It’s not about the dent: Anteroposterior Insufficiency in Pectus Excavatum

jpedsurg.org

Pectus Excavatum (PEx) is an anterior chest wall deformity associated with sternal depression. Minimal invasive repair of PEx (MIRPE) and open pectus repair depend on anterior ribs to elevate the sternal defect. Many PEx patients, however, have inadequate anteroposterior (AP) distance to support a complete repair. The quantity and frequency of AP insufficiency (API) in a PEx surgical population is reported.

In brief

This article examines anteroposterior insufficiency in pectus excavatum patients undergoing surgical repair. It reports on the prevalence of inadequate AP chest distance that can compromise both minimally invasive and open repair techniques, highlighting a critical anatomical consideration for surgical planning.

Pectus excavatum repair relies on anterior ribs to elevate the sternum, but many patients lack adequate anteroposterior chest distance.
Anteroposterior insufficiency is a common anatomical limitation in pectus excavatum patients that can compromise surgical outcomes.
Both MIRPE and open repair techniques depend on sufficient AP distance; inadequate distance may require modified surgical approaches.
Preoperative assessment of AP chest dimensions is critical for surgical planning in pectus excavatum correction.
