Analysis of the morphology of aortic arch in the cerebral angiography / 中国脑血管病杂志

ABSTRACT

Objective: To analyze the variations and malformations of the aortic arch branches in the cerebral angiography and the changes of aortic arch in patients with different ages. Methods: The cerebral angiography of 774 consecutive patients were included in the study. Angiography of aortic arch and the superselective angiography of its branch arteries were performed via femoral artery catheterization. The variations and malformations of aortic arch branches were analyzed. The effects of age on the Myla type, the sharp angles of each aortic arch branches, the brachiocephalic trunk arising from the ascending segment of aortic arch, as well as the vascular tortuos conditions of the aortic arch branches were analyzed. Results: Circled digit twoAortic arch anomalies were found in 78 cases (10.08%). Of which 68 cases (8.79%) had aortic arch variations; 10 cases(1.29%) had aortic arch. Circled digit twoWith the increase of age, the proportion of Myla type I aortic arch decreased; the proportions of Myla type II and III aortic arch increased. Circled digit three With the increase of age, the incidences of the sharp angles of brachiocephalic trunk, left common carotid artery and left subclavian artery increased gradually, and the proportion of brachiocephalic trunk arising from the ascending segment of aortic arch increased. Circled digit fourWith the increase of age, the incidence of non-tortuosity in aortic arch branches decreased gradually, and the incidences of mild, moderate and severe tortuosities increased gradually. Circled digit fiveAngiography on each aortic arch branch of 751 cases in this group was successful, and 23 cases failed, in which 5 because of variations of aortic arch, 1 because of aortic arch malformation, and 17 because of advanced age, sharp singles on aortic arch branches, and severe vascular tortuosity. Conclusion: We should fully master the exceptionally complex anatomy and imaging findings of aortic arch and make the cerebral angiography and interventional treatment to be more safe and effective in combination with other 3-D vascular imaging technology.
