“…Findings from this audit also showed a male preponderance with a male:female ratio of 1.5:1. This is consistent with earlier reports by Anas and Muhammad[ 8 ] in 2012 in Kano northern Nigeria, Adekanmi and Osobu[ 10 ] in 2020, and Ogbole et al . [ 9 ] in 2010 both in Ibadan, south-western Nigeria, which also showed a male preponderance of 1.3, 1.3, and 1.6, respectively.…”

“…In this report from northwestern Nigeria, a total of 339 subjects were evaluated. The mean age of 49 years among the participants was consistent with 46 years reported by Adekanmi and Osobu[ 10 ] in a similar study in 2020 in Ibadan, which spanned over 8 years on CTA evaluation of vascular pathology in a Nigerian tertiary hospital. It is however lower than the 56–57 years reported by Ikpeme et al .…”

“…CTA is now becoming increasingly popular and represents the most important technological evolution in CT imaging over the last decades, using only IV contrast material thereby gaining acceptance as a quicker and safer alternative, less expensive, and noninvasive compared with conventional angiography.

“…[ 7 ] Previous studies have shown that most CTA studies were predominantly requested for the evaluation of cranial lesions. [ 8 9 ] Adekanmi and Osobu[ 10 ] had reported that most patients had cranial/cerebral CTA, followed by pulmonary artery CTA, and then lower limb CTA. The least requested CTA examinations were hepatic and cardiac CTAs.…”

Background: Computed tomographic angiography (CTA) is a promising tool for the rapid characterisation of the anatomy and structural lesions of the vascular system. Aim/Objectives: The aims/objectives of the study were to determine the frequency and pattern of vascular lesions in northern Nigeria. We also set to determine the agreement between clinical and CTA diagnosis of vascular lesions. Materials and Methods: We study patients that had CTA studies over a 5-year period. In total, 361 patients were referred for CTA, but only the records of 339 of them were retrieved and analysed. The information about patients’ characteristics, clinical diagnosis, and the findings on CTA was also retrieved and analysed. The categorical data results were expressed as proportions and percentages. The Cohen’s kappa coefficient (κ statistic) was used to determine the agreement between the clinical and CTA findings. A P value of <0.05 was considered statistically significant. Results: The mean (standard deviation) age of the subjects was 49.3 (17.9) years with a range of 1–88 years, consisting of 138 (40.7%) females. Up to 223 patients had various abnormalities on CTA. There were 27 (8.0%) cases of aneurysms, eight (2.4%) cases of arteriovenous malformations, and 99 (29.2%) cases of stenotic atherosclerotic disease. There was a significant agreement between the clinical diagnosis and corresponding findings on CTA showed for intracranial aneurysms ( k = 15.0%; P < 0.001), for pulmonary thromboembolism ( k = 4.3%; P < 0.001), and for coronary artery disease ( k = 34.5%; P < 0.001). Conclusions: The study found that close to 70% of the patients referred for CTA have abnormal findings, out of which stenotic atherosclerosis and aneurysm are the common findings. Our findings highlighted the diagnostic value of CTA variety of clinical conditions and underscored the prevalence of many vascular lesions in our environment, which hitherto were regarded as uncommon.
