Background: The aortic knob (AK) is an essential feature on a chest x-ray. It could be the first sign of a cardiovascular problem if there is any deformation or enlargement of the knob. This study aimed to measure the normal AK diameter (AKD) on a posteroanterior chest radiograph in healthy adult Sudanese. Methods and Results: The study was conducted in the Department of Radiology and Imaging in Ribat Hospital (Sudan) between Jun 2019 and Jan 2020. A total of 113 participants of both sexes (45.1% males and 54.9% females) with a normal chest x-ray and no history of diabetes, blood hypertension, cardiovascular disease, or skeletal abnormality were selected. Participants' age fluctuated from 18 to 75 years. The measurements (AK, heart diameter [HD], cardiothoracic ratio [CTR]) were carried out with the measuring tools available on the software of the computed radiography system. The mean AKD was 2.8±0.8 cm (2.94±0.8 cm in males and 2.51±0.77 cm in females, P=0.005)). The mean HD was 9.22±2.8 cm (9.8±3.3 cm in males and 8.7±0.2.1 cm in females, P=0.005). The mean CTR was estimated as 46.6±7.7% with a significant difference between males and females and significantly correlated with HD and BMI (P<0.05). The AKD increased by 0.0199 cm with an increase of one year of age (AKD = 0.0199(age)+1.9469), and there was a strong positive correlation between age and AKD (P<0.001). Conclusion: The study found a significant positive correlation between age and AKD. Increased heart sizes increase AKD. The AKD value is greater in males than in females.

This study determined cardiac sizes, with the aid of chest radiographs, using the mean values of the CTR among adult Ijaws in Nigeria. Chest radiographs of 200 adult Ijaws were obtained and placed on a radiological illuminator box to reflect proper views of the radiographs, as cardiac and thoracic diameter values were collected. Data were analysed using SPSS for total number determination, mean, range, standard deviation and t-test value. The results recorded as follows; mean cardiac diameter for males is 13.44±1.10cm; that for female is 12.52±1.20cm and 12.98±1.19cm was recorded for both gender. For mean thoracic diameter, male value is 29.76 ± 1.85cm, that of female is 26.77±1.84cm and 28.26±2.37cm was recorded for both gender. Also the mean CTR (cardio-thoracic ratio) value was also recorded; the value for male is 45.22±3.19, that for female is 46.88±3.87 and 46.05±3.63 was recorded for both gender. Statistical analysis using student t-test showed that male adult Ijaws had higher value (p<0.05) in almost all the parameters except in CTR value, whereas females have higher CTR value (p<0.05). Findings of the index study (46.05 CTR values) provides a reference point for future studies on other Nigerian ethnic groups, which will in turn enhance better clinical interpretations necessary for diagnosing cardiovascular disorders.

Background: The clinical show of illnesses including the thoracic aorta goes from countless patients who have no symptoms, having a medically imperceptible thoracic part of the Arora to victims with side effects of extreme ribcage torment because of intense aortic analysis. Objective: A retrospective study was conducted in computed tomography CT departments of three hospitals to quantify the average thoracic aorta width in the population of Sudan to compare it with international measurements. Methodology: The data collected from 500 randomly selected non-pathological patients were analyzed by the SPSS program and presented in tables and figures. Results: Results revealed that the diameter of the aorta is affected by the body length, age of the patient, and weight, except the gender which is a non-significant factor. Also, the typical size of the plunging part of the Aorta was 12.17±1.78 cm, the proximal diameter of the aorta was 2.51±0.56 cm, the focus width was 2.08±0.41 cm, and th...
A Multicentre Study of Abdominal Aorta Diameters in a Turkish Population
Journal of International Medical Research, 2002
The aim of this study was to determine the normal values for aortic diameters and the prevalence of aortic dilatation in a mixed Turkish population. Between March 1998 and May 2000, patients who were undergoing abdominal ultrasonography examination for pathologies not involving the aorta, in three different cities, were enrolled into the study prospectively. The anterior posterior aortic diameters were measured at the subdiaphragmatic and aortic bifurcation levels using ultrasonography. A total of 596 patients were included (302 females, 294 males). The mean age was 48 ± 16 years (range, 6-88 years). The mean aortic diameter in the whole group was 19.0 ± 3.9 mm (10-45 mm) at the subdiaphragmatic level and 15.7 ± 3.6 mm (9-65 mm) at the aortic bifurcation level. The mean subdiaphragmatic aortic diameter was 18 ± 3 mm in females and 19 ± 4 mm in males. The mean aortic diameters at the bifurcation level was 15 ± 3 mm in females and 16 ± 4 mm in males. An aortic bifurcation diameter > 30 mm was encountered in 0.67% of the population. This ratio increased to 1.8% in patients over 55 years of age, regardless of sex. A subdiaphragmatic aorta diameter above 30 mm was observed in 1.2% of the population. In patients over the age of 55 years, this ratio increased to 2.7% (3.6% in males and 1.9% in females). In this national study, the subdiaphragmatic aortic diameters were similar to mean values reported in the world literature. The mean aortic bifurcation diameters were generally lower when compared with the literature, which may be due to difficulties in standardization of the measurements. Aneurysmal dilatation rates in this study also conform to those reported in studies conducted in other countries. Considering the significant number of patients with aneurysmal dilatation of the aorta in the elderly population, we believe it would be prudent to evaluate the aorta in all patients undergoing abdominal ultrasonographic examination.

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.

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).
