the visible protrusion of the breastbone can lead to self-consciousness. It can impact their quality of life. Beyond the cosmetic concerns, this chest wall deformity may also cause physical discomfort.

In some cases, it can affect cardiac and respiratory function. Gaining a deeper understanding of pectus carinatum is key. It is important for patients, families, and healthcare professionals to ensure proper diagnosis, treatment, and support.

In this article, we will explore the causes, symptoms, and various treatment options for individuals with pectus carinatum. By shedding light on this often-misunderstood condition, we aim to empower patients and their loved ones. We want to provide them with the knowledge and resources needed to navigate the challenges associated with this chest wall deformity and improve their overall well-being.

What is Pectus Carinatum?

Pectus carinatum, also known as pigeon chest, is a chest condition where the breastbone and ribs stick out. This makes the chest look like a pigeon’s. It’s caused by the ribs growing too much and pushing the breastbone forward.

This condition happens when the cartilage that connects the ribs to the breastbone grows too much. This pushes the sternum and ribs out, making the chest look like it’s bowing out. Pectus carinatum can be divided into two main types:

Prevalence and Demographics

Pectus carinatum is not very common, affecting about 1 in every 1,500 to 1 in every 1,000 babies. It’s more common in boys than girls, with a 4:1 ratio. The condition often gets worse during puberty, when the body grows fast.

The exact reason for pectus carinatum is not known, but it seems to run in families. About 25% of people with this condition have a family history of similar chest issues.

Causes and Risk Factors of Pectus Carinatum

Understanding the causes and risk factors of pectus carinatum is key for early treatment. The exact cause is not known, but genetic factors and developmental issues are thought to be involved.

Genetic Predisposition

Research shows pectus carinatum often runs in families. This suggests a strong genetic link. People with a family history of chest deformities are more likely to have it. The genetics are complex, involving many genes and environmental factors.

Connective Tissue Disorders

Connective tissue disorders are linked to pectus carinatum. These disorders affect the strength and flexibility of tissues, leading to skeletal issues. Some disorders include:

Other Possible Causes

Genetic and connective tissue disorders are well-known risks. But other factors might also play a role. These include:

• Abnormal growth and development of the costal cartilages
• Imbalances in muscular forces acting on the chest wall
• Hormonal factors, such as during puberty

Having these risk factors doesn’t mean someone will definitely get pectus carinatum. And not having them doesn’t mean it can’t happen. More research is needed to understand how these factors interact.

Symptoms and Complications

The physical symptoms of pectus carinatum vary. The most obvious sign is a “bird-like” chest due to a protruding breastbone and ribs. Some people may also feel chest pain, have trouble breathing, or get tired easily when exercising.

Pectus carinatum can also affect a person’s psychological impact. Many, like adolescents, feel embarrassed about their chest. This can lead to low self-esteem, social anxiety, and a fear of activities that show their chest, like swimming or sports.

In some cases, it can also harm cardiopulmonary function. The changed chest wall might press on the heart and lungs. This can cause:

While these heart and lung problems are not as common as the cosmetic issues, they show why proper treatment is key. It helps avoid long-term health problems.

Diagnosis and Assessment

Diagnosing pectus carinatum requires a detailed diagnostic process. It includes a thorough physical check, advanced imaging studies, and using the Haller index to measure severity. This method helps doctors create a treatment plan that fits each patient’s needs.

Physical Examination

The first step is a physical check. A doctor looks at and touches the chest to see how much it sticks out. They also check the patient’s posture, breathing, and any muscle problems that might be linked to the condition.

Imaging Tests

To understand the chest wall better, doctors might use different imaging tests, such as:

Severity Classification

The Haller index is a key tool for measuring chest wall deformity severity. It’s calculated by comparing the chest’s width to its depth on a CT scan. A higher index means a more severe case, guiding doctors to the best treatment.

Non-Surgical Treatment Options

For those with mild to moderate pectus carinatum, non-surgical treatments can help. These include brace therapy and physiotherapy. Regular check-ups with healthcare providers are also key.

Orthotic Bracing

Orthotic bracing is a common non-surgical treatment. It gently presses on the chest to reshape it. The time needed for this treatment varies, but it’s usually 6 months to 2 years.

The table below shows how often to wear the brace:

Physical Therapy and Exercises

Physiotherapy is often paired with brace therapy. It includes chest exercises, posture training, and breathing techniques. Physical therapists create custom exercise plans for each patient.

Monitoring and Follow-up

Regular check-ups are vital during treatment. Healthcare providers track progress and adjust the treatment as needed. Keeping in touch with your medical team is important for the best results.

Surgical Interventions for Pectus Carinatum

In severe cases of pectus carinatum, surgical treatment is often needed when other methods fail. The Ravitch procedure is the most common surgery. It involves cutting the chest, removing bad cartilage, and moving the sternum.

New minimally invasive techniques are also available. They aim to lessen scars and quicken recovery. The Abramson procedure, for example, uses a special brace to slowly change the chest shape over months.

Choosing between surgery options depends on several factors. These include how severe the deformity is, the patient’s age, and their health. Here’s a comparison of the Ravitch procedure and newer, less invasive methods:

Surgery can fix pectus carinatum, but it comes with risks. These include infection, bleeding, and bad reactions to anesthesia. It’s important for patients to talk to their doctor about the pros and cons of surgery to decide what’s best.

Choosing the Right Treatment Approach

There’s no single way to treat pectus carinatum. The best treatment depends on the patient’s age, how severe the condition is, and what they prefer. By looking at these factors and talking to experts, patients and their families can create a personalized treatment plan. This plan will meet their unique needs.

Factors to Consider

Healthcare providers look at several things to decide the best treatment:

Considering these factors helps doctors suggest the best treatment. This could be orthotic bracing, physical therapy, surgery, or a mix of these.

Consultation with Specialists

It’s key for patients with pectus carinatum to talk to a team of experts. This multidisciplinary care includes pediatric surgeons, orthopedists, and physical therapists. They all know a lot about chest wall deformities.

In these talks, patients and their families can share their worries, ask questions, and learn about the treatments available. They’ll understand the good and bad of each option.

With a caring and knowledgeable healthcare team, patients can feel sure about their treatment choice. They’ll get the care they need to get better and live a better life.

Coping and Support for Patients and Families

Living with pectus carinatum can be tough for patients and their families. The visible chest wall deformity can make them feel self-conscious, anxious, and have low self-esteem. It’s important for those affected to find emotional support and connect with others who get what they’re going through.

Emotional and Psychological Impact

Patients with pectus carinatum face many emotional and psychological challenges. These include:

It’s key to tackle these emotional challenges to improve well-being and quality of life. Professional counseling or therapy can help patients find ways to cope and build strength.

Connecting with others who have pectus carinatum is very helpful. Support groups, both online and in-person, offer a safe place to share experiences and find encouragement. Some great resources include:

• Pectus Carinatum Awareness and Support – A nonprofit organization providing education, patient advocacy, and family resources
• Pectus.com – An online community forum for individuals with pectus deformities to connect and share information
• Children’s Hospital Pectus Program – Many children’s hospitals offer pectus programs with teams to support patients and families

Seeking help from healthcare professionals, like psychologists or social workers, can also be beneficial. They can help patients and families deal with emotional challenges and find the right resources.

Prognosis and Long-term Outcomes

People with pectus carinatum can see great results with the right treatment and care. The success of treatment depends on how severe the condition is and the chosen method. Orthotic bracing, a common non-surgical option, works well, mainly when started early and used regularly.

Surgery, like the Ravitch technique or newer, less invasive methods, also shows great results. These surgeries can reshape the chest and make it look better. Here’s a comparison of treatment success rates:

Successful treatment not only fixes the physical issue but also boosts a person’s quality of life. Many patients feel more confident and comfortable in their bodies. They also enjoy physical activities more after treatment. Keeping up with follow-up care and support is key to keeping these benefits.

Ongoing research aims to make treatments even better. New advancements in bracing and surgery are making life better for those with pectus carinatum. These improvements help people live happier, healthier lives.

Ongoing Research and Future Developments

The field of pectus carinatum treatment is always growing. Researchers and doctors are working hard to find new treatments and better results. They are testing new bracing methods, surgeries, and other therapies in clinical trials.
