SUMMARY

Objective: to describe the imaging characteristics of aortic aneurysm using 256 rows of detectors computed tomography scanner.

Subject and Method: cross-sectional descriptive study on 78 patients with aortic aneurysm, who were diagnostised by computed tomography scanner with 256 rows of detectors from March 2019 to the end of February 2020 at Friendship Hospital.

Results: 93.6% in male and almost in elderly (> 60 years old). Risk factors were hypertension, diabetes, cerebral artery accidents due to hypertension and increase of blood lipid concentration. The aortic aneurysm with maximum transversal diameter ≤ 5 cm accounted for 79,8 %; The length of aneurysm from 5-10cm accounted for the highest proportion (50%), other groups were equivalent. Fusiform aortic aneurysm accounted for 88%. Abdominal aortic aneurysm had highest proportion (69%). Common iliac artery lesion was 39,3%, however it accounted for 56,9% of abdominal aortic aneurysms and 94,3% of branch injuries. Aortic aneurysms were often accompanied by atherosclerosis and calcification (83%); wall thrombose (89.6%). There were 7.1% of cases accompanied by endothelial dissection.

Conclusions: 256 rows of detector CT scanner allows to diagnosis accurately all lesions of aortic aneurysm and plays an important role in diagnosis and monitoring patients suffering from aortic aneurysm.

Key words: aortic aneurysm, 256 rows of detector CT scanner
