Objective:
To assess what degree of chest wall deformation changes statistically reliably after surgery, using pre- and postoperative radiological examination data.
Methods:
Radiological chest examinations were performed for 88 children before and after remedial operations. Pre- and postoperative chest radiograph and CT were performed to measure transversal chest width; sagittal left chest side depth, sagittal right chest side depth, sternovertebral distance and vertebral body length. Derivative indices were also estimated: Vertebral index (VI), Frontosagittal index (FI), Haller index (HI) and asymmetry index. Computerized assessment of data was used. For statistical analysis, the software "Statistica 6.0" was used.
Results:
Postoperatively VI increased approximately by 2.37+/-2.72, FI decreased by 4.60+/-4.34 and HI value increased approximately up by 0.45+/-0.49. Statistically significant deformation index difference before and after surgery was not detected when VI was below 26.2 (p=0.08), FI was above 32.9 (p=0.079) and HI was less than 3.12 (p=0.098).
Conclusion:
Preoperative CT and X-ray assessment of chest wall deformation degree is important for pediatric patients. The following deformation indices are indications for surgical treatment: VI>26, FSI< 33 and HI>3.1.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
