Abstract:Objective To evaluate the value of beam arm test in the diagnosis of symptomatic subclavian steal by Doppler ultrasound. Methods From August 2014 and January 2017, in China Academy of Chinese Medical Sciences Guang'anmen Hospital, 62 patients confirmed subclavian artery stenosis by digital subtraction angiography (DSA), magnetic resonance angiography (MRA) or computer tomography angiography (CTA) were selected,the direction, velocity of bilateral subclavian artery and vertebral artery the resistance index of vertebral artery were measured, the changes of spectrum shape were observed after beam arm test. Results There were totally 20 cases were steal blood,18 cases were partial steal in blood, 20 cases were occult steal in blood, and 4 cases were no obvious steal blood; 17 cases of occult steal images were converted into partial steal after brachial beam test. Conclusion Ultrasound can accurately diagnose the degree of subclavian artery stenosis by observing the direction of vertebral artery blood flow and the characteristics of blood flow spectrum; beam arm test is a useful supplement to ultrasonic diagnosis.
