Mixed chest wall deformities- Pectus Arcuatum- horse shoe pectus

Horseshoe chest and mixed deformities

 Although less common than "isolated" chest malformation, mixed types are the most difficult forms to diagnose and treat. Mixed chest abnormalities are usually a combination of both pectus excavatum and protrusion.

​

What is Pectus Arcuatum?

Pectus arcuatum is a rare chest wall deformity that combines features of both:

• Pectus carinatum (protruding chest)

• Pectus excavatum (sunken chest)

In this condition, the upper part of the sternum appears protruded, while the lower part shows depression, resulting in an irregular chest contour.

It is sometimes referred to as a mixed chest wall deformity.

What causes Pectus Arcuatum?

The exact cause is not fully understood, but it is usually related to:

• Abnormal growth of costal cartilage

• Developmental imbalance of the chest wall

• Possible genetic predisposition

The deformity typically becomes more noticeable during adolescence and growth spurts.

What are the symptoms?

Many patients present with mainly cosmetic concerns, but symptoms may include:

• Visible chest asymmetry

• Mild chest discomfort

• Shortness of breath during exertion (in severe cases)

• Psychological impact (low self-confidence, social anxiety)

How is Pectus Arcuatum diagnosed?

Diagnosis is usually based on:

• Clinical examination

• CT scan of the chest to assess severity and structure

• Occasionally lung and cardiac function tests

Is Pectus Arcuatum dangerous?

In most cases, it does not significantly affect heart or lung function.

However, in more severe deformities, it may cause:

• Reduced exercise tolerance

• Compression effects on the chest cavity

• Significant psychological distress

Treatment of Pectus Arcuatum

Treatment depends on:

• Age of the patient

• Severity of deformity

• Presence of symptoms

Non-surgical treatment

In mild cases, external bracing may be considered.
However, its effectiveness is limited compared to isolated pectus carinatum.

Surgical treatment

Surgery is the most effective treatment for moderate to severe cases.

Surgical options include:

• Modified Ravitch procedure (open correction)

• Customized surgical techniques depending on the deformity pattern

Because this condition is a combination of deformities, it requires a tailored surgical approach for each patient.

Recovery after surgery

• Hospital stay: 2–4 days

• Return to normal activity: within 2–4 weeks

• Immediate improvement in chest shape
