Pectus Excavatum: Symptoms and Causes

Spread the love

Pectus Excavatum Symptoms: Pectus excavatum, commonly referred to as sunken chest or funnel chest, is a congenital deformity characterized by a concave appearance of the breastbone (sternum).

This condition, which can be noticeable from birth or develop during adolescence, affects approximately 1 in every 400 to 1,000 births, making it the most common congenital chest wall deformity.

Understanding the symptoms and causes of pectus excavatum is essential for early diagnosis and management.

Understanding Pectus Excavatum

Pectus excavatum, often referred to as “sunken chest” or “funnel chest,” is a condition characterized by a concave, inwardly sunken appearance of the breastbone (sternum). This congenital deformity, where the cartilage connecting the ribs to the sternum grows abnormally, causes the chest cavity to appear hollowed out. Understanding the severity and variations in appearance is crucial for recognizing and managing this condition effectively.

Severity and Variations in Appearance

The severity of pectus excavatum can vary widely from mild to severe cases:

  • Mild Cases: In mild forms of pectus excavatum, the depression in the chest is less noticeable and often does not lead to any physical complications or symptoms.
  • Moderate Cases: These are more apparent to the naked eye and might cause some discomfort during physical activities.
  • Severe Cases: In severe instances, the chest indentation can significantly impact the heart and lungs, leading to respiratory difficulties and reduced cardiac efficiency.

The visual appearance of pectus excavatum can also differ substantially between individuals. The depth, width, and overall shape of the chest indentation are unique to each person, making each case distinct.

Differentiating Pectus Excavatum from Other Chest Wall Deformities

Pectus excavatum is just one type of chest wall deformity. Understanding how it differs from others is important for accurate diagnosis and treatment. Here are some other common deformities:

  • Pectus Carinatum: Often called “pigeon chest,” pectus carinatum is the opposite of pectus excavatum. Instead of a sunken sternum, the chest protrudes outward.
  • Poland Syndrome: This is a rare birth defect characterized by the underdevelopment of the chest muscle on one side of the body. It can sometimes include webbing of the fingers on the affected side.
  • Rib Flare: In this condition, the lower ribs protrude abnormally which can be confused with the lower portion of pectus excavatum. However, rib flare does not involve the sternum’s indentation.

However, recognizing these differences is crucial for healthcare providers to formulate appropriate treatment plans and for individuals to understand their own medical condition better.

Symptoms of Pectus Excavatum

Here’s a detailed look at the symptoms associated with pectus excavatum, its psychological and social effects, and how symptoms might change with age or during puberty.

Common Symptoms of Pectus Excavatum

The primary symptom of pectus excavatum is the visible depression in the center of the chest, which can vary in severity. However, several other physical symptoms are commonly associated with the condition:

  • Shortness of Breath: Individuals may experience difficulties breathing, especially during exercise.
  • Chest Pain: Discomfort or pain in the chest area is a common symptom.
  • Fatigue: There may be increased tiredness, particularly after physical activity.
  • Heart Palpitations: Some people might notice their heart feels like it’s skipping a beat or beating too hard.
  • Reduced Exercise Tolerance: The ability to perform physical activities can be less than that of peers, due to cardiovascular limitations.
Psychological and Social Impact

The appearance of the chest can significantly affect psychological and social well-being, particularly in younger individuals:

  • Self-Esteem Issues: The noticeable deformity can lead to feelings of self-consciousness and embarrassment.
  • Social Withdrawal: Children and teenagers with pectus excavatum may avoid activities that involve exposing their chest, such as swimming or gym class.
  • Body Image Concerns: Persistent worries about physical appearance can lead to long-term body image issues.
Changes in Symptoms With Age or During Puberty

The symptoms of pectus excavatum can evolve as an individual ages, particularly during the puberty growth spurt:

  • Increased Severity of Chest Deformity: As children grow rapidly during puberty, the depression in the chest can become more pronounced.
  • Worsening of Respiratory Symptoms: Respiratory functions may decline with the deepening of the chest pit.
  • Increased Physical Symptoms: Symptoms such as fatigue and chest pain may intensify as the body grows.

However, early intervention and treatment can help manage the physical discomforts and psychological impacts, enhancing quality of life and overall health outcomes.

Causes and Risk Factors of Pectus Excavatum

Here we’ll explore the various causes, associated risk factors, and the prevailing theories related to the growth abnormalities of the ribs and sternum that contribute to this condition.

Causes of Pectus Excavatum

The exact cause of pectus excavatum is not fully understood, but it is believed to result from abnormal growth of the cartilage that connects the ribs to the sternum. This abnormal growth causes the sternum to move inward, creating a depression in the chest. The condition is typically present at birth (congenital), suggesting that it may develop during fetal development. However, it can become more pronounced during adolescence when rapid growth spurts occur. Key causes include:

  1. Genetic Factors: There is often a family history suggesting a genetic predisposition. Studies have found that pectus excavatum may run in families, indicating possible genetic causes.
  2. Connective Tissue Disorders: Some individuals with pectus excavatum have an underlying connective tissue disorder such as Marfan syndrome or Ehlers-Danlos syndrome, which can affect the strength and elasticity of the cartilage.
  3. Congenital Structural Anomalies: In some cases, pectus excavatum is associated with congenital structural anomalies in the chest wall during fetal development.
Risk Factors of Pectus Excavatum

Certain factors may increase the likelihood of developing pectus excavatum:

  1. Family History: Having a parent or sibling with pectus excavatum significantly increases the risk.
  2. Gender: Males are more frequently affected than females, with estimates suggesting about a 3:1 ratio.
  3. Growth Spurts: Rapid growth during puberty can exacerbate the condition as the chest wall may not grow evenly.
  4. Other Medical Conditions: Associated conditions like scoliosis, asthma, and respiratory infections can also be risk factors due to their impact on chest wall development.
Theories and Studies on Rib and Sternum Growth

Research into the growth of the ribs and sternum provides insights into the development of pectus excavatum. Key theories include:

  • Excessive Growth of Costal Cartilage: The most widely accepted theory suggests that excessive growth of the costal cartilage causes the sternum to be pushed inward, leading to the characteristic depression.
  • Imbalance in Muscle Development: Some researchers propose that an imbalance in the development of the muscles that attach to the sternum and ribs might contribute to the inward growth of the sternum.
  • Genetic Mutations: Recent studies have focused on identifying specific genetic mutations that could affect the development of the chest wall, offering potential targets for genetic testing and intervention.

However, ongoing research continues to shed light on the complexities of this condition, promising better treatment approaches in the future.

Diagnosing Pectus Excavatum

Here we outline the common diagnostic procedures, criteria for diagnosing based on symptoms and visual assessments, and the importance of early diagnosis and monitoring progress over time.

Common Diagnostic Procedures

1. Physical Examination: The first step in diagnosing pectus excavatum typically involves a thorough physical exam where a doctor observes the chest’s shape.

2. Medical History: A detailed medical history helps to identify any genetic patterns or early developmental issues that may contribute to the condition.

3. Imaging Tests:

    • Chest X-ray: Helps in assessing the severity of the chest depression.
    • CT Scan: Provides detailed images of the bones and measures the severity of the chest’s indentation using the Haller index, a quantitative metric.
    • MRI: Occasionally used to assess the impact on surrounding organs and to plan for surgical procedures if needed.

    4. Pulmonary Function Tests: These tests assess how well the lungs are working, determining if the condition affects breathing.

    5. Echocardiogram: Used to check heart function, particularly if the patient has symptoms like chest pain or palpitations.

      Criteria for Diagnosis Based on Symptoms and Visual Assessments

      The diagnosis of pectus excavatum often includes evaluating specific symptoms and conducting visual assessments:

      • Visual Signs: Noticeable recession of the chest wall, especially noticeable during inhalation.
      • Symptomatic Evaluation: Symptoms such as shortness of breath during exercise, fatigue, chest pain, and heart palpitations are significant indicators.
      • Physical Impact: Assessing any physical discomfort or psychological impact due to the appearance of the chest.
      • Severity Assessment: The severity is often measured by the degree of chest depression and its impact on cardiac and respiratory functions.
      Importance of Early Diagnosis and Monitoring Progress Over Time

      Early diagnosis of pectus excavatum is crucial for several reasons:

      • Preventive Care: Early detection can help manage symptoms and prevent complications associated with heart and lung function.

      Non-surgical options are typically recommended for milder cases of pectus excavatum or for individuals who prefer less invasive approaches:

      1. Physical Therapy: Specialized exercises can strengthen the chest muscles and improve posture, potentially reducing the depth of the chest concavity.
      2. Vacuum Bell Therapy: This involves using a suction device that the patient applies over the chest. The vacuum bell helps to pull the sternum outward, promoting a more normal chest appearance. Continuous use over several months to years is often required for noticeable improvement.
      3. Breathing Exercises and Techniques: Respiratory therapies can help improve lung capacity and endurance, aiding overall chest function.
      4. Orthotic Bracing: Similar to braces used in spinal conditions, orthotic devices can be customized to apply pressure externally on the chest wall, encouraging the sternum to move outward.
      Surgical Options and Advancements in Treatment

      Surgical intervention may be considered for more pronounced cases of pectus excavatum or when non-surgical treatments fail to achieve desired results:

      1. Nuss Procedure: A minimally invasive technique where curved metal bars are inserted behind the sternum, flipping them to push the sternum outwards. The bars are usually removed after a few years.
      2. Ravitch Technique: An older and more invasive method than the Nuss procedure, this surgery involves removing the cartilage that causes the sternum to grow inward and then reconstructing the affected area with support structures.
      3. Robotic Surgery: Emerging advancements in robotic technology allow for more precise and less invasive corrections of the chest wall.
      4. Customized Implants: For cases where standard procedures are not viable, patient-specific implants made from biocompatible materials can be designed to correct the chest deformity.
      Importance of Personalized Treatment Plans

      Every individual with pectus excavatum presents a unique set of challenges and conditions, making personalized treatment plans essential. Factors to consider include:

      • Age and Growth: Treatment timing can significantly impact outcomes, especially in younger patients whose bones are still growing.
      • Severity of Deformity: The depth and extent of the chest concavity often determine the choice between surgical and non-surgical treatments.
      • Overall Health and Medical History: Existing health issues can influence both the feasibility and type of treatment.
      • Patient Preferences and Lifestyle: Personal preferences, lifestyle, and the patient’s psychological readiness play crucial roles in treatment choice and success.

      However, a multidisciplinary approach involving pediatric surgeons, pulmonologists, cardiologists, and physical therapists is often necessary to effectively address the complexities of pectus excavatum.
