Abstract

Aim: was to estimate condition of aorta branches in case of aortic dissection, using multislice computed tomography (MSCT): we estimated frequency and type of changes of main branches of the aorta involved in the dissection.

Material and methods: a retrospective analysis of 104 patients with aortic dissection (AD) was performed. All patients were admitted to Scientific-Research Institute of Emergency Medicine named after N.V Sklifosovsky All studies were carried out on a multispiral (80x0.5) tomograph in early stages of the disease.

Results: MSCT method allowed to obtain data of the high frequency of transition of aortic dissection to main branches (63.5%), mainly to iliac arteries (81% and 77% of aortic dissection type A and B respectively), both in isolation and in combination with other branches. However, the frequency of occurrence of hemodynamically significant stenosis, both static and dynamic, was significantly higher in groups of visceral branches and brachiocephalic arteries (82% and 71%, respectively).

Conclusion: the CT method allows to evaluate in detail the lumen of the aorta and branches of aorta, and to determine type and degree of stenosis of aortic branches involved in the dissection. Revealed patterns of combining of involvement in different groups of aortic branches in the pathological process, allow to procced more optimized diagnostic search for complications of dissection, including MSCT.
