孤立性锁骨下动脉的影像学诊断

Imaging Diagnosis of Isolated Subclavian Artery

目的:探讨孤立性锁骨下动脉(ISCA)的影像学表现及其诊断价值。方法:对14例孤立性锁骨下动脉的影像学检查结果进行回顾性分析,其中10例行DSA、3例行MRI、2例行CT检查。结果:14例患儿均显示一侧的锁骨下动脉与主动脉弓间无连接,而由同侧的椎动脉供血,2例同时由肋间动脉供血,1例同时由腹主动脉发出的侧枝血管供血;4例孤立性锁骨下动脉与同侧的动脉导管连接。结论:孤立性锁骨下动脉通过影像学检查能作出正确诊断并指导临床制定治疗方案。

Objective：To study the imaging manifestations and its significance in the diagnosis of isolated subclavin artery. Methods： Imaging findings of fourteen cases with isolated subclavin artery were retrospectively analyzed. 10 patients had DSA, 3 patients had MRI and 2 patients had CT. Results：Fourteen patients showed unilateral subclavian artery lost the connection with aorta and the blood supply came from homolateral vertebral artery,blood supply came from the intercostal artery simultaneously in two cases,and one patient had blood supply from the collateral blood vessels arisen from the abdominal aorta. Isolated subclavian artery connected with homolateral duetus arteriosus in four cases. Conclusion： Isolated subclavin artery could be diagnosed correctly by imaging examination,which is helpful in the guidance of clinical treatment planning.
