Pectus Arcuatum: Un pectus como ningún otro
Topic overview
Pectus arcuatum is a distinct chest wall deformity caused by premature sternal suture fusion, not abnormal costal cartilage growth like pectus carinatum. This multicenter study of 34 patients shows 35% have associated malformations (Noonan syndrome, scoliosis, cardiac defects) and orthopedic treatment is ineffective—surgical correction via sternotomy is the definitive approach.
Key takeaways
- Pectus arcuatum is distinct from pectus carinatum: caused by premature sternal suture fusion, not abnormal costal cartilage growth.
- Lateral chest X-ray or CT confirms diagnosis by showing sternal fusion; complete fusion present in 75% of imaged cases.
- 35% have associated malformations: Noonan syndrome (33%), scoliosis (25%), or cardiac anomalies (16%)—screen systematically.
- Orthopedic bracing is ineffective for pectus arcuatum, unlike other pectus deformities.
- Surgical correction via sternotomy with partial chondrocostal resection is reserved for post-growth patients seeking repair.
