Measurement of Main Bronchi Longitudinal Diameter in Sudanese Population Using Computed Tomography

Abstract

This study was carried out from September to November 2015 in Khartoum state (Elribat University Hospital, Alamal Diagnostic Center and Antalya Medical Center). The aim of this study to measure main bronchi longitudinal diameter in Sudanese population by using CT The measurement was done from 50 cases there age ranged between 20 to 90 years all these patients under go CT chest scan and there chest was normal from any disease. From 50 cases there are 23 males and 27 females,and study exclude any case with Any musculoskeletal deformity. Kyphoscoliosis, Destructive lung pathologies including fibrosis, bullas, retractions, Meditational and/or extra-bronchial masses compressing large Tracheoomegaly, Tracheomalacia, Bronchiectasis Chronic tuberculosis, Any history of laryngo-tracheal intubation for more than 3 days. The measurement was done by TOSHIBA 64 - 8 slices and NeuViz 16-slice machines. From CT image the author measure the two main bronchi longitudinal diameter and collect the age of cases. The data analysis was done by SPSS program to find out the mean, stander deviation and variance. This study concludes the mean diameter of right main bronchus in Sudanese population is 12.37 ± 1.7 mm and the mean diameter for left main bronchus 11.92 ± 1.4 mm. And to find out the range of normal measurement other 10 patients with pathology in their chest were measured and the study found the range of normality is very narrow because the normal measure is close to abnormal. The study found the asthma narrowing the air way tree. The Atelectasis dilates the two main bronchus; The Emphysema dilates the two main bronchus. The study found the increase of age my increase of diameter of two main bronchi. The study concludes that the Sudanese people have diameter for right and left main bronchus close to Persian. This study recommends further study in measurements of main bronchi and air tree with large sample of population. Study recommends further study done to prove if there was relation between increase of diameter of two main bronchi and age.
