2017
This is a cross sectional descriptive study, deals with measurement of normal diameter of the thoracic aorta in Sudanese population. The study conducted at computed tomography departments of Alribat National hospital , Alamal National hospital diagnostic center and Doctor's spthalized hospital. A 50 cases were selected randomly, The patients are not suffering from any pathological condition concerning the thoracic aorta. This study used the tools of computed tomography to measure the normal diameter of the descending thoracic aorta. The data designed to include the specific variables for the patients and were analyzed by SPSS program. The mean Length of the thoracic Aorta was 14.71±2.67 cm, The Proximal width of Aorta was 2.51±0.56 cm, the middle width of Aorta was 2.08±0.41 cm, the distal width of Aorta was 2.11±0.45 cm. The height and weight of the patient has showed no significant difference with the aorta diameter than the other variable (p-value is 0.000) respectively. Also highly significant difference (P=0.001) was detected between age and distal width of aorta, but low significant difference (P=0.018) was obtained between the height of the patient and distal width of Aorta. Also lower significant difference (P=0.015) was noticed between weight of the patient and distal width of Aorta. the study concluded that computed tomography is play a great role in the measurement of normal diameter of descending of thoracic aorta.

The diameter of thoracic aorta decreased in the tapering fashion distally from the aortic valve sinus
Aortic Diameter and Degree of Systemic Hypertension in South East Nigeria
2015
Background: The aorta, one of the largest blood vessels in the body, has an unusual closeness to the left ventricle. It contains bar receptors which control blood pressure. It is understandable that it would enlarge when there is increased blood volume load to the heart and to it. Objective: A prospective study done to determine the relationship between level of blood pressure and aortic diameter. The study done over three years involves 200 hypertensive’s attending the cardiology clinic in Enugu, Nigeria. They had routine Chest radiograph as part of their investigations for hypertension. Results: There were 134 females and 66 males. All had increased aortic diameter which increased progressively with age up to the age of 79. Female group had a more significant diameter increase (p-value =0.004) Males and females diameters when compared had statistically significant difference (p value =0.001) . Mean aortic diameter measured on plain chest radiograph in this study is 6.93±1.3.Conclu...
Normal thoracic aortic diameter in Thai people by multidetector computed tomography
Journal of the Medical Association of Thailand = Chotmaihet thangphaet, 2009
OBJECTIVE To determine the normal size of the thoracic aorta among Thai people. MATERIAL AND METHOD The aortic diameter of 73 Thai males and 56 Thai females, in four age groups, were measured from thoracic Multidetector Computed Tomography (MDCT) images. Aortic size were analyzed and correlated by age, sex, and vertebral body. RESULTS All showed normal aortic configuration, i.e. smooth tapering from aortic root to ascending and descending aorta. Mean aortic diameters were 3.12 cm at proximal ascending aorta, 2.95 cm at distal ascending aorta, 2.59 cm at mid arch, 2.33 cm at proximal descending aorta, 2.14 cm at distal descending aorta, and 2.03 cm at diaphragm. Males' aorta were larger than females, and all levels of the aorta were significantly enlarged with increasing age. Tapering of the vessel ratio of the ascending aorta/distal aorta at diaphragm was 1.5 without statistical significance. There was a weak correlation between aortic size and vertebral body at all levels. Comp...
Reference Normal Diameters of the Abdominal Aorta and Common Iliac Arteries in the Saudi Population
Cureus
The abdominal aorta is the largest artery in the abdomen. It then bifurcates giving the two common iliac arteries. Knowing the normal abdominal aorta diameter is a basis for diagnosing abdominal aortic aneurysms (AAAs) and subsequently developing an optimal management plan. In order to diagnose AAA, one must have a reference for the normal abdominal aortic diameter that represents the anatomical variation in the population being studied. The aim of this research is to establish normal abdominal aortic diameters in the Saudi population.
The epidemiology of abdominal aortic diameter
Journal of Vascular Surgery, 2008
Background: The diameter of the abdominal aorta is central to the diagnosis of abdominal aortic aneurysm. This study aimed to determine the associations between the diameter of the abdominal aorta at three distinct locations and the traditional cardiovascular disease risk factors as well as calcified atherosclerosis. Methods: A total of 504 patients (41% women) underwent whole body scanning by electron beam computed tomography (EBCT) and a standardized assessment for cardiovascular disease risk factors. The resulting EBCT images were retrospectively interrogated for the diameter of the abdominal aorta just inferior to the superior mesenteric artery (SMA), just superior to the aortic bifurcation, and at the midpoint between the SMA and bifurcation. Results: Mean patient age was 57.8 years. The mean (SD) diameter was 21.3 (2.9) mm at the SMA, 19.3 (2.5) mm at the midpoint, and 18.6 (2.2) mm at the bifurcation. In a model containing the traditional cardiovascular disease risk factors, age (standardized  ؍ 0.96), male sex ( ؍ 3.06), and body mass index (standardized  ؍ 0.68) were significantly associated with increasing aortic diameter at the SMA (P < .01 for all). The significance of the associations for these variables was the same for aortic diameter at the midpoint and bifurcation. Furthermore, a 1-unit increment in the calcium score in the abdominal aorta and iliac arteries was associated with 0.13-mm (P < .01) and 0.09-mm (P ؍ .02) increases, respectively, in aortic diameter at the SMA. The results were similar for the midpoint ( ؍ 0.19, P < .01;  ؍ 0.12, P ؍ .01, respectively) and bifurcation ( ؍ 0.09, P < .04;  ؍ 0.09, P ؍ .03, respectively).
Assessment of the Cardiothoracic Ratio and Its Association with Gender and Age: A Nigerian Study
Galore International Journal of Health Sciences and Research
Cardiothoracic ratio (CTR) evaluation is a useful screening method used to detect cardiomegaly. It varies in different populations due to genetic, geographical and environmental factors that influence body morphology. This study aimed at assessing the CTR and determining its association with gender and age among adult Nigerians. This retrospective cross-sectional study was conducted in the Radiology Department of a Teaching Hospital in Delta State after obtaining ethical clearance. Postero-anterior chest radiographs of 200 adults (108 males and 92 females) were used to measure the transverse cardiac diameter (TCD) and transverse thoracic diameter (TTD) in centimeters (cm). These were used to compute the CTR (TCD/TTD*100). Statistical Package for Social Sciences version 22.0 was used to analyze the data. Independent t-test and analysis of variance (ANOVA) were used to determine the differences in the measurements with regards to gender and age-groups respectively. The correlation tha...

PURPOSE-To determine the normal size and wall thickness of the ascending thoracic aorta (AA) and its relationship with cardiovascular risk factors in a large population-based study. MATERIALS AND METHODS-The mean AA luminal diameter was measured in 3573 Multi-Ethnic Study of Atherosclerosis (MESA) participants (age: 45-84 years), using gradient echo phase contrast cine MRI. Multiple linear regression models were used to evaluate the associations between risk factors and AA diameter. The median and upper normal limit (95 th percentile) was defined in a "healthy" subgroup as well as AA wall thickness. RESULTS-The upper limits of body surface area indexed AA luminal diameter for age categories of 45-54, 55-64, 65-74, and 75-84 years are 21, 22, 22, and 28 mm/m 2 in women and

Objective: Objective of the study was to determine the normal range of the diameters of three major branches of arch of aorta brachiocephalic trunk (BCT), left common carotid artery (LCCA), left subclavian artery (LSA) and to correlate diameters of branches of aortic arch with each other, age and gender. Material and Method: Multi slice CT scans were performed on 84 subjects (both male and female) in department of Anatomy, in collaboration with department of Radiology of Moti Lal Nehru Medical College, Allahabad and Kriti scanning center, Allahabad. The diameters of BCT, LCCA and LSA were measured at just distal to its origin from arch of aorta. Results: Mean diameter of BCT, LCCA and LSA were 1.14±0.20 cm, 0.71±0.16 cm and 0.93±0.17 cm respectively. Significantly high correlation was found between BCT and LCCA (r=0.62, p<0.001), BCT and LSA (r=0.59, p<0.001) and LCCA and LSA (r=0.59, p<0.001). Mean diameters of all three branches were increasing with the increase of age. Mean diameters of all variables were slightly higher in males as compared to females. Comparing the mean diameters between the two genders, t test revealed similar (p>0.05) diameters between the two genders i.e. not differed statistically. Conclusion: Among, branches of arch of aorta, the mean diameter of brachiocephalic trunk was the highest and left common carotid artery was the least (BCT > LSA > LCCA). Age had significant effect on diameters (diameters of branches of arch of aorta). Knowledge of normal diameters of branches of arch of aorta is helpful in the cardiovascular surgery, such as stenting and aneurysm.
