Abstract

SUMMARY


Objective: The relationship between the thoracic aortic dilatation and the degree of coronary artery injury by 256-slice CT scanning.
Subjects and methods: Descriptive cross-sectionalnstudy was performed on 207 patients who was performed coronary angiography by 256-slice CT scanning at Bach Mai hospital from January 2019 to August
2019.
Results: 207 patients in study, 107 males (52,7%), 98 females (47,3%). Average age is 62,2±10,3. There was 34 patients with thoracic aortic dilatation (16,4%). There was the significant difference of the Dmax, Dmin diameter at levels (sinuses of Valsalva, sinotubular junction, ascending aorta, descending aorta) and Dmin diameter at level of annulus between the systolic phase and diastolic phase (p<0,001. There was relationship between dilatation of thoracic aorta with valve calcium score (p<0,001). There was not relationship between dilatation of thoracic aorta with coronary artery calcium score and degree of coronary artery stenosis due to atheroma.
Conclusion: This study showed significant differences of the thoracic aortic dimensions, between systolic phase and diastolic phase. Dilatation of thoracic aorta was associated with aortic valve calcium score
but not with degree of coronary artery injury.
