大动脉炎综合征的影像表现特点

Imaging features of aortitis syndrome

目的 讨论多发性大动脉影像表现特点。方法 46例大动脉炎综合征病例 ,经普通血管造影 7例 ,DSA造影2 3例 ,MR检查 8例 ,DSA和MR检查 4例 ,DSA和CT检查 4例。结果 大动脉炎综合征病变以狭窄 阻塞型最常见( 73 .9% ) ,按Lupi Herrea分型以Ⅲ型多见 ( 4 3 .5 % ) ,最常受累的血管为左锁骨下动脉 ( 69.6% )及左颈总动脉 ( 60 .9% )。结论 大动脉炎综合征多部位血管受累多见 ,以狭窄 阻塞型常见 。

Objective To realize the special features of aortitis syndrome. Methods Total 46 cases with aortitis syndrome were examined with angiography (7 cases), DSA (23 cases), MR (8 cases), DSA and MR (4 cases), or DSA and CT (4 cases). Results The steno-occlusive type was most common (73.9%) in aortitis syndrome. According to the classification of Lupi-Herrea, type Ⅲ was observed in 43.5% of all. Left subclavian arteries (69.6%) and left common carotid arteries (60.9%) were the most frequently involved. Conclusion The aorta and its major branches are frequently involved in aortitis syndrome, and the steno-occlusive type is common. CT and MRI can demonstrate variable evolution of vascular lesions.
