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 cere- brai angiography of 774 consecutive patients were included in the study. Angiography of aortic arch and the superselective angiography of its branch arteries were pedormed via femoral artery catheterization. The vari-ations 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 ①Aortic 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. ②With the increase of age, the proportion of Myla type I aortic arch decreased; the proportions of Myla type II and III aortic arch increased. ③With the increase of age, the inci-dences 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. ④With 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. ⑤Angiography on each aortic arch branch of 75l cases in this group was successful, and 23 cases failed, in which 5 because of variations of aortic arch, I 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 ex-ceptionally complex anatomy and imaging findings of aortic arch and make the cerebral angiography and inter-ventional treatment to be more safe and effective in combination with other 3-D vascular imaging technology.关键词
