Función sensorial a largo plazo, 3 años después de la reparación mínimamente invasiva del Pectus Excavatum Con Crioablación
Topic overview
Three-year follow-up study of 47 patients after minimally invasive pectus excavatum repair with intercostal nerve cryoablation found 46.8% had identifiable chest wall hypoesthesia affecting a median 4-6% of anterior chest wall surface area. Neuropathic symptoms occurred in 13% of patients but required no treatment.
Key takeaways
- 46.8% of patients had identifiable chest wall hypoesthesia 3 years post-MIRPE with cryoablation, affecting only 4-6% of treated surface area
- Hypoesthesia was limited to 1-2 dermatomes in most cases, most commonly T5, suggesting focal rather than diffuse sensory changes
- Chronic symptomatic neuropathic pain was rare (13% reported symptoms, none required treatment) despite nearly half having sensory changes
- Long-term sensory recovery appears favorable: majority (62%) had no hypoesthesia to cold in any dermatome at mean 2.9 years follow-up
