Volumetric study of tracheal diverticulum: a retrospective analysis in computed tomography

Aim: The aim of this study was to retrospectively evaluate the prevalence and morphology (location, diameter, number volume) tracheal diverticulum (TD) on thoracic computed tomography (CT), in a sample Turkish population.
 Material Method: conducted over 15 months, from February 2020 April 2021, included 3,860 CT scans, which 1,891 subjects were men rest women. All scans evaluated retrospectively. images reviewed for presence or absence TD axial plane, defined as air sacs around trachea communication with trachea. For volume measurement, contour manually by single radiologist, all patients. Descriptive statistics reported mean±standard deviation (SD). A p value less than 0.05 considered significant.
 Results: mean age patients 57.87±14.76 (29-84). In study, incidence calculated be 0.80%. (TDV) maximum transverse diameter (MTD) 983.62±1 509.80 mm3 8.79±6.19 mm, respectively. 
 Conclusion: we demonstrated volumetric measurement its prevalence. We believe that frequency use clinical practice should increase, measurements provide healthier results measurements.
