OBJECTIVE: To evaluate the sagittal tomographic reformatting of the sternum using unpublished radiographic parameters (indexes and angles), comparing them between the different types of pectus, and controls.
METHODS: 44 patients with pectus deformities and controls underwent chest CT for analysis. The types of pectus were classified into: inferior pectus carinatum (IPC), superior (SPC) and lateral (LPC), and broad (BPE) and localized pectus excavatum (LPE). The following tomographic parameters were created and measured: (1) spine-manubrium-sternum index (SMS); (2) column-sternum index (CSI); (3) manubrium-sternal angle (MSA); (4) inferior manubrium angle (IMA); and (5) inferior sternum angle (ISA). Statistical analysis was performed between the pectus and control groups, and between the different types of pectus.
RESULTS: There was a significant difference between: a) pectus excavatum and pectus carinatum when analyzing the SMS, CSI, MSA and ISA indexes. b) LPE and control group for SMS and ISA. c) LPC and LPE, and LPC and BPE for SMS; d) BPE and LPC for CSI; e) IPC and LPE, and IPC and BPE for ISA; f) SPC and LPE, and SPC and BPE for IMA.
CONCLUSION: The radiographic indexes and angles created provided differentiation parameters between patients with different types of pectus, and between these and controls. Level of Evidence II, Prognostic Studies.
