Subclavian steal may occur in newborns with interrupted aortic arch (type B) as a result of collateral circulation. Color Doppler flow imaging could detect reversed blood flow images in the diastolic phase at the subclavian artery of two neonates with interrupted aortic arch (type B), indicating subclavian steal phenomenon at the left subclavian artery via the left vertebral artery. The diagnoses were confirmed by retrograde angiography from the radial artery.
锁骨下动脉盗血现象可能发生于主动脉弓中断（B型）的新生儿，这是侧支循环的结果。彩色多普勒血流成像可检测到两名主动脉弓中断（B型）新生儿锁骨下动脉舒张期的反向血流图像，提示左锁骨下动脉通过左椎动脉出现锁骨下动脉盗血现象。诊断通过桡动脉逆行血管造影得以证实。
